  - 快速验证建议步骤：
  - 注意事项：
- 工具环境
- 微服务版本选择
- Nacos 环境搭建与启动
- - nacos 下载
  - nacos 配置文件
  - nacos 数据库文件
  - 启动nacos
- Seata 环境搭建与启动
- - seata 下载
  - seata 配置文件
  - 添加数据库驱动
  - seata数据库文件
  - 启动seata
- 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
  - 导入idea
  - 导入所需数据库（建立3个数据库）
  - 启动项目
  - 测试seata
  - 情况1：（正常情况）数据库ACID 一致
  - 情况2：（异常情况）：模拟异常，停掉account服务-数据库ACID 一致
  - 情况3：（异常情况）: 模拟account 报错,调整代码，3个服务正常运行

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：

引入 Seata 客户端依赖（如 seata-spring-boot-starter）
配置 TC（事务协调器）地址（Seata Server）
在入口方法上添加 @GlobalTransactional 注解
在各个微服务中配置数据源代理以支持分支事务
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 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：

# 位于25 - 33 行 启用mysql配置
#*************** Datasource Related Configurations ***************#
### nacos.plugin.datasource.log.enabled=true

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

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)

在这里插入图片描述

进入git 拉取代码

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

在这里插入图片描述

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
1. my-starter 安装依赖

my-component-parent 安装依赖
my-boot-api 安装依赖
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

-- 如果存在就删除，这里不要删，自行处理
-- DROP DATABASE IF EXISTS `my_account`;-- 创建数据库

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

在这里插入图片描述

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
