【Thymeleaf】让页面上显示session中的值

控制器中设值部分：

    @PostMapping(value="/userLogin")
    public ModelAndView login(String uname,String pswd,HttpSession httpSession) {
        User user=userService.searchUserByNamePswd(uname, pswd);
        
        if(user!=null) {
            httpSession.setAttribute("user", user);
            logger.info("Now User:{} logged in.",user.getName());
            return new ModelAndView("blank");
        }else {
            ModelAndView mav=new ModelAndView("login");
            mav.addObject("errMsg", "用户名或密码有误.");
            return mav;
        }
    }

页面上取值部分：

<span th:text="${session.user.name}">user name</span>
