Spring Boot Tricky Questions -3

In a Spring Boot application, you need to change the default port in Spring Boot. How can this be achieved? which of the below-mentioned answer is correct. Using the command line when running the application as a jar file, we can set the server.port as a java command Dserver.port argument. Using a properties file we can define this in an application.properties (or application.yml) file using…

Wow holy shit wasn't expecting people to actually like the idea of Menace reader so here's part two! Part three in the works with a poll on the end of this one to see how it goes. Enjoy :)

Thus begins the prank war.

It would go back and forth for a few weeks, Menace constantly finding new ways to make sure they're never one upped by the other operators in playful retaliation to their pranks.

For example: they knew it was Gaz who painted "dickhead" on their helmet with glow in the dark paint, so in turn they messed with the bottoms of his boots so they squeaked with every step. When Kyle had seen Menace after the fact, he chased them down while they cackled like a hyena becauae who wouldn't laugh if the person chasing them had squeakers strapped to their heel.

Or how Soap managed to switch out Menace's body wash with a menthol infused one— so when he caught Soap in the shared restrooms he dumped ice cold water onto the man's bare back and head. Never before had Menace needed to run out of a shower so fast to the sounds of Scottish yeling, but John learned to shower whenever the Coperal was fucking off somewhere else.

When the Price and Ghost managed to inconvenience Menace by changing the keyboard configuration on their computer and unscrewed the bolts of their chair... they responded in kind by seran wrapping Every. Single. Item in Price's office when he was on a mission. Though truly this one backfired as they were called into the same office nearly an hour later— running face first into a near invisible seran wrap blockade that was hiding in the doorway, and they had to help unwrap all of their hard work.

They had even replaced all of Ghost's nice, full pens with shitty one's that are completely empty when they knew he had a lot of writing to do that day. Little did they know he kept a pen on him at all times, but they did hear soft swearing from his office when they passed by— mild inconveniences worked best on him, after all he had briefly mentioned that life was a big inconvenience as is.

It's all fine and dandy, but Menace knows they have to step up their game.

Then one of them winds up in a snare trap that Menace set on the path around the base, only for said trickster to pop out of a bush wearing a ghillie suit they stole from sod earlier in the day. They'd been waiting all day for John to spring their trap and now that they got him where they want him, what happens?

Three words.

Pool Noodle Piñata

Menace doesn't even let the man get a fighting chance before they're whacking him in the stomach, only to dart away when they realized he hadn't come alone. John and Kyle had come with water guns to find them, and they nearly yelled at the ice cold water that just barely sprayed their back.

The new idea of the pseudo guerrilla prank warfare was entertaining to say the least... and provided a good means of training for practically everyone at the base. After all, some other soldiers had gotten into the crossfire multiple times. Whether it be the salt that had been replaced by sugar, or stumbling into an office that had just been boobytrapped for someone else.

Everyone knew how to be professional when they needed to, but when they didn't have to there were the occasional nerf gun fights in the cafeteria led by none other than Menace themself, or a water balloon strike from the roof of one of the buildings.

Team building exercises they would call it others would call it an uprising. But the operators of 141 knew better, especially after realizing how Menace meant no harm— this is just who they were.

Their harmless trickster.

The same harmless trickster who comes back from a mission to find that their office had been fully gift-wrapped and the boys who had done it were hiding behind the door with swords fashioned from the sane pool noodle they used on Johnny.

Though the bottle of glitter Menace had picked up along the way came in handy since they were all in once space together. To this day everyone is picking glitter out of their hair or clothes. So who really won this time.

just for a season (09Ghoap, YoOTP25)

Hanahaki Disease (non-fatal), Historical AU, Mer AU. 09Ghoap, minor John Price x John Soap MacTavish

MacTavish didn’t think he would stay for long at the lighthouse when he’d first arrived on the island. The village itself on the shore just beyond had been more familiar, a low-slung huddle of thatched cottages on the outskirts that congealed into brick and mortar, some storefronts and the bones of a marketplace, a few pubs and he could be content there for a time. The lighthouse had been a scar on the horizon, some artistic rendition of a wizard’s tower thrown on a drunkard’s pottery wheel, and MacTavish had staggered from the small boat sent to ferry him across to it wearing the remnants of his final pint splattered across his boots into the arms of one John Price. 

“Only need you to stay for a season, lad,” Price had said, one hand pressed to MacTavish’s forehead to keep him upright, the other resting above the keys at his waist. “Just a season and we’ll send you off to your nice soft bed with some coins in your pocket and a few hairs on your chest.” 

