How can I inject two EJBs of same type?

问题

I'm trying to inject two EJBs of same type with different annotation. But the instances injected are same.

@Path("/some")
public class SomeResource {

    @Inject
    @SomePostConstructionAnnotationForSomeService("this")
    private SomeService s1;

    @Inject
    @SomePostConstructionAnnotationForSomeService("that")
    private SomeService s2;
}

SomeService class looks like this.

public SomeService {

    @PostConstruct
    private void constructed() {
        // find the annotation and do something else.
    }

    @Inject
    private InjectionPoint injectionPoint;
}

The problem is that only s1 is invoked and s2 is equals s1.

回答1:

This will work if SomeService is CDI bean and its scope is @Dependent or no scope (that also means @Dependent when injected into another bean). What scope does it have? If SomeService is EJB bean not CDI this won't work.

UPDATE: You could move SomeService to a base class and create two different EJB beans by extending this class and inject these EJBs.
