1、下载seata1.2.0的包解压文件，Windows使用bat启动

https://github.com/seata/seata/releases/download/v1.2.0/seata-server-1.2.0.zip

2、修改file.conf/registry.conf文件

一：file文件中的mode: 指的是文件存储的形式，默认是file我们使用db数据库存储，指定数据库连接的地址，还需要创建三张表，sql脚本应该很多地方都有

二：registry文件中的type指的是注册的类型。我们这里使用的是eureka，更多人推荐的应该是nacos

3、在客户端，在pom.xml加入依赖

        <!--seata -->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-seata</artifactId>
        </dependency>

我以为是ok的了，但是启动报错了

Disconnected from the target VM, address: '127.0.0.1:63421', transport: 'socket'

Process finished with exit code 1

原因，seata-spring-boot-starter已经包含的自动注册类，可以丢弃file.conf和registry.conf两个文件。spring-cloud-starter-alibaba-seata使用的seata版本比较旧且它的自动注册类需要使用file.conf和registry.conf，不利于环境的区分和配置

我们这里需要排除spring-cloud-starter-alibaba-seata提供的自动注册类

在启动类加上

@SpringBootApplication(exclude = {GlobalTransactionAutoConfiguration.class})

加上这个启动类的话，我们的客户端根本没有注册到服务器，说明加这个，我们根本就没有用到seata

其实在父类pom中引入版本控制，子类继承就ok。

父类

注册类型为eureka 如果启动seata报错，说默认使用的是file注册的话，可以加上这段

父子pom文件是最重要的，我个人是通过这种方式实现了seata集成
