微服务集成seata分布式事务 at模式快速验证

本次demo代码地址

https://gitee.com/xionggd/my-cloud

业务场景：

多个数据库、多个微服务
多个微服务、单个数据库
... 这些都会涉及到分布式事务的处理

微服务集成 Seata 的 AT 模式（Auto Transaction Mode）主要用于分布式系统中需要跨多个服务/数据库保证事务一致性的场景。AT 模式是一种对业务代码无侵入的分布式事务解决方案，适合快速接入和验证。

一般用于以下场景：

• 订单、支付、库存等业务模块分离的电商系统

  • 示例：下单时需同时操作订单服务、库存服务、用户账户服务，要求这些操作要么全部成功，要么全部失败。

• 金融类系统中的多账户转账

  • 示例：从一个账户扣款，同时向另一个账户加款，两个操作分布在不同的微服务中。

• 物流系统中状态更新与费用计算解耦

  • 示例：物流状态变更触发计费服务，两个服务之间需要事务一致性。

• 涉及多个数据库写操作的业务流程

  • 示例：用户注册后触发用户中心、积分系统、消息通知等多个服务的数据写入。

---

使用 AT 模式的优势（适用于快速验证）：

• ✅ 对业务逻辑无侵入，只需添加注解即可开启全局事务
• ✅ 支持自动回滚和提交
• ✅ 支持主流数据库（如 MySQL、Oracle、PostgreSQL）
• ✅ 配置简单，易于集成

---

快速验证建议步骤：

1. 引入 Seata 客户端依赖（如 seata-spring-boot-starter）
2. 配置 TC（事务协调器）地址（Seata Server）
3. 在入口方法上添加 @GlobalTransactional 注解
4. 在各个微服务中配置数据源代理以支持分支事务
5. 编写测试用例模拟分布式写操作并观察事务一致性

示例代码片段：

@GlobalTransactional
public void placeOrder(Order order) {orderService.create(order);inventoryService.reduceStock(order.getProductId(), order.getCount());accountService.deductBalance(order.getUserId(), order.getTotalPrice());
}

---

注意事项：

• 数据库表需包含 undo_log 表用于事务回滚
• 不适合超大规模并发或高吞吐场景（可考虑 TCC 或 Saga 模式）

Nacos 环境搭建与启动

nacos 下载

https://nacos.io/download/nacos-server/?spm=5238cd80.2ef5001f.0.0.3f613b7c0cg6rw

nacos 配置文件

• 这里使用mysql作为nacos的持久化工具，修改配置文件如下
  • nacos解压的目录： nacos-3.0.1\conf\application.properties

application.properties：

启动nacos

进入目录启动
注意需要jdk17+

• 设置环境变量
  *** 这里“C:\Users\jdks\graalvm-jdk-21.0.7”要替换你jdk17+所在目录
  *** 这里“C:\Users\jdks\graalvm-jdk-21.0.7”要替换你jdk17+所在目录
  *** 这里“C:\Users\jdks\graalvm-jdk-21.0.7”要替换你jdk17+所在目录

set JAVA_HOME=C:\Users\jdks\graalvm-jdk-21.0.7

• 单机启动

startup.cmd -m standalone

• 12345678901234567890123456789012 编译后的 base64：
  启动需要数据这个，控制台输入

启动seata

• 进入bin
  
• 输入cmd
  
• 输入启动命令, seata 也是使用的db数据库持久化

seata-server.bat -p 8091 -h 127.0.0.1 -m db

• 进入seata控制台

用户名：seata
密码：seata

• 登录
  

启动项目测试分布式事务

测试用例如下：

** 订单服务（order-boot） -> 扣除库存(storage-boot) -> 扣除账户金额(account-boot) **

进入git 拉取代码

git clone https://gitee.com/xionggd/my-cloud.git

导入idea

• idea 选择： file -> Open 你clone的代码库
  
  ** 按顺序安装依赖 **
• 1. my-dependencies 安装依赖
     
• 2. my-starter 安装依赖
     

3. my-component-parent 安装依赖
   

4. my-boot-api 安装依赖
   

5. my-boot-parent 编译项目
   

导入所需数据库（建立3个数据库）

• 这里模拟多个数据库，我本地 创建3个数据：分别是 用户库、订单库、仓储依次执行sql
• my_account.sql 账户用户库

启动项目

• 启动 account-boot 服务（用户账户）
  

• 启动 order-boot 服务 （订单）
  

• 启动 storage-boot 服务 （仓储）
  

启动后查看nacos

• 服务启动情况
  

• nacos注册中心查看服务
  

测试seata

• 数据库目前情况：

  • account表数据
    

  • order表数据
    

  • storage表数据
    

情况1：（正常情况）数据库ACID 一致

• 请求采购单接口：

  • 订单服务api 接口
    

  get 请求zhangsan 采购 1002 数量 1：
  http://localhost:9223/order/purchase?userId=zhangsan&commodityCode=1002&orderCount=1
  

• 浏览器请求结果：
  

• 数据库情况：
  用户表 money - 1
  
  order订单表创建了一个订单
  
  仓库被采购了 1002 一件数量
  

情况2：（异常情况）：模拟异常，停掉account服务-数据库ACID 一致

• 请求

  get 请求zhangsan 采购 1002 数量 1：
  http://localhost:9223/order/purchase?userId=zhangsan&commodityCode=1002&orderCount=1
  

• 浏览器请求结果：
  
  
• 数据库
  

结果：全局事务生效

情况3：（异常情况）: 模拟account 报错,调整代码，3个服务正常运行

• 调整 account-boot 服务代码
  

• 启动account 服务
  
  

• 请求

  get 请求zhangsan 采购 1002 数量 1：
  http://localhost:9223/order/purchase?userId=zhangsan&commodityCode=1002&orderCount=1
  

• 浏览器请求结果：
  

• idea 日志
  

• 数据库情况
  

• 结果：全局事务生效

seata AT模式全局事务测试结束