MacTavish couldn’t say what colour Price’s eyes had been, but he sketches them in charcoal on the corner of tattered sailcloth strung up along the side of his bunk that first night, the roar of lighthouse horn enough to pluck him from fitful sleep minutes before it sounds. He spends that first breakfast tipping forwards into his plate, a fry-up for the first day after a resupply, strips of bacon fried in their own fat and bread neatly hacked from the loaf and toasted in front of the fire, while Price chuckled, wreathed in smoke and salt like some deity of old. His fingers were crooked, weathered and pale as driftwood, but he’s fast with them, smacking across MacTavish’s knuckles with the flat of his knife to keep him awake, to keep him alert, and just because he could. 

He’d hated the man and adored him in equal desperate measure.

One season bled into two, to three, to one bitch of a winter when MacTavish curled up in Price’s bed to steal any memory of warmth from his sheets, and then another.

Then, there was war.

Two men left the lighthouse.

One man returned.

“They’ve asked me,” MacTavish begins, tapping the ash from his cigarette into his mug. It’s mostly paper and char by this stage of the month but he returns it to his mouth all the same, tastes the stale tang of damp tobacco. “If I want to stay on the rock for another season.”

He plucks two cards from his hand, their edges soft with age and warped by the salt in the air, holds them aloft before he adds another, laying them all down on the stool that sits between the two men. It’s a strange configuration; MacTavish slung in the low-backed armchair, the frame moulded to fit a different man’s shoulders, the angle of his hips. He sits forwards, legs spread wide and laces trailing from his boots, half-loosened as the evening stumbled onwards, and sinks back against protesting springs. Riley presses himself upright, the cloying scent of brackish water clouding the air like a lover’s perfume, and the water sloshes against the side of the copper bathtub he’s folded into. If Riley had been any other man, it would be a private affair, MacTavish busying himself with his sketchbook or the snarl of his thoughts. 

Riley blinks at him, first one set of lids — milky white like death’s first kiss — then the other, dark lashes spilling shadows across his cheeks. “What did you say to them?”

There’s dark indentations splashed across his forearms from the edge of the tub, harsh lines woven over the paler sheen of scale and skin. Riley leans closer with a slosh of water, three cards held between thumb and forefinger before he drops them on the stool. He has a way of looking up at MacTavish — a necessity given their seating arrangements but it runs deeper than that — like he’s studying him in the same way a religious man bleeds over his bible. 

“They’re not wrong for asking, there’s meant to be some new blood on the rock for years now.” MacTavish drags blunted fingers over his jaw, scratches at the line of his neck. “Could be a younger man for you to bite at over cards, with a pretty wife and a baby. More interesting company for you than an old man.”

Riley hums, his jaw tight. It doesn’t sit even, the scars at the corner of his mouth drawing his grin jagged, the curve of his teeth constantly on display. “No, you’re fine.”

“It’s like you’re trying t’make me blush.” MacTavish shifts his cards between his fingers, places them all flat on the stool, only to pick them back up again. The evening air is cool, a distant prickle against the nape of his neck, the edge of his wrists, and he considers rising from his seat and crossing the expanse of four steps to the huddle of the stove and throwing another piece of driftwood in. It would burn beautifully, a riot of purple flames devouring the pale sculpture, but that would be a step away from Riley, from the deliberate weight of his gaze.

MacTavish stays where he is.

“What would you do in town?” Riley asks, his teeth exposed in something more than common flesh healed jagged. There’s seaweed tangled in his hair, dark against the sodden curls, never able to fully dry but golden all the same. “Your own pretty wife, a baby?” 

MacTavish laughs then, really laughs with his head thrown back and chest aching from the effort. His ribs had never healed right from his first tumble into a foxhole, fresh blood on his palms (his, Price’s, the laughing lad next to them) and every breath sends a pang echoing through the memory, crashing into the swell of the present. Price had pulled him from the stinking mud, slapped him on the back before his hand rested on MacTavish’s shoulder, keeping him upright, keeping him steady. 

“No, lad.” MacTavish chucks down his cards, clearing his throat before he swallows down the mud of a foreign field he hopes to never see again. He draws another pull of his smoke, the dull glow burning steadily to his fingers, and breathes out through his nose. “No wife, though it wasn’t for a lack of them trying when I was younger. Must’ve told you this before—” He looks to Riley, tipping his head to one side in question. They’d spent countless nights together living in the same cramped quarters, the aging lighthouse keeper and the mermaid in his bathtub, and the details blur together in MacTavish’s memory, faded like an old photograph that’s been exposed too many times and the image beneath bleeds through. Riley shrugs, layering his arms over the edge of the bathtub and resting his chin upon them. Could be an oil painting of a cherub torn straight from the church walls and MacTavish abandons his cards on the stool without a second thought, reaching for the bloated curve of his sketchbook, pencil jammed between the pages. 

