[cdi-dev] Dynamic stereotypes

[Mark Struberg]

I have not seen those dynamic stereotypes in free nature yet.

Actually I'm not using Stereotypes that much at all. Mainly because their usage is limited by the Java Annotation boundaries.

Imagine the following Stereotype for my Services (I spare out the standard stuff)


@StereoType
@Secured
@Transactional
@ApplicationScoped
public @interface @Service {}

The problem here is that there is no way to 'propagate' any rolesAllowed from @Service to @Secured, etc.

What I'd like to have is something like
...
public @interface @Service {

    String[] rolesAllowed();
    TransactionAttributeType transactionType();

}

where the rolesAllowed() would get propagated to the @Secured meta-annotation and transactionType() to the @Transactional

With such an annotation I could use:

@Service(rolesAllowed={"admin", "editor"}, transactionType =  REQUIRES_NEW)
public String doSomething() {...



But that's not possible with Java Annotations. Or do you have any ideas how to do that? (without having to manually propagate this in each and every interceptor).
