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
客户端搭建
pom依赖
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

seata-client-demo.yml 配置文件
在 nacos 创建 seata-client-demo.yml 配置文件 用于编写客户端 seata 配置
# seata配置

数据库配置
在客户端连接的业务数据库 增加 undo_log 表
-- for AT mode you must to init this sql for you business database. the seata server not need it.
