SSM中页面跳转时，通过model.addAttribute传递的数据出现在URL中

Question

if(user == null) {
            model.addAttribute("error","帐号或密码错误");
            return "redirect:/login/ulogin";
        }else{
            model.addAttribute("uName",user.getUserName());
            return "redirect:/index/";
        }
        
        
  http://localhost:8080/quella/index/?uName=aaa      在index.jsp获取不到uName的值，它却出现在了URL中
        
      

Answer 1

return new ModelAndView("redirect:/user/list?success=true");

Answer 2

html直接用表达式取不到值吧，
var name = '${uName}';
上面那个不行就试一试下面这个
var name = '[[${uName}]]';
