goodskill's Introduction

前言

项目命名为 goodsKill 一方面有商品秒杀的意思(好像有点chinglish的味道)，另外也可理解为 good skill，本项目就是希望搭建一套完整的项目框架，把一些好的技术和开发技巧整合进来（偏向于后端技术），方便学习和查阅。

本项目为模拟秒杀项目，提供统一秒杀模拟请求接口，技术上整体采用SpringMVC + Mybatis持久层框架，采用Dubbo3.x^[1]，服务注册发现以及配置中心使用Nacos，支持数据库分库分表、分布式事务，使用状态机完成数据状态间的转换（基于Spring Statemachine实现）。

💎 分支介绍

master分支基于最新Spring Cloud 2023.x + Spring Boot 3.x + JDK21体系构建，目前仅保留核心的模拟秒杀API接口，如需使用Spring Boot 2.7.x + JDK11版本可以切换到tag v2.7.4（支持登录注册以及简单的后台管理功能）。master分支目前升级改造中，功能不够稳定，如遇代码报错建议使用老版本。

本项目功能目前比较简陋且有很多不完善的地方，真实的秒杀场景远比本项目中的实现方式复杂，本项目省略了真实场景中的部分技术实现细节，目前仅作学习参考之用，如果觉得本项目对你有帮助的请多多star支持一下👍_~~。

🔥🔥 秒杀方案

目前实现了几种秒杀方案，通过SeckillMockController提供测试接口

聚合网关Openapi文档地址: http://localhost/doc.html#/home（需要开启网关服务）

Spring Boot Admin应用监控地址: http://www.goodskill.com:19031, 登录用户名密码：user/123456

场景一：Sychronized同步锁实现
场景二：Redisson分布式锁实现
场景三：ActiveMQ实现(已废弃)
场景四：Kafka消息队列实现
场景五：数据库原子性更新
场景六：实时等待秒杀处理结果(已废弃)
场景七：ZooKeeper分布式锁
场景八：使用Redis进行秒杀商品减库存操作，秒杀结束后异步发送MQ，使用MongoDB完成数据落地
场景九：Spring Cloud Stream实现
场景十：Sentinel限流+数据库原子性更新（需搭配sentinel控制台配置资源名limit的流控规则）

可在web控台查看秒杀结果，打印信息类似：

🎯 快速开始

项目根目录goodsKill中执行

  mvn clean install
  或
  #跳过单元测试
  mvn clean install -DskipTests

默认端口启动nacos、redis、mysql、rabbitmq、kafka、zookeeper、elasticsearch，或者使用docker-compose^[2]命令：
```
  docker-compose -f goodskill-simple.yml up -d
```
进入goodskill-web/src/main/sql目录，找到seckill.sql文件，在本地mysql数据库中建立seckill仓库并执行完成数据初始化操作

⚠️️
docker-compose启动MySQL镜像时会自动执行初始化脚本，如已执行过上一步本步骤可跳过

配置host

 127.0.0.1       kafka
 127.0.0.1       nacos
 127.0.0.1       redis
 127.0.0.1       mysql
 127.0.0.1       zookeeper
 127.0.0.1       mongo
 127.0.0.1       elasticsearch
 127.0.0.1       rabbitmq
 127.0.0.1       logstash
 ##如果网关服务部署在远程机器，此处改为相应的远程机器ip
 127.0.0.1       www.goodskill.com

main方法运行OrderApplication类(订单服务)
main方法运行SeckillApplication类(秒杀管理服务提供者)
main方法运行SampleWebApplication类(模拟秒杀web服务)

发送一个秒杀模拟请求：秒杀活动id 1000，商品数量10，执行20次购买操作，使用sychronized同步锁执行，例如：

可直接使用以下命令发送模拟秒杀请求，每个秒杀活动seckillId对应唯一的一个商品id，每次执行接口时会有一个库存初始化动作，接口执行完成后可重复调用

Example 1. 使用sychronized同步锁执行

curl -X POST "http://www.goodskill.com:8080/sychronized" \
-H "accept: */*" -H "Content-Type: application/json" -d \
"{ \"requestCount\": 20, \"seckillCount\": 10, \"seckillId\": 1000}"

Example 2. 使用Redisson分布式锁执行

curl -X POST "http://www.goodskill.com:8080/redisson" \
-H "accept: */*" -H "Content-Type: application/json" -d \
"{ \"requestCount\": 20, \"seckillCount\": 10, \"seckillId\": 1000}"

Example 3. 使用Redisson分布式锁执行，支持动态配置后台线程池核心线程数以及最大线程数

curl --location --request POST 'http://www.goodskill.com:8080/limit' \
--header 'User-Agent: apifox/1.0.0 (https://www.apifox.cn)' \
--header 'Content-Type: application/json' \
--data-raw '{
    "maxPoolSize": 10,
    "seckillId": 1000,
    "corePoolSize": 2,
    "seckillCount": 100,
    "requestCount": 120
}'

请求默认异步执行，可在控制台查看执行日志，如果最终成功交易笔数等于商品数量10则表示没有出现超卖或者少卖问题

🕹️️ 启动其他可选项目步骤

在快速开始部分基础上增加以下步骤即可启动一个完整项目

进入goodskill-gateway模块，通过GatewayApplication类main方法启动服务网关，统一通过网关访问各个服务
- http://www.goodskill.com/api/order/** 对应访问goodskill-order服务
- http://www.goodskill.com/api/seata/** 对应访问goodskill-seata服务
- http://www.goodskill.com/api/seckill/** 对应访问goodskill-seckill服务
- http://www.goodskill.com/api/auth/** 对应访问goodskill-auth服务
- http://www.goodskill.com/api/web/** 对应访问goodskill-web服务
已集成Sentinel限流组件，支持nacos配置中心方式推送限流规则，使用时需启动Sentinel控制台，并以18088端口启动，docker环境暂不支持。
Seata分布式事务测试方法见 Seata分布式事务测试示例运行说明
main方法运行GoodskillAdminApplication类(微服务健康状态指标监控)

