    @Repository is a specialization of @Component

    @Repository is used to mark classes that has the role of a repository (like the DAO)
    the use of this marker is the automatic traslation of exception
    (try to look in the official documentation the "Exception Traslation"
    http://static.springsource.org/sprin...on-translation)

    @Component is only the more generic stereotype for any Spring managed component

    Therefor you can annotate your class with @component, but annotating with the more specific marker (@Repository,@Component,@Service,@Controller), your classes are more properly suited for processing by tool or associating with aspect
