Dependency injection in Spring

🌱 Master Dependency Injection in Spring 🌱

🔹 What is Dependency Injection (DI)? Dependency Injection (DI) in Spring is a design pattern that allows us to inject dependencies into a class rather than create them within the class, promoting loose coupling and easier testing.

🔹 How DI Works in Spring: Spring IoC (Inversion of Control) container handles DI by managing beans and their lifecycle. It injects dependencies using:

Constructor Injection

Setter Injection

Field Injection

🔹 Advantages:

Simplifies testing

Enhances code reusability

Promotes modular architecture

With DI, you can focus on building cleaner, more maintainable applications! 📈✨

How Spring Security Protects Your Web Application

Spring Security is a powerful and customizable framework for securing web applications in the Spring ecosystem. Here’s how it safeguards your application:

1️⃣ Authentication: Verifies user identities through login forms, HTTP basic authentication, OAuth2, and more.

2️⃣ Authorization: Controls user access with roles and permissions, defining who can access which parts of the application.

3️⃣ Protection Against CSRF: Cross-Site Request Forgery (CSRF) attacks are prevented by validating tokens in requests.

4️⃣ Session Management: Manages user sessions securely, limiting vulnerabilities like session fixation.

5️⃣ Password Encoding: Encrypts passwords using algorithms like bcrypt, preventing plain-text storage.

6️⃣ Security Headers: Adds default security headers (X-Content-Type, X-Frame-Options, etc.) to secure requests and responses.

7️⃣ OAuth2 and JWT Support: Enables integration with OAuth2 for secure SSO and JWT for stateless session handling.

Secure your application effectively with Spring Security – customizable, reliable, and robust!

🚀 Take your skills to the next level with Spring Online Training for comprehensive, hands-on learning in Spring Security, Spring Boot, and more!

CRaC (Coordinated Restore at Checkpoint) is supported in SpringFramework 6.1

By the way, are you familiar with CRaC? CRaC is "Coordinated Restore at Checkpoint". Literally, CRaC takes a snapshot of the Java process when it is fully warmed up, then uses that snapshot to launch any number of JVMs from this captured state.

Why CRaC is needed?

When the application starts running, the JVM looks for methods that are hotspots and compiles them for better performance than interpreting bytecode. This results in fast, optimized code, but has the drawback that the JVM decides which methods to compile and requires both time and computational resources to compile them. This is what is known as the warm-up time of the application. The fact that this same work must be done each time the application is run makes the JVM less attractive in certain situations, such as Microservices and Serverless computing. That is where CRaC comes in. CRaC enables you to store the state of an application itself, to reduce the required time to load data and initialize the required structures. This is achieved by using a "Checkpoint / Restore" approach.

What is Checkpoint / Restore ?

Checkpoint/Restore allows a running application to be paused and resumed from one point in time on a different machine. When performing a checkpoint, essentially the complete context of the process is preserved: program counters, registers, stacks, memory mapped memory, shared memory, etc. To restore the application, all this data can be reloaded and (theoretically) continue from the same point.
