Question

hibernate hql语句弄不了。报错了。郁闷中

public ActionForward displaymove(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response)
{
int id=Integer.parseInt(request.getParameter("id"));
//System.out.println("进入displaymove方法"+id);
Session session=HibernateSessionFactory.getSession();
String hql="from YisoulMove ysm where ysm.id=?";
Query query=session.createQuery(hql);
//query.setInteger(0,id);
YisoulMove ym=new YisoulMove();
List it=query.list();
ym=(YisoulMove) it.get(0);
HttpSession session1=request.getSession(false);
session1.setAttribute("displaymove",ym);
return mapping.findForward("displaymove");
}

我设置了。断点：

Query query=session.createQuery(hql); 这一句就报错了。

错误提示是：

严重: Servlet.service() for servlet action threw exception

Answer 1

堆栈第一条错误是NoSuchMethodError。 antlr.collections.AST.getLine()
是不是你没有加antlr这个包？

Answer 2

java.lang.NoSuchMethodError: antlr.collections.AST.getLine()I

少方法

Answer 3

是不是hql参数设置错了哦

Answer 4

没找到方法,估计是少了jar文件 ,找找antlr这个吧
