SSH中执行HQL语句的org.hibernate.hql.internal.a?报错

SSH框架中,执行的HQL语句如下:

  List<Week> list =  weekService.query("from 表名 w where w.username='"+username+"' and w.hostname="+hostname+" and w.meetingDate="+meetingDate);

控制台报错如下:

line 1:85: unexpected token: Jun

主要错误信息:

 Exception occurred during processing request: unexpected token: Jun near line 1, column 85 [from regularmeeting w where w.username='lida' and w.name=lida and w.meetingDate=Fri Jun 19 18:33:21 CST 2015]

 这里的HQL语句系统报出来的跟我写的不一样  w.name是系统的  我的是w.hostname 而且关键是我不管怎么改HQL语句 都会出现这错误提示 不知道是哪出现问题了.

  再看调用的接口及实现类所执行方法里也没看见写SQL语句的地方,hibernate对应的类映射文件,我这好像也没有,弱弱的问句,还有其他方法可以配置hibernate与实体类或者说表的映射关系么.

   弄了一天都没解决,,急啊 求大神帮帮忙 ,  才学习SSH不久!!!!!!!!!     谢谢!!!!!
