SpringWebContext在Spring5中报错

想把页面信息全部获取出来存到redis缓存中，用

       SpringWebContext ctx = new SpringWebContext(request, response,
                request.getServletContext(), request.getLocale(), model.asMap(), applicationContext);

代码报错，

解决办法（SpringWebContext在spring5中过时）：

  //手动渲染
        IWebContext ctx =new WebContext(request,response,
                request.getServletContext(),request.getLocale(),model.asMap());
