我想部署我在JBoss战争档案，但我得到这个错误：

我尝试谷歌它和解决它在互联网相同的错误解决方案，但我无法修复它。我越来越多地得到这个错误。

我的DAO接口：

/** 
* @Author is flystyle 
* Created on 05.06.16. 
*/ 
public interface IRequestDAO { 
    Integer createRequest(final Request source); 
    List<Request> list(final Date date); 
    List<Request> list(); 
    List<Request> list(final Station begin, final Station end); 
    Request getRequestById (final int id); 
    List<Request> getRequestsByUserId (final int userId); 

    void removeRequestById(final int id); 
    void removeRequestByUser(final User user); 

    @Deprecated 
    void removeAllRequests(); 

} 

我的UserDAO类：

@Stateless // look I have this annootation! 
public class UserDAO implements IUserDAO { 

    private SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory(); 

    public User verifyEnter(String name, String pass) { 
     Session session = sessionFactory.openSession(); 
     Transaction tr = null; 
     tr = session.beginTransaction(); 

     String sql = "SELECT * FROM rails_user WHERE user_name = :an AND user_pass = :ap"; 
     SQLQuery query = session.createSQLQuery(sql); 
     query.addEntity(User.class); 
     query.setParameter("an", name); 
     query.setParameter("ap", pass); 
     User res = (User) query.uniqueResult(); 
     tr.commit(); 
     session.close(); 
     return res; 
    } 

    public Admin adminEnter(String name, String pass) { 
     Session session = sessionFactory.openSession(); 
     Transaction tr = null; 
     tr = session.beginTransaction(); 

     String sql = "SELECT * FROM rails_admin WHERE admin_name = :an AND admin_pass = :ap"; 
     SQLQuery query = session.createSQLQuery(sql); 
     query.addEntity(Admin.class); 
     query.setParameter("an", name); 
     query.setParameter("ap", pass); 
     Admin res = (Admin) query.uniqueResult(); 
     tr.commit(); 
     session.close(); 
     return res; 
    } 

    public Integer register(String name, String surname, String pass) { 
     Session session = sessionFactory.openSession(); 
     Transaction transaction = null; 
     transaction = session.beginTransaction(); 
     User user = new User(); 
     user.setName(name); 
     user.setSurname(surname); 
     user.setPass(pass); 
     Integer id = (Integer) session.save(user); 
     transaction.commit(); 
     session.close(); 
     return id; 
    } 

    public List getAllUsers() { 
     Session session = sessionFactory.openSession(); 
     Transaction tr = null; 
     tr = session.beginTransaction(); 

     String sql = "SELECT * FROM rails_user"; 
     SQLQuery query = session.createSQLQuery(sql); 
     query.addEntity(User.class); 
     List res = query.list(); 
     tr.commit(); 
     session.close(); 
     return res; 
    } 

    public User getUserById(int id) { 
     Session session = sessionFactory.openSession(); 
     Transaction tr = null; 
     tr = session.beginTransaction(); 

     String sql = "SELECT * FROM rails_user WHERE user_id = :id"; 
     SQLQuery query = session.createSQLQuery(sql); 
     query.addEntity(User.class); 
     query.setParameter("id", id); 
     User res = (User) query.uniqueResult(); 
     tr.commit(); 
     session.close(); 
     return res; 
    } 

    public void banUser(int id) { 
     Session session = sessionFactory.openSession(); 
     SQLQuery q = session.createSQLQuery("DELETE FROM rails_user WHERE request_id = :id"); 
     q.addEntity(User.class); 
     q.setParameter("id", id); 
     q.executeUpdate(); 
    } 

    public boolean verifyAdminEnter(String name, String pass) { 
     Session session = sessionFactory.openSession(); 
     Transaction tr = null; 
     tr = session.beginTransaction(); 

     String sql = "SELECT * FROM rails_admin WHERE admin_name = :an AND admin_pass = :ap"; 
     SQLQuery query = session.createSQLQuery(sql); 
     query.addEntity(Admin.class); 
     query.setParameter("an", name); 
     query.setParameter("ap", pass); 
     Admin res = (Admin) query.uniqueResult(); 
     tr.commit(); 
     session.close(); 
     if (res.getName().equals(name) && res.getPass().equals(pass)) 
      return true; 
     return false; 
    } 

} 

我联系Controller类：

@ManagedBean(name = "rails_admin_panel") 
@SessionScoped 
public class AdminPanelController implements AdminAction{ 

    private List<User> allUsers; 
    private List<Request> allRequests; 

    @EJB 
    private UserDAO userDAO = new UserDAO(); 
    @EJB 
    private RequestDAO requestDAO = new RequestDAO(); 

    public void viewAllUsers() { 
     allUsers = userDAO.getAllUsers(); 
    } 

    public void viewAllRequests() { 
     allRequests = requestDAO.list(); 
    } 

    public void deleteRequest(int id) { 
     requestDAO.removeRequestById(id); 
    } 

    public void deleteUser(int id) { 
     userDAO.banUser(id); 
    } 

    public List<Request> getAllRequests() { 
     return allRequests; 
    } 

    public List<User> getAllUsers() { 
     return allUsers; 
    } 
} 

你能帮助我吗？

在启动应用程序服务器期间无法找到接口pro.alexfly.lab4.dao.UserDAO，因为您没有人。要解决这个问题：

• 尝试使用您接口IUserDAO这里：

@EJB 
private UserDAO userDAO = new UserDAO(); 

• 不要手动创建您自己的情况下，应该通过JBoss容器注入。
• 检查您的接口是否有@Local注释。
