介绍

我以前公司开发过的一个红包雨系统,原先公司的红包雨系统只有十万用户,参与红包雨活动的定时红包雨抢红包用户也只有2万多,压测时QPS在三千多的样子,也算是一个高并发项目了,但是还不是特别高,所以希望自己弄一个专门做百万级的QPS压测项目,前期根据自己开发过的那个红包雨高并发项目进行调整,移除掉公司的业务逻辑,仅保留通用抢红包流程,作为Demo项目。后期的开发计划,先完成百万级的QPS红包雨项目,然后在做秒杀、春节抢票等有高并发的业务项目。

高并发百万级QPS红包雨实战demo

使用技术

项目使用技术服务器参数优化

Spring Boot项目配置优化(配置HTTP协议下的数据压缩、配置静态资源缓存、Tomcat线程池配置)

启动时间优化(延迟初始化Bean、spring-context-indexer功能、11项优化启动方案) 同一IP地址请求限流

网关请求校验防篡改

防止请求重复提交

同一用户请求限流

应用服务限流

池化技术(Redis连接池、MySQL连接池、对象池、线程池【自适应核心线程数、自定义拒绝策略、滑动时间窗口、性能监控、重试纪元】)

弹性伸缩、负载均衡(阿里云CLB、Nginx)

定时任务

rediscluster(高可用6个节点)

mysqlcluster(三主六从半同步复制)

rocketmqcluster(dledger高可用9个节点)

分布式锁

防止消息重复消费

多消费组多消费者消费

高并发请求合并

redis批处理

mysql批处理

设计模式(模板方法模式、代理模式、 享元模式)

不可逆加密存储

用户请求鉴权(JWT)

软件架构

red-package-rain-api服务抢红包

red-package-rain-server服务消费红包

spring-cloud-gateway服务网关过滤请求限流用户

spring-cloud-security-oauth2服务鉴权

user服务处理用户请求

安装教程

  1. JDK8环境
  2. 需要准备好Redis、MySQL、RocketMQ
  3. 部署需要准备好centos7环境、Docker、Docker-Compose

使用说明

  1. 先启动spring-cloud-security-oauth2服务
  2. 然后再启动spring-cloud-gateway服务
  3. 剩下的服务启动顺序随意

操作步骤

1.用户服务

批量创建用户任务(每秒一万用户,写入DB并保存用户名和密码到脚本中):

http://localhost:8037/userinfo/startCreateUserTask

关闭创建用户的任务:

http://localhost:8037/userinfo/stopCreateUserTask

写入脚本文件(将用户id、登录的token、时间戳、验签写入脚本):

http://localhost:8037/userinfo/writeScriptFile

2.红包服务

添加红包活动(后台管理系统配置红包活动):

http://localhost:8057/redPackageRainApi/addRedPackageActivity

走网关:

http://localhost:8087/redPackageRainApi/addRedPackageActivity

抢红包:

http://localhost:8057/redPackageRainApi/snatchRedPackage

走网关:

http://localhost:8087/redPackageRainApi/snatchRedPackage

合并请求抢红包:

http://localhost:8057/redPackageRainApi/snatchRedPackageMergeRequest

走网关:

http://localhost:8087/redPackageRainApi/snatchRedPackageMergeRequest

想说的话

目前这个项目还在不断调试中,视频也是录制一段之后,继续调整代码,项目中还有很多技术点没实现的,也不用着急,后续会慢慢添加上去的。

另外大家对这个项目感觉还不错的话,可以留下一个Star让更多人看到这个项目进行学习。