“Anyway,” he says, scratching out the blunt beginnings across an empty corner of a page. “When I was younger, back when I kept saying I was only staying on the rock for a season, I had a handful of girls trying to court me.” It had been a heady, if uncomfortable, sensation as a young man, giddy excitement of being craved warring with the bitter panic that something isn’t right, something with no shape or name but it existed all the same. His older sister had brought home an unbroken colt once and he’d felt the same as that beast; trying to flee a world that did nothing but exist. “Few of them were Heartsick over me, wore their flowers in their hair so I’d notice.”

He couldn’t remember their names, but he remembered their flowers, the same ones that would likely litter their pillows in the morning or be chewed and swallowed along with their food, a bouquet of red roses, some pink, daisies, primroses. Their scent hung heavy on the morning air, mixing with the smoke of the incense in church as MacTavish took one hand between his own, lowering his face to whisper a blessing that would be devoured in one starving blink. The affliction wasn’t fatal, a byproduct of God’s love for his creations or some quirk of human biology if the doctors were to be believed, but it could be inconvenient for the sufferers. The radio plays and serials would use it to raise the stakes in their romantic subplots, sending out the fresh-faced female leads with a wreath of roses woven into her hair or the plotting step-sisters with fresh blooms cut from the garden. 

“Although,” MacTavish tears himself free of the memory, the remnants of it clinging to his arms, his hands like dust. “If you’re asking because you’re a siren, Riley, then you’ll have a poor last meal from me.”

Riley chuckles, the sound closer to the scratch of a match than anything a human could produce. His tail shifts, the dark fins stretching above the water to counter his movement, a ripple of muscle down its surface as Riley lifts himself upright, seawater sloughing off his skin. He’s human from the waist up, the sharp concave line of his belly warring against the onslaught of pale scales, his navel blank except for the scars that stretched across it; one set over his hip, another straight up the centre of him, a handful more curving over shoulder and forearms, before the deliberate devastation of his throat and jaw. There’s a few tattoos visible on his upper arms, the edges of one on his collarbone, and another on his ribs, and MacTavish marks them quickly on his sketch, smudges his thumb over the hurried outlines. Riley doesn’t move when MacTavish isn’t watching him, dark eyes catching the embers, the faint glow of MacTavish’s smoke. He holds out one webbed hand expectantly, and MacTavish hands the cigarette over with a rueful sigh. He doesn’t mind, not truly. The end glows a pittance in Riley’s hold, the smoke barely more than a wisp as he breathes it in, the memory of it rolling from the gills in his neck like morning mist inland, pale and barely there. 

“I don’t think I’d see much of you if I left the rock,” MacTavish says, returning his gaze to the cards spread out in front of them, his sketchbook balanced on his lap, his pencil tucked behind his ear. There’d be grey lines over his temple later, dark against the silver shot through his hair. 

Riley drops his set of cards down, nudging them into place before he returns the cigarette to his mouth. It’s down to the paper now, grey ash falling free over Riley’s fingers, floating on the surface of the water like soap scum. “I could go with you.”

MacTavish first met Riley the night after a storm. It had been his second or third season at the lighthouse, his legs growing steady with every step over the slick rocks, the salt crystallising down to his bones. Price had dropped a basket onto his chest, mercifully empty, and sent him out with a smack to the back of his head, Price’s jumper sitting wide on his shoulders and long on his hips. Seagulls wheeled high overhead, shrieking to each other and dropping out of the slate-grey sky to pick at something on the ground, barely visible at first as MacTavish made his way over. He’d expected some fish, their eyes already glassy or missing, just empty husks staring up at a sky they were never meant to see; but what he found was a man, his skin scraped raw and bright over his hip, his elbows, blood and feathers clinging to his palms, his mouth. 

“Fuck off,” Riley had snarled, his voice barely louder than a rasp behind the display of his teeth, and MacTavish only laughed, a mixture of disbelief and wonder rattling through the empty spaces between his bones, the universe reshaping itself because of one chance encounter.

“You’d go with me?” MacTavish asks, leaning back in his chair and letting his legs slide wider. He’s got a small cottage back on the mainland, it had been Price’s like so many things that MacTavish owns now, just another thing folded into his hands alongside a black-edged telegram that was too small to contain the full breadth of the man it trapped in dark typeface, the man who would be forgotten as just another name amongst the war dead. 

It’s big enough for two.

