我的目标是验证EJB(DAO)中的类可以接收到EntityManager的注入.

SessionBean EJB的模式不是很棒,但是我必须修改已经创建的应用程序,所以我没有太多的选择.

这是我的EJB代码：

@Named
public class DAOTest implements Serializable {
    private static final long serialVersionUID = 1L;

    @PersistenceContext(unitName="CDI-ejb")
    private EntityManager em;

    public void test(){
        //em.getClass();
    }


    public EntityManager getEm() {
       return em;
    }


    public void setEm(EntityManager em) {
        this.em = em;
    }

    public DAOTest() {
        // TODO Auto-generated constructor stub
    }

}

Service.java

@Stateless
@LocalBean
public class Service implements ServiceLocal {

    @Inject DAOTest test;
    /**
    * Default constructor. 
    */
    public Service() {
        // TODO Auto-generated constructor stub
    }


    @Override
    public void test() {
        test.test();

    }


}

和ServiceLocal.java

@Local
public interface ServiceLocal {
    void test();
}

在我的战争中

@WebServlet("/Test")
public class Test extends HttpServlet {
    private static final long serialVersionUID = 1L;
    @Inject private ServiceLocal service;

    /**
    * @see HttpServlet#HttpServlet()
    */
    public Test() {
        super();
        // TODO Auto-generated constructor stub
    }


    /**
    * @see HttpServlet#doGet(HttpServletRequest request,HttpServletResponse response)
    */
    protected void doGet(HttpServletRequest request,HttpServletResponse response) throws ServletException,IOException {
        service.test();
    }


    /**
    * @see HttpServlet#doPost(HttpServletRequest request,HttpServletResponse response)
    */
    protected void doPost(HttpServletRequest request,IOException {
        // TODO Auto-generated method stub
    }


 }

我通过使用@ Stateless注释来对DAOTest进行了注释.一切都应该发生.所以CDI运作良好但是只要@命名它不想工作.

任何想法？

堆栈跟踪：
