#nacos集成nacos并配置mysql数据源

1. 所需依赖

  <!--seata 分布式事务-->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-seata</artifactId>
        </dependency>

2. 打开seata目录，找到sql文件

3. 打开配置文件配置数据源

我们需要修改的是application.yml文件，另一个带example的是官方提供的模板文件

4. 我们打开，然后将以下信息进行添加，可复制后进行修改

这里面的配置需要相互对应的修改，不能乱改

  port: 7091

spring:
  application:
    name: seata-server

logging:
  config: classpath:logback-spring.xml
  file:
    path: ${user.home}/logs/seata
  extend:

    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848

5. 打开nacos配置中心，将上面配置的文件加入到配置中心

store.db.datasource=druid
store.db.dbType=mysql
store.db.driverClassName=com.mysql.cj.jdbc.Driver
store.db.url=jdbc:mysql://localhost:3306/seata?useUnicode=true&rewriteBatchedStatements=true
store.db.user=root
store.db.password=root
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


# 和微服务模块的seata.tx-service-group保持一致
service.vgroupMapping.train-group=default
service.default.grouplist=127.0.0.1:8091

6. 配置idea中的模块配置文件

将以下配置添加到配置中，注意，配置文件和上面的相互对应，如果需要修改的话，请将其他的配置文件全部修改

seata: # seata配置
  tx-service-group: train-group # 事务组
  service: # seata服务
    vgroup-mapping: # 事务组映射
      train-group: default # 事务组名称,需要和tx-service-group一致
    grouplist: # 注册中心
      default: 127.0.0.1:8091 #seata服务地址
  registry: # 注册中心
    type: nacos # 注册中心类型
    nacos:
      application: seata-server # seata服务名称
      server-addr: 127.0.0.1:8848 # 注册中心地址
      group: SEATA_GROUP # 注册中心组
      namespace: train # 注册中心命名空间
      username:
      password:
  config:
    type: nacos
    nacos:
      server-addr: 127.0.0.1:8848
      group: SEATA_GROUP
      namespace: train
      dataId: seataServer.properties
      username:
      password:
