为什么我的(春季)HibernateTransactionManager不在wicket工作?

我正在转换一个小的 要使用的web应用程序 小门+春天+冬眠 . 我有一个DAO服务类,带有一个由Spring注入的hibernate SessionFactory。我可以使用会话工厂执行只读操作(默认情况下,autocommit处于启用状态)。我要做的是使用HibernateTransactionManager和@Transactional注释来执行事务操作。

我定义了一个DAO服务实现,它在标记为@Transactional的方法中使用注入的SessionFactory:

public class DAO implements IDAO {
 @SpringBean
 private SessionFactory sessionFactory;

 public DAO() {
  super();
 }

 @Transactional
 public Object execute(SessionUnit sessionUnit) {
  Session sess = sessionFactory.getCurrentSession();
  Object result;
  result = sessionUnit.run(sess);
  sess.flush();
  return result;
 }

 public void setSessionFactory(SessionFactory sessionFactory) {
  this.sessionFactory = sessionFactory;
 }

 @Transactional
 public boolean isObjectPersistent(Object object) {
  return sessionFactory.getCurrentSession().contains(object);
 }
}

当我试着打电话的时候 isObjectPersistent()

我还从完整的堆栈跟踪中注意到正在调用OpenSessionInViewFilter,我不确定这是否相关。如果需要剩余的堆栈跟踪,请告诉我。

这是我的应用程序上下文.xml:

如何让我的DAO开始一个事务,在该方法结束时提交,或者在出错时回滚?我希望使用尽可能最小的/标准的配置;如果有选择的话,我更喜欢注释而不是XML。

编辑:

使用调试器,我确定存储在TransactionInterceptor会话持有者映射中的SessionImpl与调用时在DAO方法中检索到的SessionImpl不是同一个会话sessionFactory.getCurrentSession会话(). 有人能解释这是为什么吗?我做错什么了?魔法不起作用。=(

在启动期间,我还注意到控制台中的以下消息:
