调用代码User与Message是一对多的关系
public Users queryUsers(final int id){
return (Users)getHibernateTemplate().execute(new HibernateCallback() {

public Object doInHibernate(Session session)
throws HibernateException, SQLException {

String hql = "from Users where id=:id ";
Query query = session.createQuery(hql);
query.setInteger("id",id);
List <Users> list = query.list();
return list.get(0);
}
});
}
public class UserAction extends Action {

private TestDao testDao;

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {

Users user = testDao.queryUsers(1);
System.out.println(user.getMessages().size());
return mapping.findForward("ok");
}
}

执行代码抱错...Session is closed...
求高手帮忙解决呀，困扰我很多天了
