no available service found in cluster 'xxx', please make sure registry config correct and keep your seata server running 事务分组名没有配置正确，入门可以先看公告教程。 事务分组与高可用：http://seata.io/zh-cn/docs/user/txgroup/transaction-group-and-ha.html 事务分组介绍：http://seata.io/zh-cn/docs/user/txgroup/transaction-group.html，此回答整理自钉群“3群-Seata 开源讨论群”

seata客户端和服务端配置不一致导致的，对照着服务端，在代码中把客户端的配置一一修改之后重启项目问题消失了。

客户端配置

#seata配置
seata:
  enabled: true
  #Seata 应用编号，默认为 ${spring.application.name}
  application-id: ${spring.application.name}
  #Seata 事务组编号，用于 TC 集群名
  tx-service-group: ${spring.application.name}-group
  #关闭自动代理
  enable-auto-data-source-proxy: false
  #服务配置项
  service:
    #虚拟组和分组的映射
    vgroup-mapping:
      paas-protocol-group: default
  config:
    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848
      namespace:
      #可选
      username: nacos
      #可选
      password: nacos
      # 这是默认值
      # data-id: seata.properties
      # 这是默认值
      group: SEATA_GROUP

  registry:
    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848
      namespace:
      #可选
      username: nacos
      #可选
      password: nacos
      #可选
      application: seata-server
      #默认值和 config 的 SEATA_GROUP 不一样 
      group: SEATA_GROUP
      # 可选  默认
      cluster: default 

服务端配置

registry {
  type = "nacos"
  nacos {
    application = "seata-server"
    serverAddr = "127.0.0.1:8848"
    group = "SEATA_GROUP"
    namespace = ""
    cluster = "default"
    username = "nacos"
    password = "nacos"
  }
}

config {
  type = "nacos"
  nacos {
    serverAddr = "127.0.0.1:8848"
    namespace = ""
    group = "SEATA_GROUP"
    username = "nacos"
    password = "nacos"
  }
}
