ssh关于object转为entity对象的问题

    @Override
    public User selectUser(User user) {
        
        Session se = sf.getCurrentSession();
        String hql = "select * from user where email=? and pwd=?";
        User uu =  (User) se.createSQLQuery(hql).addEntity(User.class).setParameter(0, user.getEmail()).setParameter(1, user.getPwd()).uniqueResult();
        
        
        return uu;
    }
