点击修改之后重定向到查询页面报错
查询的controller
 @RequestMapping("/getuser")
    public String getUserList(@ModelAttribute("yonghulist") VisitorInfo visitor,@ModelAttribute("pageindex")int pageindex ,HttpServletRequest request,Model m)
    {
        int pageSize  = 10;
        int rowCount = dao.getcount();
        int pageIndex = pageindex;        
        PageInfo page=PageUtil.getPageInfo(pageSize, rowCount, pageIndex);
        List<VisitorInfo> yonghulist = dao.getUserList(page);
        m.addAttribute("yonghulist", yonghulist);
        m.addAttribute("page",page);
        return "page";
    }
修改的controller
 @RequestMapping(value={"/user"})
    public String getupdateuser(VisitorInfo info,Model m){
        int result=dao.updateuser(info);
        m.addAttribute("result",result);
        return "redirect:getuser";
    }
