import org.thymeleaf.context.IWebContext;
import org.thymeleaf.context.WebContext;

当你想把页面信息全部获取出来存到redis缓存中使用时，SpringWebContext在Spring5中报错

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

代码报错1，很早版本之前的解决办法如下（SpringWebContext在spring5中过时）

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

但是最新版本仍然报错

根据WebContext提示

 解决办法如下

        IWebContext ctx =new WebContext((IWebExchange) request.getServletContext(),request.getLocale(),Map.of("user",user,"itemList",itemList));
