addFlashAttribute重定向页面传值获取不到

Question

if ((userControllerPojo.getVerificationCode1().trim()).equals(session.getAttribute("strCode"))){
if ((userService.findbyphone(user.getPhone()))!=null){
model.addAttribute("regpdited","此手机号已经注册，请前往登录");
}else {

        int i = userService.InsertUserbyPhone(user);
        if (i == 1) {
            String state = "注册成功，请前往登录";
            model.addAttribute("state",state );
        } else {
            model.addAttribute("state", "注册失败，请重新注册");
            return "/Regedit";
        }
    }
}else {
    Object Vcode  = "Login Success";
    ar.addFlashAttribute("Vcode",Vcode);

    return "redirect:/Regedit.jsp";
}
return "/SkipShow";

}
调试点在 ar.addFlashAttribute("Vcode",Vcode);

没有值，watch as object能找到flashattributes的值是Vcode的值，但是为什么html用el表达式￥{Vcode}获取不到

Answer 1

${Vcode},你这里应该用${requestScope.Vcode}
