🌱 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! 📈✨
