# 基于阿里Fescar分布式事务解决案例

一、什么是Fescar？

Fescar全称为：Fast Easy Commit And Rollback，是阿里巴巴公司基于TXC和GTS于2019年开源的微服务架构分布式事务解决方案。该方案基于java实现、简单易用、性能强悍、业务侵入低，是一款能够解决大多数分布式事务场景的极佳选择。原理解析请关注 : https://github.com/alibaba/fescar

二、原理浅析和场景展示

​ Fescar原理图浅析



三、核心技术栈

* SpringBoot 2.0.8.RELEASE（2.0以后第一个GA版本）
* SpringCloud Finchley.SR2
* SpringCloudOpenFeigin
* Durid 1.1.10（阿里巴巴开源高性能数据源连接池）
* Mybatis 3.4.6（Mybatis-3）
* Dubbo 2.6.5（阿里巴巴开源高性能RPC框架）
* Fescar 0.2.1（阿里巴巴开源分布式事务解决方案，第二个小版本）
* Nacos 0.8.0（阿里巴巴开源注册中心/配置中心）

四、实现以及规划

* 当前版本实现SpringBoot + Dubbo + Mybatis + Nacos + Fescar技术整合，实现如何在微服务架构中使用分布式事务框架Fescar
* 之后版本将完善流程，并使用Nacos作为配置中心（现在Nacos只是作为注册中心）
* 接下来版本等到Fescar完善到0.5.0版本后开始支持SringCloud相关技术栈，将实现在Cloud微服务架构中解决分布式事务
* 计划暂定上述

五、使用该案例说明

1. 前往Fescar Github官方页面下载最新版本的 https://github.com/alibaba/fescar/releases

2. 前往Nacos Github官方页面下载最新版本的 https://github.com/alibaba/nacos/releases

3. clone此项目到本地，使用maven构建导入IDEA编辑器中，配置项目使用的maven仓库和JDK版本（1.8）

4. 将sql目录中的sql脚本导入到mysql数据库中，在此之前先创建数据库 db_gts_fescar，设置用户名密码为root root

5. 模块说明：

- samples-account 用户账户微服务模块
- samples-dubbo-business-call 业务发起方模块
- samples-common 项目公共架构模块
- samples-order 订单微服务模块
- samples-storage 库存微服务模块

6. 首先启动Nacos和Fescar，中间件具体使用说明详见上述Github官方页

7. 分别启动samples-account、samples-order、samples-storage、samples-dubbo-business-call四个模块，确定微服务都注册到Nacos和Fescar

8. 使用Postman工具请求Post接口地址：http://localhost:8104/business/dubbo/buy 模拟发起下单业务请求，成功后返回200

9. 接下来测试全局回滚功能，打开samples-dubbo-business-call模块下的 BusinessServiceImpl类，打开被注释的代码

```
if (!flag) {
throw new RuntimeException("测试抛异常后，分布式事务回滚！");
}
```

10. 再次请求测试发生异常后全局事务被回滚
