解决方法：
1检查hql
这个错误是在页面中报出的：是hql语言出错了：
from systemuser where username=‘"+username+"’and password=‘"+password+“’”);
应该改成：from SystemUser where username=‘"+username+"’and password=‘"+password+“’”);
2，antlr包的版本问题
注意：hql语言是面向对象的 所有的东西是按照实体类来查询的 不是按照sql思路从第存数据开始看的；
这也是hibernate的成功之处；
题外话：hibernate的鼻祖 原来不会sql语言；在做项目是吃了大亏 然后就突发奇想 自己研究出来hibernate 让那些不会sql语句的人 也能实现sql相同的功能
