SEATA-1.6.1

一、简介

  • 本文主要介绍分布式事务框架seata（seata版本1.6.1）的window版本安装以及springboot与seata的整合的事务回滚案例；
  • seata的官方文档路径： http://seata.io/zh-cn/
  • 本文介绍的方式是AT模式，采用的中间件是nacos，存储类型为db模式；
  • 本文默认你已会nacos的安装，如果不会请移步nacos的官方文档进行搭建；
  • 之前部署过 1.4.0 版本的，相对于1.4.0版本，1.6.1版本在注册nacos时仅使用了1个配置文件即可[1.4.0会自动生成一大堆的配置文件]，并且1.6.1提供了访问控制台可以用来查询xid的记录。

二、Seata单节点部署

2.1 下载seata-server服务端

2.2 配置数据库

      boss-thread-size: 1

2.5 启动seata服务

  • 在seata的bin目录，直接运行 seata-server.bat 即可，即可看到如下日志；

  • 此时，在nacos发现seata服务已经注册，如下

  • 此时，在浏览器输入seata的地址： http://localhost:7091 即可登录seata控制台查看事务信息和全局锁信息，如下

三、SEATA高可用部署

3.1 复制上面的单机版seate目录为三个，分配修改不同端口

3.2 分别在三个文件的bin目录调用seata-server.bat来启动即可，之后会在nacos看到集群节点

3.3 控制台地址可以切换不同端口7091，7092，7093均进行访问；
