Answer from AI

The @Component annotation in Spring is used to mark a class as a component that should be automatically detected and registered in the Spring context as a bean. This allows Spring to manage the lifecycle of the object, inject dependencies, and use it in other parts of the application.

Example:

@Component
public class UserService {
    // business logic
}

When Spring scans the classes, it will find this class and create an instance of it, which can be injected via @Autowired.

Thus, @Component serves as a basic annotation for creating managed Spring components.
