String hql = "from User where username=? and password=?";
Query query = session.createQuery(hql);
query.setString(0, username);
query.setString(1, password);
return (User) query.uniqueResult();
username和password都是正确的 为什么返回为null呢？
String hql = "from TbUser where id=?";
Query query = session.createQuery(hql);
query.setString(0, id);
return (User) query.uniqueResult();
id可以返回值
Hibernate中Query.uniqueResult()
