對不起，我有一個與cdi 1.0，deltaspike 0.5和primefaces 4.0的戰爭項目，當我試圖使用@Respository與@EntityManagerConfig，因爲我有兩個生產對EntityManager的使用diferent @Qualifiers，我使用應用服務器GlassFish的4這是庫德代碼，生產和EntityManagerResolver：deltaspike存儲庫entitymanagerresolver錯誤與兩個產生entityManger
庫：
@Repository(forEntity = User.class)
@EntityManagerConfig(entityManagerResolver = HbsWebEntityManagerResolver.class, flushMode = FlushModeType.AUTO)
public abstract class UserRepository extends
AbstractEntityRepository<User, Integer> {
@Query(named = User.BY_LOGIN)
public abstract User findByLoginEqual(@QueryParam("login") String login);
}
EntityManagerResolver：
public class HbsWebEntityManagerResolver implements EntityManagerResolver{
@Inject
@HbsWeb
private EntityManager hbsWebEntityManager;
@Override
public EntityManager resolveEntityManager() {
return hbsWebEntityManager;
}
}
產地：
@ApplicationScoped
public class EntityManagerProducer {
@PersistenceUnit(unitName="HBS")
private EntityManagerFactory hbsEntityManager;
@PersistenceUnit(unitName="HBSWEB")
private EntityManagerFactory hbsWebEntityManager;
@Produces
@Hbs
protected EntityManager createHbsEntityManager() {
return hbsEntityManager.createEntityManager();
}
protected void closeHbsEntityManager(
@Disposes @Hbs EntityManager entityManager) {
if (entityManager.isOpen()) {
entityManager.close();
}
}
@Produces
@HbsWeb
protected EntityManager createHbsWebEntityManager() {
return hbsWebEntityManager.createEntityManager();
}
protected void closeHbsWebEntityManager(
@Disposes @HbsWeb EntityManager entityManager) {
if (entityManager.isOpen()) {
entityManager.close();
}
}
}
當我嘗試使用與存儲庫@Inject我得到了如下錯誤：

有誰知道爲什麼這個錯誤發生？
