我正在使用 Netbeans 7.3.1 使用 Hibernate 在 Javafx 中开发简单的应用程序

在这个小项目中，我使用 Wizards Setup 连接了休眠。我想使用休眠在 TableView 中显示公司表数据。但是当我运行这个应用程序时，它会显示以下错误消息：

    INFO: building session factory
    Initial SessionFactory creation failed.net.sf.cglib.core.CodeGenerationException:     
    java.lang.reflect.InvocationTargetException-->null
    java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

    (EventHandlerManager.java:170)

我有以下文件：

使用下面的代码，我想获取数据：

@FXML   
void initialize() {
    assert btnQuery != null : "fx:id=\"btnQuery\" was not injected: check your 
      FXML  file 'testing.fxml'.";
    assert tableview != null : "fx:id=\"tableview\" was not injected: check your 
      FXML file 'testing.fxml'.";
    assert txtName != null : "fx:id=\"txtName\" was not injected: check your 
      FXML file 'testing.fxml'.";
}
private String QUERY_ALL = "from Company";

@FXML
void btnQueryClick(ActionEvent event) {
    executeHQLQuery(QUERY_ALL);
}

private void executeHQLQuery(String hql) {

    try {

        Session session = HibernateUtil.getSessionFactory().openSession();
        session.beginTransaction();
        Query q = session.createQuery(hql);   
        System.out.println(hql);
        List resultList = q.list();            
        displayResult(resultList);
        session.getTransaction().commit();
    } catch (HibernateException he) {
        he.printStackTrace();
    }
}

这是生成的异常：

  Session session = HibernateUtil.getSessionFactory().openSession();

日志输出：

INFO: building session factory Initial SessionFactory creation failed.net.sf.cglib.core.CodeGenerationException:
   java.lang.reflect.InvocationTargetException-->null

   java.lang.RuntimeException: java.lang.reflect.InvocationTargetException
at javafx.fxml.FXMLLoader$ControllerMethodEventHandler.handle
      (FXMLLoader.java:1440)"

我在一个简单的 Swing 应用程序中尝试了同样的方法，Hibernate 连接工作正常，但是使用 javafx 它显示了上面列出的问题。

我没有使用 HibernateUtil 类就做到了

您可以通过以下代码获取会话。这是我的控制器部分。它对我来说很好

Session session = null;
        Transaction tx = null;
        SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
List<Sample> results = null;

        try {

            session = sessionFactory.openSession();
            tx = session.beginTransaction();
            Criteria cr = session.createCriteria(Sample.class);
            //cr.add(Restrictions.eq("qualification", "yes"));
            results = cr.list();
            tx.commit();
        } catch (Exception e) {
            e.printStackTrace();
            tx.rollback();
        }

JavaFx 中的 Hibernate 与 NetBeans 7.4 版本兼容。NetBeans 7.3 或更低版本不适合 JavaFx。

而不是利用逆向工程向导。您可以轻松地使用 POJO 和映射文件。
