Yes, in Spring, you can use the @Component annotation instead of @Service to define beans, as @Service is a specialized form of @Component.

The @Service annotation is used for semantic marking of classes that implement business logic, which helps improve code readability and maintainability. However, in terms of functionality, both options create beans and register them in the Spring context.

Example:

@Component
public class MyService {
    // business logic
}

or

@Service
public class MyService {
    // business logic
}

Both options will work equally, but using @Service is preferable for business logic classes, as it enhances semantics and can be useful for aspect-oriented programming (e.g., for automatic transaction application).
