Difference between @Component, @Service, and @Repository Annotations in Spring Framework

In Spring framework, the @Component, @Service, and @Repository annotations are used to define Spring beans with specific functionalities:

  • @Component: This annotation is a generic stereotype annotation used for any Spring-managed component. It indicates that a particular class is a Spring component.
  • @Service: This annotation is used to annotate classes at the service layer. It indicates that the class defines a service.
  • @Repository: This annotation is used to annotate classes at the persistence layer, which could be DAOs or repositories. It indicates that the class deals with database operations.

The main difference lies in their intended use cases within the Spring framework. While @Component is a generic annotation, @Service and @Repository provide more specific functionality and semantic meaning to the classes they annotate.