❓常见问题

docker es镜像启动失败

出现此问题一般为linux环境，运行以下命令即可 sysctl -w vm.max_map_count=262144 ，或者修改/etc/sysctl.conf文件，追加以下配置：
```
grep vm.max_map_count /etc/sysctl.conf
vm.max_map_count=262144
```
如何使用本项目自定义的OAuth2.0授权服务器进行登录授权？

待完善。。
项目集成的各个框架之间目前的兼容性如何？

本项目目前依赖的各个主流框架的版本比较新，尚未经过完整测试^[3]。
服务启动控制台报ERROR日志 no available service found in cluster 'default', please make sure registry config correct and keep your seata server running 如何解决？

启动seata-server服务即可（docker-compose.yml文件中已提供），可参照Seata官网添加nacos相关配置。如未使用分布式事务，可忽略该错误，不影响服务正常运行
docker-compose无法拉取镜像

hub.docker被墙，国内可使用阿里云镜像加速器，具体操作见阿里云镜像加速器

使用JDK17以上启动项目失败

启动时添加以下jvm参数，例如：

--add-opens java.base/java.lang=ALL-UNNAMED
--add-opens java.base/java.util=ALL-UNNAMED
--add-opens java.base/java.util.concurrent=ALL-UNNAMED
--add-opens java.base/java.math=ALL-UNNAMED
--add-opens java.base/sun.reflect.generics.reflectiveObjects=ALL-UNNAMED

🖲️ 状态机说明

目前秒杀活动状态的控制基于Spring Statemachine状态机实现，使用状态机的优点：

统一控制活动状态，便于状态的集中维护；
防止业务状态被随意更改，保证状态的可控更新；

状态机流程图

📚分库分表情况说明

表	数据库	是否分库	分库字段	是否分表	分表字段
success_killed	MySQL	是（同一服务器中，分为seckill和seckill_01两个库）	seckill_id	是（分为success_killed_0,success_kill_1两张表）	user_phone

📢	其他表均未分库分表，默认使用seckill作为主库

1. 由于SpringCloudAlibaba官方暂未支持Dubbo 3.x，本项目采用dubbo-spring-boot-starter集成

2. 需要安装docker-desktop https://www.docker.com/products/docker-desktop/

3. 附 SpringCloudAlibaba兼容版本说明

goodskill's Issues

goodskill-seata里的依赖有一个拿不到

org.graalvm.buildtools
native-maven-plugin
build下的依赖找不到,需要加个版本号

网关使用kt问题

open idea部署，网关用的是kt，网关启动好没报错。但是网关页面访问直接404

快速开始启动SampleWebJspApplication失败

拉的master分支代码，启动web服务报错同时gooskill服务也报错，Caused by: java.lang.NoSuchMethodError: 'org.apache.dubbo.rpc.RpcContext org.apache.dubbo.rpc.RpcContext.getServerContext()'，看错误信息应该是seata里没有这个方法

秒杀场景八，Redis获取商品及扣库存不是原子操作

在秒杀场景八中，通过redis获取秒杀商品和库存扣除操作不是原子操作，在高并发下是否存在问题？
以及MQ失败（发送失败，或者处理失败，网络抖动），如何处理？

SpringBoot分支GoodsKillRpcServiceApplication启动报错

错误信息如下：

No SecurityManager accessible to the calling code？找不到SecurityUtils这个类，是Shiro过滤器的启动顺序问题吗？

博主您好，我看到您提到由于Shiro兼容性问题以及个人精力有限已移除前端JSP页面、登录注册以及后台管理功能。我在启动Web服务访问login登录页面时出现错误：No SecurityManager accessible to the calling code, either bound to the org.apache.shiro.util.ThreadContext or as a vm static singleton.查阅相关资料后还是未能解决，请问这个是您所提到的兼容性问题吗？还是说我在某些地方没有配置好环境所导致的错误，百思不得其解。如果您有时间的话，能否给予我一个回复，万分感激不尽。
最后想咨询一下博主，可否为该项目建一个交流讨论群呢? 我认为这个项目非常具有学习价值，一定会有很多小伙伴加入！

### Welcome!

Welcome!

Yes, I've searched similar issues on GitHub and didn't find any.
Yes, I've searched similar issues on the Traefik community forum and didn't find any.

What did you expect to see?

Hi,
First of all - I really appreciate the work you've all done on Traefik - I think it's a great project. I've started using it not a long time ago and I love it.

I have a problem with access log - I cannot find any solution, to log real IP when the requests are proxied through CloudFlare. In access logs I can only see the CloudFlare loadbalancers IPs.

I know there are middlewares which rewrite CloudFlare headers for services, but I couldn't find a plugin which would put the real IP in access log.

I know that I can also use JSON format for access log and include headers, like X-Forwarded-For, but I really want to stick with the common format and see the real IPs there.

I've tried configuring ProxyProtocol, but it doesn't seem to help.

I don't have much experience with Go, and Traefik is a pretty big project, but from what I can tell, in pkg/middlewares/accesslog/logger.go on line 227, req.RemoteAddr is used:

...
core[ClientAddr] = req.RemoteAddr
...

I imagine that this is the part, where the source IP for a request is determined for access log.

Can you point me to a valid solution or determine whether that's a feature that could be implemented directly in Traefik?
