Hibernate Session не открыт с помощью JavaFX

Question

Я занимаюсь разработкой простого приложения в JavaFX с Hibernate с использованием Netbeans 7.3.1

В небольшом проекте я подключен в спящем режиме с помощью программы установки Мастера. Я хочу показать данные таблицы компании в TableView, используя спящий режим. Но когда я запускаю это приложение, он показывает сообщение об ошибке ниже:

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

Используя приведенный ниже код, я хочу, чтобы получить данные:

@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(); 
    } 
} 

Это исключение генерируется:

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

Выход Вход:

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)" 

Я попробовал то же самое в простой приложений Swing там связность Hibernate работает нормально, но с помощью JavaFX это показывает проблемы вышеперечисленное.

Answer 1

Спящий режим в JavaFx совместим с версией NetBeans 7.4. Версия NetBeans версии 7.3 или ниже не подходит для JavaFx.

Вместо использования мастера обратного проектирования. вы можете легко работать с файлами POJO и отображения.

Answer 2

Я сделал это без использования класса HibernateUtil

вы можете получить сеанс с помощью следующего кода. это моя часть контроллера. и это рабочий штраф для меня

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(); 
     }
