启动 seata 服务端
访问 7091 端口 进入seata 控制台
查看 nacos 服务注册列表
由于 SpringCloud Alibaba seata 使用的客户端为 1.4.2
故排除依赖 手动引入 1.5.X
客户端 application.yml 配置 nacos 连接com.alibaba.cloud spring-cloud-starter-alibaba-seata 2021.0.1.0 io.seata seata-spring-boot-starter io.seata seata-spring-boot-starter 1.5.1

在客户端连接的业务数据库 增加 undo_log 表

最初调用方为 事务发起者 需标记 seata 注解
