一、页面缓存优化

1.注入ThymeleafViewResolver和ApplicationContext

@Autowired
ThymeleafViewResolver thymeleafViewResolver;
@Autowired
ApplicationContext applicationContext;

2.取缓存

//取缓存
String html = redisService.get(GoodsKey.getGoodsList, "", String.class);
if (!StringUtils.isEmpty(html)){
    return html;
}

3.无缓存时，手动渲染模板输出结果

SpringWebContext ctx = new SpringWebContext(request,response,
                                            request.getServletContext(),request.getLocale(),model.asMap(),applicationContext);
//手动渲染
html = thymeleafViewResolver.getTemplateEngine().process("goods_list", ctx);
if (!StringUtils.isEmpty(html)){
    redisService.set(GoodsKey.getGoodsList,"",html);
}
return html;

二、页面静态化

1.通过ajax异步请求，js渲染页面

$.ajax({
        url:"/goods/detail/"+goodsId,
        type:"GET",
        success:function(data){
            if(data.code == 0){
                render(data.data);
            }else{
                layer.msg(data.msg);
            }
        },
        error:function(){
            layer.msg("客户端请求有误");
        }
    });

2.修改 controller 层返回 Vo 对象

GoodsDetailVo vo = new GoodsDetailVo();
vo.setGoods(goods);
vo.setUser(user);
vo.setRemainSeconds(remainSeconds);
vo.setMiaoshaStatus(miaoshaStatus);
return Result.success(vo);
