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
