报错原因：
是由于问题所在与解析问题，返回给
@RequestMapping(value = "/to_list" ,produces = "text/html")
public String list(Model model, MiaoshaUser user, HttpServletRequest request, HttpServletResponse response) {
model.addAttribute("user", user);
//查询商品列表
List<GoodsVo> goodsList = goodsService.listGoodsVo();
model.addAttribute("goodsList", goodsList);
String html = redisService.get(GoodsKey.getGoodsList, "", String.class);
if (!StringUtils.isEmpty(html)){
return html;
}
WebContext ctx = new WebContext(request,response,request.getServletContext(),
request.getLocale(),model.asMap());
html =thymeleafViewResolver.getTemplateEngine().process("goods_list",ctx);
return html;
}
返回浏览器是这个html，那么就需要以html形式返回，所以需要加上@responsebody来
