controller：

    @RequestMapping(value = "/regmodel", method = RequestMethod.POST)
   public ModelAndView regmodel(@ModelAttribute("registeruser") RegisterUser registeruser,
           BindingResult result)
   {
       Map<String, String> map = new HashMap<String, String>();
       map.put("registeremail", registeruser.getRegisteremail());
       map.put("registernickname", registeruser.getRegisternickname());
       return new ModelAndView(new RedirectView("renderregister"),map);
   }

jsp：

    <%
       String sEmail = request.getParameter("registeremail");
       String sNickname = request.getParameter("registernickname");
       String ss = request.getParameter("registernickname");
       if(ss!=null){
       byte[] bs =ss.getBytes("ISO-8859-1");
       for(int i = 0; i < bs.length; i++){
          byte b = bs[i];
          if(b==63){
           break;
          }else if(b>0){
           continue;
          }else if(b<0){
           ss = new String(bs,"UTF-8");
           break;
          }
       }
       }
   %>