MacTavish hums quietly, reaching for a smoke he no longer holds. He pushes himself up from the chair, the creaking of the springs only masked by the cracking of his knees, a line of pressure caught tight in his back. He staggers his first step towards the low slung cabinet, but catches himself on the second, the third. Another wail of the horn high overhead, the carrion call of some enormous bird, and MacTavish pulls fresh rolling papers, a folded paper package of tobacco. “Another?” he asks over his shoulder, drinking down the shadowed lines of Riley’s features as he slouches against the line of the bathtub, his fingers twisted in the seaweed caught in his hair. 

“No,” Riley murmurs, far gentler than he has any right to be. Drawing him wouldn’t be enough, MacTavish could fill every inch of the lighthouse with his visage, carve the smooth curve of his form into the rock itself so someone, somewhere can dig it out of the ruins and marvel, and it still wouldn’t be enough. MacTavish is stubborn and sullen, a ruined husk of a ship from a bygone age left to rot in the sun, with salt on his hands and an anchor looped around his neck, never more than a handspan away from the terrified lad who breathed in the thick scent of blooming roses and wondered why he didn’t feel anything.

MacTavish dampens one edge of the paper, tapping out a thin line of tobacco, rolls, and lights it. Riley wins the game, his grin sharp behind his facade of indifference, blood scented in the water and leapt upon, and MacTavish blackens his lungs with every inhale, the taste sharp across his tongue. 

“Going to be a storm tonight,” Riley murmurs. The fire has long since burnt to embers, the room cast in pale shadows, and his eyes gleam strangely in the low light, dual eyelids shimmering with every blink. “You should sleep.”

“Aye.” MacTavish stands, presses his hands into the small of his back as he leans against it. Riley lifts himself partially from the tub to sit on the edge of it, the sharp bite of the sea ever present. 

He’s solid in MacTavish’s arms as he lifts him, Riley’s arms locked around his neck and the curving tattoo on one bicep the point of MacTavish’s focus as they breathe in tandem, for a moment, a single entity. The lighthouse howls above them, around them, and Riley twitches, his tail fin flaring wide in a ripple of muscle down the length of it, his jaw clenched tight as he turns his face into MacTavish’s neck, his breath damp against his skin, the fall of his crucifix. 

“You alright, Riley?” MacTavish murmurs as he makes his halting way down the stairs, his shoulders turned to keep Riley’s tail clear of the narrow stone walls. 

“Yes,” Riley answers, his voice thick. His hands twine in the loose strands at the nape of MacTavish’s neck, the sharp edge of his claws scratching delicately at his scalp. 

Their parting is inevitable, the roar of the sea against the edge of the broken sluice gate louder than the lighthouse overhead, the marrying of their two worlds. MacTavish kneels, the stone damp and soaking into the light fabric of his trousers, matching the ocean already emblazoned across his chest and belly, the rivulets slipping over the edges of his spine, and he hasn’t been inside a church in years but here is sacred enough for him to worship. Riley slides from his hold, catching himself on the edge. “Sleep well,” he murmurs, his words almost lost beneath the roar of the water, and then he is gone. 

MacTavish returns to the huddle of his rooms, a thin trail of smoke fluttering behind his every step like a bridal veil. His thoughts are muffled, echoing through shattered bone and tangling around the snarl of his ribs, the stagnant cling of his heart, and he thinks of Riley, Riley in the old-wheeled chair gathering dust in the corner of Price’s, of his front room; the double bed that always felt too big for him so he spent his nights stretched out in front of the fireplace, seeking salvation from cool stone and the distant hiss of the ocean. He sleeps but he doesn’t dream, and wakes with a rose petal between his teeth. 

It tastes like his ma’s perfume, a deliberate steeping of the fresh spring cuttings, and he spits it out into the trembling cup of his palm. Dark enough that he can barely make out of the shape of it in the gloom, the air trembling with the aftermath of the lighthouse’s call, but he knows it by the musky tang coating his tongue, the scent heavy in the air and the space behind his teeth. MacTavish brushes his fingertips over the gentle crush of it and tucks the petal behind his ear, blinking out into the darkness. 

In the distance, inside the emptiness of his thoughts, he hears the roar of the ocean.

///: Omni-Net Link Established... Heading: Introduction

Longshot-X: Okay. Let's take this from the top.

Longshot-X: How's it going, Omni-Net? My name is Ryker, callsign Longshot, I'm sort of a de-facto head of the 37th Vanguard Mobile Response Team, but we usually just go by our nickname these days: "The Bowshocks.", after our founder's mech. We specialize in two things: Showing up quickly, and shutting down incursion forces, police actions against innocent civilian pops in unstable environments, invasions by petty tyrants, pirate interdiction (okay, maybe like...two of us are equipped to do it without some kind of EVA add-on), search and rescue, and various other tactical configurations to best suit your burgeoning planetary democracy/republic/democratic republic. We go loud or we go quiet, but we always go.

