总结

项目框架搭建

1. Spring Boot 环境搭建 DemoController.java MainApplication.java application.properties pom.xml
2. 集成Thymeleaf, Result结果封装 CodeMsg.java Result.java application.properties hello.html pom.xml
3. 集成MyBatis+Druid UserDao.java UserService.java application.properties pom.xml SampleController.java
4. 集成Jedis+Redis安装+通用缓存Key封装 RedisConfig.java RedisPoolFactory.java RedisService.java

BasePrefix.java KeyPrefix.java UserKey.java SampleController.java

登录功能

1. 明文密码两次MD5处理（明文+固定salt->用户输入+随机salt） MD5Util.java
2. JSR303参数检验+全局异常处理器(接口的异常, 还未写页面异常) GlobalException.java GlobalExceptionHandler.java LoginVo.java IsMobile.java IsMobileValidator.java ValidatorUtil.java
3. 分布式Session LoginController.java GoodsController.java UserArgumentResolver.java WebConfig.java MiaoshaUserService.java UUIDUtil.java

秒杀功能

1. 商品列表页 (页面缓存)
2. 商品详情页 (url缓存/前后端分离)
3. 订单详情页 (前后端分离)

页面优化技术

1. 页面缓存+URL缓存+对象缓存

2. 页面静态化, 前后端分离 u_uid_gid user_id, order_id 唯一索引防止重复插入com.onejane.miaosha.service.OrderService#createOrder 解决卖超

3. 静态资源优化 js/css 压缩，减少流量，多个js/css组合，减少连接数，cdn就近访问

4. CDN优化(3, 4 未涉及)

接口优化

1. Redis预减库存减少数据库访问
2. 内存标记减少Redis访问
3. RabbitMQ队列缓冲, 异步下单
4. Nginx水平扩展(本机设置)

安全优化

1. 秒杀接口地址隐藏
2. 接口防刷

压测

商品列表

测试计划-添加线程组-2000线程0秒内循环10次 线程组-配置元件-添加http请求默认值：http localhost 8888 线程组-sampler-http请求：get /goods/to_list 线程组-监听器-聚合报告，图形结果，用表格查看结果，聚合报告中的Throughput表示qps 执行->linux top 查看 mysql排名靠上

用户信息

商品列表-禁用 线程组-sampler-http请求：get /user/info - Parameters 添加 token:57c78d16b6704a9f8f0a357b28b097a6 单个token配置

线程组-配置原件-CSV Data Set Config： 多个token配置 Filename C:\Users\JDD\Desktop\config.txt 内容13000000000,57c78d16b6704a9f8f0a357b28b097a6 Variable Names(comma-delimited) userId,userToken Delimiter(use '\t' for tab) , 修改用户信息中参数为 token ${userToken} 执行查看图形结果的qps

redis压测

redis-benchmark -h 127.0.0.1 -p 6379 -c 100 -n 100000　开启100个并发共10万个请求 redis-benchmark -h 127.0.0.1 -p 6379 -q -d 100 开启100个字节的快速请求 redis-benchmark -h 127.0.0.1 -p 6379 -q -n 100000 -t set,lpush 指定方法请求 redis-benchmark -h 127.0.0.1 -p 6379 -q -n 100000 script load "redis.call('set','foo','bar')" 指定命令请求
