EJB 3.1 @EJB Injection into POJO

Question

With the new EJB 3.1 spec is it possible to inject an EJB into a pojo? I know in EJB 3.0 the @EJB annotation could be used to inject an EJB but this did not work on simple

Answer 1

I wonder too if I could inject EJBs into unmanaged objects. See the Weld (JSR 299 reference implementation) documentation for more details.

But you can perform dependency injection by hand inside a repository or factory like this:

@Stateless
public PojoRespository {

  @Inject
  ResourceForPojos resource;
  @PersistenceContext
  private EntityManager em;

  public Pojo findById(Object id) {
    Pojo p = (Pojo) em.find(Pojo.class, id);
    p.setResource(resource); // injects resource
    return p;
  }

}

If you have many methods where injection should be performed, you could use an interceptor.
