  1. LoginForm loginForm = (LoginForm) form;
    User user=loginDao.findLogin(loginForm.getUserName());
    List <Long> list=loginDao.findLoginPriviliege(loginForm.getUserName());
    public User findLogin(String name){
    return (User)getSession()
    .createQuery("from User u where u.UserName=?")
    .setParameter(0,name)
    .uniqueResult();
    }
      

  2. createQuery("from User u where u.UserName='?'")
    试试
