WELD-001409不明确的依赖关系 [英] WELD-001409 Ambiguous dependencies

问题描述

我想将我的ejbProfileEJB注入我的jsf托管beanSampleController，如下所示：

I want to inject my ejb "ProfileEJB" into my jsf managed bean "SampleController" like so:

@Stateless
@LocalBean
public class ProfileEJB {

    @PersistenceContext
    private EntityManager em;

    public Profile create(Profile p) {
        em.persist(p);
        return p;
    }

}

SampleController：

SampleController:

@Named(value = "sampleController")
@ViewScoped
public class SampleController {

    @Inject
    private ProfileEJB profileBean;

    public SampleController() {
    }

}

问题是我收到以下错误：

The problem is i get the following error:

CDI deployment failure:WELD-001409 Ambiguous dependencies for type [ProfileEJB] with qualifiers [@Default] at injection point [[BackedAnnotatedField] @Inject private com.example.controller.SampleController.profileBean]. Possible dependencies [[Session bean [class com.example.ejb.ProfileEJB with qualifiers [@Any @Default]; local interfaces are [ProfileEJB], Session bean [class com.example.ejb.ProfileEJB with qualifiers [@Any @Default]; local interfaces are [ProfileEJB]]]

我可以从消息中了解到有两个相同的bean和它不能决定注入哪些，但我不知道为什么有两个相同的豆？有人可以向我解释一下吗？
非常感谢！

I can understand from the message that there are two same beans and it cannot decide which to inject but i don´t know why there are two same beans? Can someone please explain it to me? Thank your very much!
