微服务整合Seata异常处理：no available service ‘default‘ found, please make sure registry config correct

一：YML配置信息

seata:
  enabled: true
  application-id: ${spring.application.name}
  # 事务组
  tx-service-group: my_test_tx_group
  # 数据源代理模式
  enable-auto-data-source-proxy: true
  # 数据源代理模式
  data-source-proxy-mode: AT
  # 事务组
  service:
    vgroup-mapping:
      my_test_tx_group: default
  #整合nacos配置
  config:
    type: nacos
    nacos:
      server-addr: 192.101:8848
      group: SEATA_GROUP
      namespace: d4874eb0-1917-45fd-8dc1-34f6f3f5265a
      data-id: seataServer.properties
      #可选
      username: nacos
      #可选
      password: nacos
  #整合nacos注册中心
  registry:
    type: nacos
    nacos:
      server-addr: 192.101:8848  
      application: seata-server  
      group: SEATA_GROUP 
      username: nacos
      password: nacos
      namespace: d4874eb0-1917-45fd-8dc1-34f6f3f5265a

二：启动异常日志

2022-12-26 22:26:27.065 ERROR 25384 --- [eoutChecker_1_1] i.s.c.r.netty.NettyClientChannelManager  : no available service 'default' found, please make sure registry config correct

三：异常信息排查

3.1：锁定包路径 io.seata.core.rpc.netty

3.2：全局搜索异常关键字：please make sure registry config correct

3.3：问题定位

打断点一层层查看变量信息，最后是获取不到Nacos对应的vgroupMapping键值对信息。

3.3.1 ：注意：如果Seata配置信息是Nacos类型，即使在file文件中配置了vgroupMapping，不是file类型也获取不到，这里用的Nacos，应该在Nacos配置中进行配置

这里的YML中的事务组和Nacos – vgroupMapping配置的事务组信息必须一致

 # 这段不是完整配置信息，单独提出来的
 tx-service-group: my_test_tx_group
   service:
    vgroup-mapping:
      my_test_tx_group: default

seata:
  enabled: true
  application-id: ${spring.application.name}
  # 事务组
  tx-service-group: my_test_tx_group
  # 数据源代理模式
  enable-auto-data-source-proxy: true
  # 数据源代理模式
  data-source-proxy-mode: AT
  # 事务组
  service:
    vgroup-mapping:
      my_test_tx_group: default

service {
   
  #transaction service group mapping
  vgroupMapping.my_test_tx_group = "default"
  default.grouplist = "192..101:8091"
  #degrade, current not support
  enableDegrade = false
  #disable seata
  disableGlobalTransaction = false
}
#client tr

四：问题解决

4.1. 配置 nacos-config.sh 和 config.txt

4.1.1. 编辑nacos-config.sh nacos配置文件加载sh执行文件
