Seata+naocs 使用

1. 环境seata1.5.2.   nacos2.1.0

本地配置好nacos之后

新建一个seata的命名空间，seata 需要使用

seata准备

1: 创建mysql的seata数据库  执行\seata-server-1.5.2\script\server\db\mysql.sql

2: 拷贝config.txt   从seata-server-1.5.2\script\config-center\config.txt   移动到seata-server-1.5.2\config.txt 

修改2处地方 存储模式/ 数据库地址 https://www.exyb.cn/news/show-780131.html?action=onClick

store.mode=db

store.db.url=jdbc:mysql://127.0.0.1:3306/demo-seata?useUnicode=true&rewriteBatchedStatements=true
store.db.user=root
store.db.password=123456

3.修改seata-server-1.5.2\conf\application.yml文件 

server:
  port: 7091

spring:
  application:
    name: seata-server

logging:
  config: classpath:logback-spring.xml
  file:
    path: ${user.home}/logs/seata
  extend:
    logstash-appender:
      destination: 127.0.0.1:4560
    kafka-appender:
      bootstrap-servers: 127.0.0.1:9092
      topic: logback_to_logstash

console:
  user:
    username: seata
    password: seata

seata:
  config:
    # support: nacos, consul, apollo, zk, etcd3
    type: nacos
    nacos:
        server-addr: 127.0.0.1:8848
        namespace: 4f4d5421-73ba-4a34-90b6-82b899ea2377
        group: SEATA_GROUP
        username: nacos
        password: nacos
        data-id: seataServer.properties
  registry:
    # support: nacos, eureka, redis, zk, consul, etcd3, sofa
    type: nacos
    nacos:
        application: seata-server
        server-addr: 127.0.0.1:8848
        namespace: 4f4d5421-73ba-4a34-90b6-82b899ea2377
        group: SEATA_GROUP
        cluster: default
        username: nacos
        password: nacos
  store:
    # support: file 、 db 、 redis
    mode: db
    db:
        datasource: druid
        db-type: mysql
        driver-class-name: com.mysql.jdbc.Driver
        url: jdbc:mysql://127.0.0.1:3306/demo-seata?rewriteBatchedStatements=true&useUnicode=true
        user: root
        password: 123456
        min-conn: 5
        max-conn: 100
        global-table: global_table
        branch-table: branch_table
        lock-table: lock_table
        distributed-lock-table: distributed_lock
        query-limit: 100
        max-wait: 5000  
#  server:
#    service-port: 8091 #If not configured, the default is '${server.port} + 1000'
  security:
    secretKey: SeataSecretKey0c382ef121d778043159209298fd40bf3850a017
    tokenValidityInMilliseconds: 1800000
    ignore:
      urls: /,/**/*.css,/**/*.js,/**/*.html,/**/*.map,/**/*.svg,/**/*.png,/**/*.ico,/console-fe/public/**,/api/v1/auth/login

4. 上传config.txt配置到Nacos 执行脚本 \seata-server-1.5.2\script\config-center\nacos\目录右键在 Git Bash Here，执行以下脚本

sh -h nacosIP 。。

5. Srping boot配置seata,  Nacos的seata命名空间增加dataId:  service.vgroupMapping.demo_account_tx_group  值default

seata:
  application-id: ${spring.application.name}
  service:
    vgroup-mapping:
      demo_account_tx_group: default  # 指定事务分组至集群映射关系，即映射到哪一个seata-server集群上，需与server端注册到Nacos的cluster保持一致
  config:
    # support: nacos, consul, apollo, zk, etcd3
    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848
      namespace: 4f4d5421-73ba-4a34-90b6-82b899ea2377
      group: SEATA_GROUP
      username: nacos
      password: nacos
  registry:
    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848
      application: seata-server
      namespace: 4f4d5421-73ba-4a34-90b6-82b899ea2377
      group: SEATA_GROUP
      username: nacos
      password: nacos
  tx-service-group: demo_account_tx_group

 Spring Boot启动项目提示 RM注册成功

RM will register :jdbc:mysql://127.0.0.1:3306/seata_order
2023-09-26 09:34:59.684  INFO 14780 --- [           main] i.s.core.rpc.netty.NettyPoolableFactory  : NettyPool create channel to transactionRole:RMROLE,address:192.168.16.134:8091,msg:< RegisterRMRequest{resourceIds='jdbc:mysql://127.0.0.1:3306/seata_order', applicationId='cloudalibaba-seata-order', transactionServiceGroup='demo_account_tx_group'} >

然后使用@GloalTransation注解使用