Our Team is a pretty diverse bunch of folks, in addition to support staff, our team consists of:

Longshot - Yours truly. Specialties in Flight, CQB Interdiction, and High-Speed Operations. I pilot an ASV Peregrine.

Sureshot - Goes by Mohamad or "Mo". He/Him. My best buddy out here, a Pure Sniper. He cut his teeth back home and we met when the Bowshocks came to his world, and joined up after the operation was over. Has a lower resting heart rate or something. Either way, Mo's fuckin' lethal. Nobody I'd rather have as backup. Pilots an IMI Zephyros.

Trickshot - Marigold. She/Her. MASSIVE infiltration expert. Former HA...among some other stuff she loves to kind of spring on us. Not a huge fan of that, but she gets results. Pilots a """Kuzutov""".

Glamourshot - Clarissa, She/Her. She gets called "Lady Clarissa" or "Princess" by just about everybody, not that she cares. We thought she was gonna be just a financier and then uh...she turned out to have a VLAD and a considerable knowledge on how to use it. There isn't really a real designation I would give her tactically beyond "Shock Doctrine" and "Psychological Warfare". NOT AVAILABLE FOR ANY MISSIONS IN KARRAKIN OR DAWNLINE SHORE SPACE. CANNOT STRESS THAT ENOUGH. DO NOT ASK. In fact we're probably going to limit her knowledge of this link just to keep us out of any Karrakin grudges or warcrime lists.

Ironshot - Bruno. He/Him. I genuinely do not know what they did to make a guy that big on an agricultural colony. Seriously, dude's built like a fucking house. Makes an incredible chicken parm, though! Love him to death. Turns out he has some real funky ideas on how to break sieges, though that's pretty easy to do when you're piloting something that big. Pilots a WAZAL TR-10 Indigo Dream.

Moonshot - Charity. She/They. Kind of a space case, Aun defector lady. Frankly I'm stunned she even has the licenses she does, but she's good with that bow. She would like to impress that you are loved and that Metat Aun has a plan for us all. Pilots an SSC Emperor.

Buckshot - We found her in a SecCom lab some desperate shithead despot decided to boot back up. We got her out but we know next to nothing about her and she doesn't remember a thing. She doesn't say much, but she's great at following orders. Anybody who knows a "Jasper Ryan" from the Sierra Madre line, Anticentre region of Union space? Please hit us up. We'd like to know more about her because she's frankly a complete mystery. Pilots an Everest.

Spring Boot Interview Questions: Prepare for Success

Spring Boot has become one of the most popular frameworks in the Java ecosystem, streamlining robust and scalable web application development. Whether you’re a seasoned developer or just getting started, acing a Spring Boot interview can be a significant milestone in your career. To help you prepare effectively, here are the latest Spring Boot interview questions that will test your knowledge and give you a deeper understanding of how the framework works. These questions will be beneficial if you're pursuing a Spring Boot Certification Training Course at eMexo Technologies, in Electronic City Bangalore.

1. What is Spring Boot, and how is it different from Spring Framework?

This is a fundamental question that often appears in Spring Boot interviews. Spring Boot is an extension of the Spring Framework to simplify the development process. It eliminates the need for extensive XML configuration and provides default configurations to facilitate rapid application development. Spring Framework requires developers to configure components manually, while Spring Boot auto-configures them.

By understanding this, you can highlight how Spring Boot training in Electronic City Bangalore at eMexo Technologies helps developers focus more on writing business logic rather than dealing with complex configurations.

2. What are the main features of Spring Boot?

Spring Boot stands out due to several features:

Auto-Configuration: Automatically configures your application based on the libraries on the classpath.

Embedded Servers: It allows the deployment of web applications on embedded servers like Tomcat, Jetty, and Undertow.

Spring Boot Starters: Pre-configured templates that simplify dependency management.

Spring Boot CLI: A command-line interface that allows you to develop Spring applications quickly.

Actuator: Monitors and manages application performance.

These features make Spring Boot an attractive option for developers, which is why the best Spring Boot training institute in Electronic City Bangalore emphasizes hands-on experience with these functionalities.

3. What is the role of @SpringBootApplication in Spring Boot?

The @SpringBootApplication annotation is a core part of Spring Boot, often referred to as the ‘meta-annotation.’ It is a combination of three annotations:

@Configuration: Marks the class as a configuration class for Spring Beans.

@EnableAutoConfiguration: Enables Spring Boot’s auto-configuration feature.

@ComponentScan: Scans the components within the specified package.

This annotation is crucial to understanding Spring Boot’s internal architecture and its ability to simplify configuration.

