Create a new Spring Boot project with the necessary dependencies. You can use Spring Initializr or add the dependencies manually to your pom.xml.

Dependencies

<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-security</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-oauth2-client</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> </dependencies>

5. Configuring Spring Security for OAuth2 Login

Next, configure Spring Security to use Facebook for OAuth2 login.

application.properties

Add your Facebook app credentials to src/main/resources/application.properties.spring.security.oauth2.client.registration.facebook.client-id=YOUR_FACEBOOK_APP_ID spring.security.oauth2.client.registration.facebook.client-secret=YOUR_FACEBOOK_APP_SECRET spring.security.oauth2.client.registration.facebook.redirect-uri-template={baseUrl}/login/oauth2/code/{registrationId} spring.security.oauth2.client.registration.facebook.scope=email,public_profile spring.security.oauth2.client.registration.facebook.client-name=Facebook spring.security.oauth2.client.registration.facebook.authorization-grant-type=authorization_code spring.security.oauth2.client.provider.facebook.authorization-uri=https://www.facebook.com/v11.0/dialog/oauth spring.security.oauth2.client.provider.facebook.token-uri=https://graph.facebook.com/v11.0/oauth/access_token spring.security.oauth2.client.provider.facebook.user-info-uri=https://graph.facebook.com/me?fields=id,name,email spring.security.oauth2.client.provider.facebook.user-name-attribute=id

Security Configuration

Create a security configuration class to handle the OAuth2 login.import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.security.config.annotation.web.builders.HttpSecurity; import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity; import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter; import org.springframework.security.oauth2.client.oidc.userinfo.OidcUserService; import org.springframework.security.oauth2.client.userinfo.DefaultOAuth2UserService; import org.springframework.security.oauth2.client.userinfo.OAuth2UserService; import org.springframework.security.oauth2.core.oidc.user.OidcUser; import org.springframework.security.oauth2.core.user.OAuth2User; import org.springframework.security.web.authentication.SimpleUrlAuthenticationFailureHandler; @Configuration @EnableWebSecurity public class SecurityConfig extends WebSecurityConfigurerAdapter { @Override protected void configure(HttpSecurity http) throws Exception { http .authorizeRequests(authorizeRequests -> authorizeRequests .antMatchers("/", "/error", "/webjars/**").permitAll() .anyRequest().authenticated() ) .oauth2Login(oauth2Login -> oauth2Login .loginPage("/login") .userInfoEndpoint(userInfoEndpoint -> userInfoEndpoint .oidcUserService(this.oidcUserService()) .userService(this.oAuth2UserService()) ) .failureHandler(new SimpleUrlAuthenticationFailureHandler()) ); } private OAuth2UserService<OidcUserRequest, OidcUser> oidcUserService() { final OidcUserService delegate = new OidcUserService(); return (userRequest) -> { OidcUser oidcUser = delegate.loadUser(userRequest); // Custom logic here return oidcUser; }; } private OAuth2UserService<OAuth2UserRequest, OAuth2User> oAuth2UserService() { final DefaultOAuth2UserService delegate = new DefaultOAuth2UserService(); return (userRequest) -> { OAuth2User oAuth2User = delegate.loadUser(userRequest); // Custom logic here return oAuth2User; }; } }

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>

src/main/resources/templates/index.html

<!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org"> <head> <title>Home</title> </head> <body> <h1>Home</h1> <div th:if="${name}"> <p>Welcome, <span th:text="${name}">User</span>!</p> </div> <div th:if="${!name}"> <p>Please <a href="/login">log in</a>.</p> </div> </body> </html>

How to Make the Most of Online Java Training Resources

In today’s digital age, learning Java has become more accessible than ever, thanks to a variety of virtual learning platforms. Whether you're a student, working professional, or career changer, you can harness the power of online education to gain strong programming skills. The key lies in how effectively you use the available resources. With so many platforms offering online java training, it’s essential to develop a smart learning strategy that combines structure, practice, and support.

Identify the Right Platform

Not all training platforms are created equal. Some are known for their structured syllabus, while others focus on peer interaction or mentor support. It’s crucial to choose a platform that fits your learning style. Look for reviews, trial classes, and course outlines. A good platform should cover both basic and advanced Java topics such as object-oriented programming, collections, multithreading, JDBC, and frameworks like Spring and Hibernate.

