我正在使用Netbeans 7.3.1
在Havnate中使用Javafx开发简单的Application在小项目中，我使用Wizards Setup连接了hibernate。我想使用hibernate在TableView中显示公司表数据。但是，当我运行此应用程序时，它显示以下错误消息：
INFO: building session factory

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

我在Simple Swing应用程序中尝试过相同的Hibernate连接正常工作，但是使用javafx它会显示上面列出的麻烦。
答案 0 :(得分：0)
我没有使用HibernateUtil类
就这样做了您可以通过以下代码获取会话。这是我的控制器部分。而且对我来说工人很好
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();
}
