1 添加自定义Key类

public class GoodsKey extends BasePrefix {
    private GoodsKey(int expireSecondes, String prefix) {
        super(expireSecondes, prefix);    }

    public static GoodsKey getGoodsList = new GoodsKey(60000, "goodslist");    public static GoodsKey getGoodsDetail = new GoodsKey(60000, "goodsdetail");}

2 修改Controller

//    @RequestMapping("/to_list")    @RequestMapping(value="/to_list", produces="text/html")
    @ResponseBody    public String toLogin(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);//        return "goods_list";        // 取缓存        String html = redisService.get(GoodsKey.getGoodsList, "", String.class);        if(!StringUtils.isEmpty(html)){
            return html;        }
        // 手动渲染        SpringWebContext ctx = new SpringWebContext(request, response, request.getServletContext(),                request.getLocale(), model.asMap(), applicationContext);        html = thymeleafViewResolver.getTemplateEngine().process("goods_list", ctx);        if(!StringUtils.isEmpty(html)){
            redisService.set(GoodsKey.getGoodsList, "", html);        }
        return html;    }

2 对象缓存

# 测试
java -jar miaosha.jar
# 如果遇到tomcat端口已经被占用 了，那就去将占用改端口的pid给kill掉
# 具体方法：
ps -ef | grep miaosha.jar


# 然后重新部署项目，然后测试
 java -jar miaosha.jar  2>&1 
rm -f *.jtl
 ./apache-jmeter-5.4.1/bin/jmeter.sh -n -t  miaosha_to_list_add_redis_5000_10.jmx -l  miaosha_to_list_add_redis_5000_10.jtl
