无法创建sessionfactory：annotationConfiguration实例是必需的

标签： hibernate exception gwt rpc sessionfactory

我无法让我的hibernate函数（例如getusers（））在RPC实现中工作（例如在login（）中）。

我把所有的hibernate函数放到服务器上的dataServiceImpl类中，但是当我有一个自己的类函数并运行它作为普通的java应用程序时，它工作正常，所以我不知道为什么我不能使用相同的在我的rpc funkctions中。

在我的RPC登录功能中，我尝试使用以下测试：

List<User> userlist = getUsers();
        Window.alert(userlist.toString());

这里的getusers功能：

public List<User> getUsers(){
        try{
             Configuration configuration = new Configuration();
             configuration.configure("/swmhibernate.cfg.xml");
             ServiceRegistry serviceRegistry = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties()).build();
             factory = configuration.buildSessionFactory(serviceRegistry); }
            //factory = new Configuration().configure("swmhibernate.cfg.xml").buildSessionFactory();}
         catch (Throwable ex) { 
            System.err.println("Failed to create sessionFactory object." + ex);
            throw new ExceptionInInitializerError(ex); 

         }

         Session session= factory.openSession();
         Transaction tx = null;
         List <User> users=new ArrayList<User>();
         try{

             tx = session.beginTransaction();
            users=session.createCriteria(User.class).list();
             Query q= session.createQuery("select u from User u");
             List<User> u1=q.list();

             System.out.println("data loaded here");
             for(User u2:u1){
                 if(u2.getCustomerList().size()>1)
                 {System.out.println(u2.getUserid()+ "  ADDED USER");
                 users.add(u2);
                 }
             }
         }catch (RuntimeException e) {
              if (tx != null && tx.isActive()) {
                    try {
            // Second try catch as the rollback could fail as well
                      tx.rollback();
                    } catch (HibernateException e1) {
                      e1.printStackTrace();
                    }
            // throw again the first exception
                    throw e;
                  }
                }finally{session.close();}
         return users;
     }

swmhibernate.cfg.xml：

我希望有人可以提供帮助， 谢谢realizze

编辑我删除了一些.jar文件，现在出现了同样的错误，但其原因是：

1 个答案:

答案 0 :(得分：0)

现在我解决了这个问题。如果你使用hibernate版本4.1.0而不是hibernate4.3.5就没有问题了。
