1.registry.conf

以下为配置信息 

 
registry {
 # file 、nacos 、eureka、redis、zk、consul、etcd3、sofa
 type = "nacos"
 nacos {
   application = "seata-server"
   serverAddr = "10.100.1.43:8848"
   group = "SEATA_GROUP"
   namespace = "9678eac7-9884-4eef-9876-8654ee798d7d"
     cluster = "default"
   username = "nacos"
   password = "nacos"
 }
}
config {
 # file、nacos 、apollo、zk、consul、etcd3
 type = "nacos"
 nacos {
   serverAddr = "127.0.0.1:8848"
     namespace = "9678eac7-9884-4eef-9876-8654ee798d7d"
   group = "SEATA_GROUP"
     cluster = "default"
   username = "nacos"
   password = "nacos"
 }
}

2.file.conf

store {
 ## store mode: file、db、redis
 mode = "db"
 
 ## database store property
 db {
   ## the implement of javax.sql.DataSource, such as DruidDataSource(druid)/BasicDataSource(dbcp)/HikariDataSource(hikari) etc.
   datasource = "druid"
   ## mysql/oracle/postgresql/h2/oceanbase etc.
   dbType = "mysql"
   driverClassName = "com.mysql.jdbc.Driver"
   url = "jdbc:mysql://xxxx:3306/seata?allowMultiQueries=true&autoReconnect=true&useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai"
   user = "root"
   password = "xxxxx"
   minConn = 5
   maxConn = 30
   globalTable = "global_table"
   branchTable = "branch_table"
   lockTable = "lock_table"
   queryLimit = 100
   maxWait = 5000
 }

3.应用程序  application.yml配置

#Seata分布式事务配置(AT模式)
seata:
 enabled: true #开启seata支持
 application-id: ${spring.application.name}
 #客户端和服务端在同一个事务组
 tx-service-group: my_test_tx_group #这里需要和config.txt文件中 service.vgroupMapping.my_test_tx_group=default 相一致
 enable-auto-data-source-proxy: true
 config:
   type: nacos
   nacos:
     namespace: "9678eac7-9884-4eef-9876-8654ee798d7d"
     serverAddr: 10.100.1.43:8848
     group: SEATA_GROUP
     username: "nacos"
     password: "nacos"
 service:
   vgroup-mapping:
     my_test_tx_group: default #注意必须与 tx-service-group相同
 #服务注册到nacos
 registry:
   type: nacos
   nacos:
     application: seata-server #这里必须和 registry.conf, nacos中application="seata-server"同名
     server-addr: 10.100.1.43:8848
     group: SEATA_GROUP
     namespace: 9678eac7-9884-4eef-9876-8654ee798d7d #必须添加自己的NameSpace否则默认为 public
     cluster: default
     username: "nacos"
     password: "nacos"