4. What is Spring Boot Starter, and how is it useful?

A Spring Boot Starter is a set of pre-configured dependencies that simplify the inclusion of libraries in your project. For instance, spring-boot-starter-web includes everything you need for web development, like Spring MVC, embedded Tomcat, and validation support.

Starters save a lot of time, as they eliminate the need to find and include individual dependencies manually. When studying at eMexo Technologies, you’ll get an in-depth look at the variety of Spring Boot Starters available and their importance in building scalable applications.

5. What is a Spring Boot Actuator, and how is it used?

Spring Boot Actuator provides production-ready features to help monitor and manage your Spring Boot application. It offers a wide array of tools like health checks, metrics, and auditing endpoints. The actuator allows you to easily monitor application performance, which is a crucial aspect of microservices-based applications.

6. What are Microservices, and how does Spring Boot help in building them?

Microservices are small, independent services that work together in a larger application. Each service is responsible for a specific business functionality and can be developed, deployed, and maintained independently. Spring Boot simplifies the development of microservices by providing tools like Spring Cloud and Spring Boot Actuator.

7. How does Spring Boot handle dependency injection?

Dependency Injection (DI) is a key feature of the Spring Framework, and Spring Boot uses it to manage object creation and relationships between objects automatically. In Spring Boot, DI is usually handled through annotations like @Autowired, @Component, and @Service.

8. How can you configure a Spring Boot application?

Spring Boot applications can be configured in multiple ways:

application.properties or application.yml files.

Using the @Configuration classes.

Via command-line arguments.

Environment variables.

9. What are profiles in Spring Boot, and how are they used?

Profiles in Spring Boot allow developers to create different configurations for different environments. For example, you can have one profile for development, one for testing, and one for production. You can specify which profile to use by setting it in the application.properties file or as a command-line argument.

10. What are the limitations of Spring Boot?

Despite its many benefits, Spring Boot has some limitations:

Lack of control over auto-configuration can sometimes lead to unexpected behaviors.

Increased memory usage due to embedded servers.

Limited flexibility in large-scale applications that require extensive custom configuration.

Addressing these limitations demonstrates that you have a well-rounded understanding of the framework and can make informed decisions about when and where to use it.

11. How does Spring Boot handle security?

Spring Boot simplifies security through Spring Security, which can be easily integrated into your application. By adding the spring-boot-starter-security dependency, you can configure authentication and authorization in a few lines of code. You can also customize login, registration, and session management features.

12. What is the role of the Spring Initializr in Spring Boot?

The Spring Initializr is an online tool used to generate Spring Boot projects. It allows developers to choose the dependencies and configuration options before downloading the skeleton code. This tool speeds up the initial setup phase, saving time and effort.

In conclusion, being well-prepared for Spring Boot interviews is crucial, especially in a competitive job market. Whether you're taking a Spring Boot course in Electronic City Bangalore or aiming for Spring Boot Certification Training, knowing these key concepts will give you the edge you need. At eMexo Technologies, you’ll receive hands-on training, not just theory, preparing you to answer interview questions and excel in your career confidently.

Code of Ethics - Ch. 9 - Doing Good vs Doing Well

I'm REALLY liking how this chapter turned out! It has just everything I wanted plus a touching moment that I didn't think I'd be able to put in this early in the story.

Yet another "picks up where the last chapter left off." We'll get to some time skippage again here soon, promise!

Preview below the cut:

Diane shrugged, “Computer, activate the Operations building, please.”

There was the sudden sensation of an almost imperceptible hum as every light, HVAC system, computer, and electrically powered accessory in the building received power all at once. The lights in the office and main Ops room which had been on standby suddenly bloomed with a cool blue light that was bright enough to drive away most shadow but not so bright as to make it difficult to see. Dark paneling that Diane had assumed was simply an interior design choice flickered to life to reveal that they were huge displays that wrapped seamlessly around the entire office that wasn’t a door or window. Startup routines could be seen scrolling up all the displays and, when she looked down, she saw the same was happening on the surface of her desk. Momentarily, a holographic computer interface bloomed to life where she would expect a desktop monitor if she were at an office back ho...er, outside the pod, and a very pleasantly ergonomic keyboard rezzed into place. Oh, nice! I hate touch interfaces for typing, let’s see if... She reached out and tapped a few keys experimentally and, yes, they had the familiar spring-lock feel she preferred in her keyboards.

She smiled and looked up at Katrina, “So, Ops is activated, do we need to wait on anything else to get started with building a ship?”

Katrina raised an eyebrow, almost incredulously, “...no, though I imagine dealing with the squ...” the digital assistant glanced at Norma meaningfully, who for her part just huffed indignantly, “Tenants would take priority.”

