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! 📈✨

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.

Understanding Spring Framework in Java

With over 650,000 lines of code to understand, it can be difficult for developers to figure out where to begin with this framework. Unlike some other frameworks out there, Java spring framework  does not rely on annotations to define your code's functionality. Instead, you have to use XML files and Plain Old Java Objects (POJO) in order to develop your applications with Java spring Framework 4.0. Java spring framework used by developers as well as organizations to develop and deploy Java applications with a minimum amount of code.
