Do you apply the @Component annotation when declaring classes as beans in Spring?

Yes, the @Component annotation in Spring is used to mark a class as a component that will be automatically detected and registered in the Spring context as a bean.

However, more specialized annotations are often used, which are derived from @Component:

@Service — for service classes,
@Repository — for data access classes,
@Controller — for MVC controllers.

Using @Component is justified when the class does not fit more specific stereotypes or for creating custom components.

Example:

import org.springframework.stereotype.Component;

@Component
public class MyBean {
    // class logic
}

Thus, @Component is a basic annotation for bean registration, but in practice, it is often preferable to use more specific annotations.
