解決方法：
1檢查hql
這個錯誤是在頁面中報出的：是hql語言出錯了：
from systemuser where username=‘"+username+"’and password=‘"+password+“’”);
應該改成：from SystemUser where username=‘"+username+"’and password=‘"+password+“’”);
2，antlr包的版本問題
注意：hql語言是面向對象的 所有的東西是按照實體類來查詢的 不是按照sql思路從第存數據開始看的；
這也是hibernate的成功之處；
題外話：hibernate的鼻祖 原來不會sql語言；在做項目是吃了大虧 然後就突發奇想 自己研究出來hibernate 讓那些不會sql語句的人 也能實現sql相同的功能
