  • @Component vs @Service

    Hi Guys,

    I have a simple question about annotations @Component and @Service.

    What is the difference between them, and what exactly @Service mean ? how I understand they both register a Component as Bean in Spring Context ..

    and also can anybody provide me with example of creating/using/registering nice "Services" with @Service

    Thank you

    My understanding is that

    - @Component indicates any Spring-managed component, whereas

    - @Service is a specialisation of @Component to indicate a component in your service layer.

    Other specialisations of @Component are

    - @Repository to indicate a DAO
    - @Controller in the presentation layer

    I don't think there's much practical difference between these - but perhaps in exception translation, or if you were to write your own AOP interceptors to handle them differently.

    The relevant section of the Reference Guide is Section 3.

      Check this section of the Spring reference guide.

      The best way to get a good response to your question is to post in the right forum. Although you may be using Spring Web Flow, you're more likely to get a helpful response in the core container forum.
