12.Seata配nacos

59

一、配置导入nacos

1.进入资源目录（上一篇下载的资源文件）的config-center


2.修改config.txt文件


3.事务分组修改


service.vgroupMapping.[客户端会用到这个值]=[服务端的会用到这个值]


4.存储修改为db(数据库地址为上一篇创建的数据库地址)


5.启动nacos并创建命名空间


6.创建配置文件


7.配置文件中添加，“config.txt”中的内容，我就添加了修改部分。


service.vgroupMapping.cd=lry


store.mode=db

store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.jdbc.Driver
store.db.url=jdbc:mysql://127.0.0.1:3305/seata-server?useUnicode=true&rewriteBatchedStatements=true
store.db.user=root
store.db.password=123456
store.db.minConn=5
store.db.maxConn=30
store.db.globalTable=global_table
store.db.branchTable=branch_table
store.db.distributedLockTable=distributed_lock
store.db.queryLimit=100
store.db.lockTable=lock_table
store.db.maxWait=5000

二、服务的配置

1.修改配置文件



注：cluster: lry 为上面第三步事务分组填写的值

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: e2b58124-d455-4cbe-a0fb-f9fd22966660
      group: DEFAULT_GROUP
      username: nacos
      password: nacos
      ##if use MSE Nacos with auth, mutex with username/password attribute
      #access-key: ""
      #secret-key: ""
      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
      group: DEFAULT_GROUP
      namespace: e2b58124-d455-4cbe-a0fb-f9fd22966660
      cluster: lry
      username: nacos
#  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

2.启动服务的




三、客户端配置

1.客户端数据库导入资源文件中的mysql.sql


2.导入后的表结构


3.导入依赖

4.修改配置文件（这的 tx-service-group: cd 就是第一步的第3步设置的值）


server:
  port: 5002
spring:
  application:
    name: seata-stock
  datasource:
    url: jdbc:mysql://127.0.0.1:3305/stock?serverTimezone=UTC&characterEncoding=utf-8
    username: root
    password: 123456
    driver-class-name: com.mysql.cj.jdbc.Driver

  cloud:
    #当前项目注册到注册中心
    nacos:
      discovery:
        server-addr: 192.168.152.1:8848
        username: nacos
        password: nacos
        group: DEFAULT_GROUP
mybatis:
  mapper-locations: classpath:mybatis/mapper/*.xml

#服务器配置的信息
seata:
  enabled: true
  #事务分组
  tx-service-group: cd
  config:
    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848
      namespace: e2b58124-d455-4cbe-a0fb-f9fd22966660
      group: DEFAULT_GROUP
      username: nacos
      password: nacos
      data-id: seataServer.properties
  registry:
    type: nacos
    nacos:
      application: seata-server
      server-addr: 127.0.0.1:8848
      group: DEFAULT_GROUP
      namespace: e2b58124-d455-4cbe-a0fb-f9fd22966660
      cluster: default
      username: nacos

5.创建数据源配置类（非常重要，不创建事务不回滚）


6.编写业务类，调用openfeign接口
