Seata 参数配置

2.表结构

3.pom

1.依赖seata-spring-boot-starter，支持yml、properties配置(.conf可删除)，内部已依赖seata-all
2.依赖spring-cloud-alibaba-seata，内部集成了seata，并实现了xid传递

4.yml（可以直接放在nacos对应的配置信息里面）

seata:
  tx-service-group: yg_tx_group #与config.txt 中的service.vgroupMapping.yg_tx_group=default一致
  service:
    vgroup-mapping:
      yg_tx_group: default #与config.txt 中的service.vgroupMapping.yg_tx_group=default一致
    grouplist:
      default: ip:8091 #seata 服务地址

5.seata-server服务注册参数配置

registry {
  # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
  type = "nacos"

  nacos {
    application = "seata-server"
    serverAddr = "ip:18848"
    group = "dev_seata_group"
    namespace = "dev_namespace"
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
}

config {
  # file、nacos 、apollo、zk、consul、etcd3
  type = "nacos"

  nacos {
    serverAddr = "ip:18848"
    namespace = "dev_namespace"
    group = "dev_seata_group"
    username = "nacos"
    password = "nacos"
    dataId = "seataServer.properties"
  }
}

6.seataServer.properties
