:confused: 或许你在网上看过一些资料,了解一些分布式事务的解决办法,然而,一切还只是停留在理论阶段。

:confused: 或许你知道可以通过可靠消息、TCC、最大努力通知等方案来解决分布式事务问题,然而,一切还只是停留在理论阶段。

:confused: 或许你能说出来可以通过一些开源的技术来实现分布式事务,然而,一切还只是停留在理论阶段。

:pensive:    然而,网上都是理论性的文字介绍,文章到处转发、复制,没有项目案例以及代码可供参考学习。即使存在,也是收费!

【总结】常用的分布式事务解决方案

  • 刚性事务

全局事务(标准的分布式事务)

  • 柔性事务

可靠消息最终一致(异步确何型)

TCC (两阶段型、补偿型)

最大努力通知(非可靠消息、定期校对)

> 项目业务功能说明

以【商城下单支付】为核心功能,业务流转过程中会涉及到各系统之间的服务调用,比如:支付通知、商户通知、订单服务、积分服务、会计服务等。

每个服务之间都是独立的进程,具有可独立部署、业务解耦、扩展性强的特点。

最终,你将会知道如何解决分布式事务的问题。。

> 项目技术选型

- 项目主要采用Dubbo作为服务治理框架

- 采用SpringBoot作为微服务开发框架。服务之间可独立部署、业务解耦、扩展性好。

- 项目整体框架为Spring、SpringMVC、Mybtais、Mysql、Zookeeper、ActiveMQ、Dubbo、JSP、Dwz(富客户端)等。

> 项目功能模块划分

通过模拟真实业务场景,最终通过代码来实现和解决分布式事务,故需要对业务进行拆分,不同的服务拥有属于自己的DB库。
项目功能模块以及系统服务架构划分如下:

01. 在线商城系统

02. 支付网关系统

03. 银行支付通知(模拟通知回调)

04. 订单服务

05. 积分服务

06. 会计原始凭证记账服务

07. 账户服务

08. 商户通知服务

09. 可靠消息服务

10. TCC服务

11. 消息状态确认子系统

12. 消息恢复子系统

13. 消息管理子系统

14. BOSS系统

15. (后续更新)

> 第三方jar说明

1、将项目拉取到本地之后,可能会出现tcc-transaction相关的jar文件找不到的情况,如下图所示:

tcc-transaction框架

  原因是因为tcc-transaction框架是github上开源的框架,并非maven中央仓库。

  tcc-transaction框架地址:https://github.com/changmingxie/tcc-transaction

  我已经打包好了,可以到https://gitee.com/zhoubang85/zb-pay-dubbo/attach_files中下载,导入到本地maven仓库即可。

> 项目打包与部署(陆续更新)

  为了更加贴近实际企业项目的部署,特写了一份Jenkins项目自动化构建部署的教程,方便大家学习。
