小弟，高分求问题解决办法，大家多多支招，感激不尽

快来啊  郁闷一星期了
运行流程如下：
String string = employeeDao.isLogin(f.getCode(),f.getPassword());

ActionErrors errors = new ActionErrors();

if(string.equals("登陆成功"))
{
Users userCode =employeeDao.queryById(code).getUsers();
System.out.println(userCode);
request.setAttribute("userCode", userCode);

return indexPage(mapping, form, request, response);                             （下面无关的省去了）                                        |

解决方案 »

  1.   

    在调试过程中Expressions显示"request.getAttr...ute("userCode")"= null
    控制台显示的是：org.hibernate.TypeMismatchException: Provided id of the wrong type. Expected: class java.lang.String, got class com.baidu.manageSystem.machineRoom.dto.Users
      

  2.   

    org.hibernate.TypeMismatchException: Provided id of the wrong type. Expected: class java.lang.String, got class com.baidu.manageSystem.machineRoom.dto.Users
    这不是告诉你了吗？类型不匹配，你好好看看，你这里放入的是什么类型
      Users userCode =employeeDao.queryById(code).getUsers();
                System.out.println(userCode);
                request.setAttribute("userCode", userCode);
    你这里取出来是什么类型
    public ActionForward jurisdiction(ActionMapping mapping, ActionForm form,
                HttpServletRequest request, HttpServletResponse response) throws Exception 
                {
                UserRights room = new UserRights();
                UserRightsForm f = (UserRightsForm) form;
                Users users =new Users(); //(Users) request.getAttribute("userCode");
                users.setCode((String)request.getAttribute("userCode"));

    就是看不出来，才请大哥们的   我才弄java不久