“Is getting the ship started going to require more effort than activating Ops?”

“...no...”

Diane smirked, “Computer, begin construction on the Ad Astra based on the available blueprints in station memory.”

One of the wall-displays that had completed its boot-sequence and was on a pleasant screensaver mode flicked over to a visual of a wireframe of a spaceship. It appeared to be a fairly small craft, though obviously intended for long-haul exploration. Callouts appeared for crew quarters, a mess hall, waste recycling, fuel storage, and everything else one might expect of a small expeditionary vessel. The exterior design seemed based on a modified Straczynski-esque craft. Instead of a squat pod that held life-support and an ejectable cockpit, the main body of the ship was somewhat shaped like a ground-transport cargo vehicle, as though someone had taken a semi-truck and attached trailer, fused them into a single piece, modified the front so it looked like a fat sports car, spiffed it up to look like it belonged in space, and then made it big enough to house three to five people and everything they needed to live for long periods of time in the void of space. Attached at the corners starting about one-third of the way back from the nose of the ship were squat ‘wings’ that would never keep the ship in the air in atmosphere. They were in a vague ‘X’ configuration, which would allow for creative use of thrust from the nacelles positioned at the ends of the wings to allow for crazy-fast turns. The nacelles looked like they provided all the thrust to the ship, as well as maneuvering. It’s no Conquistador-class, Diane thought with a smile, But it does look like a sleek little ship. The display popped up with a status bar that was familiar to anyone who had used a computer in the last century and ticked up to the 1% mark after a moment.

“Awesome!” remarked Diane, “So, Katrina, any other immediate tasks? Activating anything else necessary right now?”

“Dealing with the highly annoying tenants?” offered Katrina.

“Oi! You’re the one who’s been sitting on the ability to build a starship the whole time I’ve been trying to deal with the little housing crisis in the residential habs!” snapped Norma.

Katrina glared, for all a tutorial program could glare, at the woman, “You are not authorized users of this system. Had your predecessors left this station as they should have then there wouldn’t be a ‘housing crisis’ in the residential habs.”

“Alright, that’s enough,” said Diane, “Katrina, could you give us the room, please?”

“What?!” the hologram seemed surprised, then collected herself so quickly Diane wondered if she was seeing things, “But…security protocols…”

Diane waved a hand dismissively, “‘Security protocols’ I’m not familiar with and, since I’m the fiat commander of this station, don’t apply to me if I say so.”

“I really should remain present as a precaution in case she…”

Diane huffed, “She’s, what, four feet tall?”

“Five-foot-one!” Norma growled.

“Meanwhile I’m a six-foot-one…”

“Six feet, nine inches,” interrupted Katrina with a significant glare at Norma.

“Sure, that; and I’m an apex predator species, I think I’m more than capable of taking her in a fight if it comes down to it. Besides, you’re a hologram, you can monitor the office via the security systems, right?”

“…yes.”

“Well then, you can give us the illusion of privacy for this conversation and at least take your physical presence out of the room so you stop antagonizing the person I’m trying to…” she glanced at Norma, who’d set her jaw stubbornly, “…have a conversation with.”

Whoever on the dev team programmed the personality of the tutorial program did a damn fine job of making them appear to have emotion as Katrina gave every impression of being hesitant to concede the point as she said, “…very well. If she…causes problems, simply eject her from the office and I’ll seal the doors and flood the Ops command level with a neurotoxin.”

Diane frowned, “A non-lethal neurotoxin, right?”

Katrina seemed to be refusing to meet Diane’s eyes as she started disapperating from the room, “Sure, sure. Non-lethal.” And with that, she was no longer in the room.

Diane allowed a small smile to quirk as she started removing her jacket. Part of it was comfort, part of it was a test. She was deliberately exposing the weapon stuck to her back to Norma. If the woman noticed it, she was either a human player who, for whatever reason, had chosen to take charge of a band of galactic nomads and homeless people, or was a rogue A.I. who was using the cover of being a refuge on an unclaimed station to hide from hunters such as herself. She turned just enough to drape the jacket over the back of her office chair, watching Norma out of the corner of her eye.

No response…let’s see if she’s just faking… As though reaching back to scratch an itch, she palmed the grip of the weapon while using her thumb to “scratch” the nonexistent itchy spot then casually pushed the weapon against her thigh, making it plainly visible as it adhered to her leg like it had her back.

Norma gave no response whatsoever, just sitting down in one of the chairs obviously intended for visitors to the office.

All right, Diane thought as she took her own seat, She’s just an NPC A.I., so no threat here, “So,” she began, “Not to seem like the bad guy, but I this is my station. I get that some of you were born here, but this isn’t 20th century America with a liberal policy that allows illegals to drop a kid and claim backdoor citizenship.”

