What's the difference between @Component, @Repository & @Service annotations in Spring?

Question

Can @Component, @Repository and @Service annotations be used interchangeably in Spring or do they provide any particular functionality besides acting as a notation device?

Answer 1

@Repository @Service and @Controller are serves as specialization of @Component for more specific use on that basis you can replace @Service to @Component but in this case you loose the specialization.

1. **@Repository**   - Automatic exception translation in your persistence layer.
2. **@Service**      - It indicates that the annotated class is providing a business service to other layers within the application.