Build a Custom Learning Schedule

Online learning offers flexibility, but that freedom also demands discipline. Begin by setting achievable goals and timelines. Divide your syllabus into manageable parts and allocate specific hours each day or week for studying. Use tools like planners or calendar apps to maintain consistency. Staying organized will keep you from getting overwhelmed and will help you make steady progress.

Combine Theory with Practical Coding

Merely watching tutorials or reading documents isn't enough to master Java. As you learn new concepts, immediately apply them by writing and testing code. Utilize integrated development environments (IDEs) like IntelliJ IDEA or Eclipse to practice. Many online platforms provide coding sandboxes or project builders—take full advantage of these to deepen your understanding.

Participate in Challenges and Projects

One of the most effective ways to solidify your learning is by taking part in real-world projects and coding challenges. Websites like HackerRank, LeetCode, and CodeChef host Java coding problems ranging from beginner to advanced levels. These platforms help improve your logical thinking and problem-solving skills, which are crucial for job readiness.

Join Peer and Mentor Communities

The online learning journey can sometimes feel isolating, but it doesn’t have to be. Engage with fellow learners through forums, Discord groups, or platform-specific communities. Ask questions, participate in discussions, and share your code. Some platforms also offer mentorship programs, connecting you with experienced professionals who can guide your progress.

Focus on Core Concepts Before Advanced Topics

It’s tempting to jump straight into popular frameworks like Spring Boot or Hibernate, but without a solid understanding of core Java, it’s easy to get lost. Spend ample time on fundamentals such as variables, loops, conditionals, arrays, and OOP principles. Once these are second nature, transitioning into advanced topics becomes smoother and more productive.

Keep Learning Interactive and Fun

Monotony can kill motivation. Keep things interesting by mixing up your learning resources. Alternate between video lectures, articles, coding exercises, and podcasts. You can even join virtual study groups or attend live webinars to break the routine and get fresh perspectives.

Take Notes and Document Your Learning

Maintaining a digital or handwritten notebook can significantly boost your retention. Jot down code snippets, commands, and key takeaways from each lesson. These notes will serve as a quick reference guide when you start working on projects or preparing for interviews.

Evaluate Progress Through Mock Tests

Most online platforms offer quizzes and mock tests—don’t skip them. These tests not only reinforce what you’ve learned but also help you identify weak areas. Regular assessments are a great way to measure your improvement and build confidence.

Explore Integration with Other Skills

Once you’re comfortable with Java, explore how it connects with other domains like databases, front-end development, or mobile app development. Expanding your skill set adds value to your profile and opens up broader career opportunities.

Platforms like Traininglobe provide well-structured Java learning paths that include hands-on assignments and industry-relevant projects, which enhance your portfolio and improve your job prospects.

Application in Related Fields

As you grow more confident with Java, it's helpful to understand how coding skills apply in broader tech fields. For instance, designing responsive web applications often involves a cross-functional approach. Understanding technologies tied to courses website design gives you a full-stack perspective and increases your versatility as a developer.

Conclusion

Online Java training resources offer more than just convenience—they offer a personalized and rich learning experience. The trick to getting the most from these resources lies in setting clear goals, staying consistent, engaging with communities, and applying what you learn. By combining self-discipline with interactive tools and expert guidance, you can build a solid foundation in Java programming and confidently move toward your career goals. Keep exploring, stay curious, and let your journey with Java be as dynamic as the language itself.

Java Full Stack vs. Python Full Stack: My Journey Choosing One

Back when I was figuring out my path as a coder, I spent countless evenings at a tiny tea stall near my apartment in Pune, scribbling notes about whether to go all-in on Java or Python for full stack development. It felt like choosing between two best friends—one steady and reliable, the other quick and fun. Both could help me build websites from the flashy front end to the gritty back end, but they had such different flavors. If you’re standing at the same crossroads, wondering whether Java full stack or Python full stack is your vibe, let me walk you through what I learned, like we’re chatting over a cup of chai. This is about what each path feels like, how they work, and what they mean for your coding life.

Java and Python both let you do this, but they’re like cooking with different spices. Java’s the old-school chef, meticulous and trusted by big restaurants. Python’s the trendy food truck cook, whipping up dishes fast and winning fans with ease. I remember my first gig at a small tech firm, where I had to pick one to build a client’s app. That choice shaped how I saw these two worlds.