“… ‘America’…?” Norma said the name of Diane’s home with stark unfamiliarity.

Stifling the frustration that the game creators didn’t bother to give America it’s proper place in history, she simply said, “A country on Earth, predates the period of space exploration and contact with life on other worlds. Point is, I am the law here. It’s my life and safety on the line if I let the lot of you stay and someone turns out to be a bad actor. I’m quite invested in keeping the skin on my back on my back.”

Norma simply glared back at the newly minted station commander.

“What I’m saying,” said Diane into the silence, “Is you will need to sell me on letting you all stay here. As you pointed out, I’ve got a starship under construction,” she glanced at the wall display, Norma mimicking her, and they saw the build progress was now at 2%. “I won’t even need to space you all. I can build a…let’s see here…” she turned to her holographic display and started tapping menues and was pleased to see it was fairly easy to navigate. She found the computer’s storage of ship blueprints and filtered out what the station didn’t have the capability to build yet, then tapped and flicked the plans over to a wall display. “I could build one of these,” the display lit up with a wireframe of another starship, but this was not something sleek and intended for exploration like the Ad Astra, this was a box with an engine strapped to it. The ‘ship’ part was what looked for all the world like a glorified camper van scaled up to house everything necessary to support a barebones crew, in-system flight, and FTL. Attached to that was a comparative behemoth of a cargo container, obviously intended to be modular and detachable. The name attached to the blueprint read, ‘ECC Goldrush.’

“Obviously, we’d have to mod the cargo container, those things are designed to haul materials, not people, and it wouldn’t be comfortable. We probably wouldn’t be able to kit it for gravity and atmosphere control would be…problematic. It would take who knows how long to get to a friendly port…” a notification popped up on her holographic display, blinking a furious red. Her eyebrows scrunched together, she tapped on the notification and saw a message: Katrina - “8 days to nearest Terran Federation station.”

“Katrina, at least pretend this is a private meeting, please…” she muttered, then to Norma said, “About eight days, I guess, to the nearest friendly port.”

The space-born woman frowned at the schematic for the surveyor ship on the wall, her face no longer a mask of anger but now showing muted concern. “I…know some of us would take you up on that. The people who came here on ships that abandoned them, people who had homes and want to go back to them…but,” she turned a pleading look to Diane, “I…I was born here, this is the only home I know!”

So much for the easy solution, Diane thought. She leaned back in her chair and drummed her fingers on the arm rest, letting the silence linger.

6. Handling Facebook User Data

After a successful login, you might want to handle and display user data.

Custom User Service

Create a custom service to process user details.import org.springframework.security.oauth2.core.user.OAuth2User; import org.springframework.security.oauth2.core.user.OAuth2UserAuthority; import org.springframework.security.oauth2.client.userinfo.OAuth2UserService; import org.springframework.security.oauth2.client.oidc.userinfo.OidcUserService; import org.springframework.security.oauth2.core.oidc.user.OidcUser; import org.springframework.security.oauth2.client.userinfo.DefaultOAuth2UserService; import org.springframework.security.oauth2.client.oidc.userinfo.OidcUserRequest; import org.springframework.security.oauth2.client.userinfo.OAuth2UserRequest; import org.springframework.stereotype.Service; import java.util.Map; import java.util.Set; import java.util.HashMap; @Service public class CustomOAuth2UserService implements OAuth2UserService<OAuth2UserRequest, OAuth2User> { private final DefaultOAuth2UserService delegate = new DefaultOAuth2UserService(); @Override public OAuth2User loadUser(OAuth2UserRequest userRequest) { OAuth2User oAuth2User = delegate.loadUser(userRequest); Map<String, Object> attributes = new HashMap<>(oAuth2User.getAttributes()); // Additional processing of attributes if needed return oAuth2User; } }

Controller

Create a controller to handle login and display user info.import org.springframework.security.core.annotation.AuthenticationPrincipal; import org.springframework.security.oauth2.core.user.OAuth2User; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.GetMapping; @Controller public class LoginController { @GetMapping("/login") public String getLoginPage() { return "login"; } @GetMapping("/") public String getIndexPage(Model model, @AuthenticationPrincipal OAuth2User principal) { if (principal != null) { model.addAttribute("name", principal.getAttribute("name")); } return "index"; } }

Thymeleaf Templates

Create Thymeleaf templates for login and index pages.

src/main/resources/templates/login.html

<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <title>Login</title> </head> <body> <h1>Login</h1> <a href="/oauth2/authorization/facebook">Login with Facebook</a> </body> </html>
