SpringBoot连接MySql主从配置 读写分离

SpringBoot连接MySql主从配置 主从读写分享

1、添加maven依赖

<dependency>
    <groupId>org.apache.shardingspheregroupId>
    <artifactId>sharding-jdbc-spring-boot-starterartifactId>
    <version>4.1.1version>
dependency>

2、springboot yml文件配置

spring:
  shardingsphere:
    datasource:
      names: master,slave1,slave2
      # 主数据源
      master:
        type: com.alibaba.druid.pool.DruidDataSource
        driver-class-name: com.mysql.cj.jdbc.Driver
        url: jdbc:mysql://ip:port/mydb?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&useSSL=false
        username: root
        password: 123456
      # 从数据源
      slave1:
        type: com.alibaba.druid.pool.DruidDataSource
        driver-class-name: com.mysql.cj.jdbc.Driver
        url: jdbc:mysql://ip:port/mydb?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&useSSL=false
        username: root
        password: 123456
      slave2:
        type: com.alibaba.druid.pool.DruidDataSource
        driver-class-name: com.mysql.cj.jdbc.Driver
        url: jdbc:mysql://ip:port/mydb?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&useSSL=false
        username: root
        password: 123456
    masterslave:
      # 读写分离配置
      load-balance-algorithm-type: round_robin
      # 最终的数据源名称
      name: dataSource
      # 主库数据源名称
      master-data-source-name: master
      # 从库数据源名称列表，多个逗号分隔
      slave-data-source-names: slave1,slave2
    props:
      # 开启SQL显示，默认false
      sql:
        show: true