Java full stack felt like stepping into a well-oiled machine. Java’s been around forever, powering huge systems like bank apps or online stores. For the front end, you’d use something like React or Angular, which are JavaScript-based, but Java takes over on the back end with Spring Boot. I worked on a project for a logistics company, using Spring Boot to connect a user-friendly dashboard to a database tracking shipments. Setting it up was like assembling a complicated LEGO set—lots of pieces to snap together, like configuration files and dependency setups. Java’s strict rules, like spelling out every variable’s type, made me slow down and think, but that rigor meant our app could handle thousands of users without crashing. It’s a favorite in places like finance or government, where things can’t afford to break.

Python full stack, though, was like cooking with a recipe that just clicks. Python’s so easy to read, it’s like writing a letter. On the back end, you’d use Django or Flask, which are like cheat codes for building apps fast. I helped a friend’s startup build a booking app with Django, and we had a working prototype in days. Django gave us pre-built tools for user logins and database connections, so we could focus on making the app look good. Like Java, you’d pair it with JavaScript for the front end. Python’s perfect for startups or projects tied to data crunching, like apps that use AI to recommend products. The downside? It’s not as speedy for massive systems, so if you’re building the next Amazon, it might struggle.

The tools you use show how different these paths are. With Java, I was glued to IntelliJ, an IDE that felt like a spaceship control panel, and Spring Boot for back-end logic. We used Maven to keep track of all the libraries we needed, which was handy but felt like paperwork. Python was simpler. I’d fire up VS Code, a lightweight editor, and use Django with pip to grab packages. Java’s setup took time, like prepping a gourmet meal. Python let me jump straight to coding, like tossing ingredients into a stir-fry.

Learning each one was its own adventure. Java was tough at first. I’d groan at writing long chunks of code just to do simple things, like connecting to a database. But that structure taught me discipline, which paid off when I joined a big team where everyone had to sync up. Python was a joy to learn. I’d write a few lines, and boom, something worked. It felt like magic, especially for small projects at places like Technoscripts, where you’re churning out prototypes. But Python’s looseness meant I had to be careful not to write messy code that’d haunt me later.

Jobs-wise, both are gold in 2025. Java full stack devs are snapped up by big firms—think Wipro or Accenture—building systems that need to last decades. In India, freshers might earn ₹5-10 lakh a year, more in the U.S. Python full stack devs shine in startups or tech-driven companies like Flipkart, especially for AI or data-heavy apps. Salaries are close, maybe ₹4-9 lakh for beginners. Java’s strength is its grip on corporate giants; Python’s is its speed and AI edge.

So, which did I pick? I started with Python because it got me coding fast and felt less intimidating. Later, I learned Java to tackle bigger projects. If you want to build bulletproof systems and don’t mind a challenge, go Java. If you love moving quick and dreaming up cool apps, Python’s your friend. Either way, you’re building the web’s future, and that’s pretty darn exciting.

4. Create a REST Controller

Spring Boot uses the @RestController annotation to create API endpoints.package com.example.restapi.controller;import com.example.restapi.model.Employee; import org.springframework.web.bind.annotation.*;import java.util.ArrayList; import java.util.List;@RestController @RequestMapping("/employees") public class EmployeeController { private List<Employee> employees = new ArrayList<>(); @GetMapping public List<Employee> getAllEmployees() { return employees; } @PostMapping public Employee addEmployee(@RequestBody Employee employee) { employees.add(employee); return employee; } @GetMapping("/{id}") public Employee getEmployeeById(@PathVariable Long id) { return employees.stream() .filter(emp -> emp.getId().equals(id)) .findFirst() .orElse(null); } @DeleteMapping("/{id}") public String deleteEmployee(@PathVariable Long id) { employees.removeIf(emp -> emp.getId().equals(id)); return "Employee removed."; } }

5. Run and Test the API

Start the application by running the RestApiApplication.java class. You can test the API using Postman or cURL.

GET all employees: GET http://localhost:8080/employees

POST a new employee: POST http://localhost:8080/employees

Request Body (JSON):

json

{ "id": 1, "name": "John Doe", "department": "IT" }

GET employee by ID: GET http://localhost:8080/employees/1

DELETE an employee: DELETE http://localhost:8080/employees/1

6. Enhancements
