Master Spring IoC
Learn Spring Inversion of Control (IoC) to build loosely coupled, scalable, and maintainable Java applications using dependency injection.
Go To Spring(MVC)->Why Learn Spring IoC?
Loose Coupling
Spring manages object creation and dependencies automatically.
Dependency Injection
Inject required objects using constructor, setter, or annotations.
Easy Management
Beans are centrally configured and managed inside the Spring container.
Core Concepts
Basic Example
@Component
class Engine {}
@Component
class Car {
@Autowired
Engine engine;
}
Annotations
- @Component
