# nacos 控制台 http://localhost:8848/nacos/    默认密码:  nacos - nacos

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
