Seata 官网基于 docker 部署：https://seata.io/zh-cn/docs/ops/deploy-by-docker.html

1. 直接在 虚拟机 上执行 

docker run --name seata-server \
-p 8091:8091 \
-e SEATA_IP=192.168.0.101 \
-e SEATA_PORT=8091 \
seataio/seata-server

 

拉取 lastest 镜像并启动容器

 

其中 192.168.0.101 为虚拟机ip

 

2. 项目 的pom.xml 里导入 坐标（需要注意 相关组件版本：https://github.com/alibaba/spring-cloud-alibaba/wiki/%E7%89%88%E6%9C%AC%E8%AF%B4%E6%98%8E）：

<dependency>
    <groupId>com.alibaba.cloud</groupId>
    <artifactId>spring-cloud-starter-alibaba-seata</artifactId>
    <version>2.2.5.RELEASE</version>
</dependency>

 

3. SpringBootApplication 启动类上添加  @EnableAutoDataSourceProxy 注解

 

 

 

4.  修改 hailtaxi-driver-dev.yml 配置，添加 seata 相关内容：

5. idea 启动项目，报错： endpoint format should like ip:port

可能的原因：估计和加载顺序、spring.application.name 配置被覆盖有关。

 

解决方案：

将 seata 配置移到 bootstrap.yml 配置文件中即可，即 和  spring.application.name 一起加载
