spring boot 配置多数据源

一、配置pom.xml文件

 <dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>dynamic-datasource-spring-boot-starter</artifactId>
    <version>3.5.2</version>
</dependency>
<dependency>
   <groupId>mysql</groupId>
   <artifactId>mysql-connector-java</artifactId>
   <version>8.0.29</version>
</dependency>

二、apploaction.yml 配置文件

spring:
  datasource:
    dynamic:
      primary: master
      strict: false
      datasource:
        master: #第一个主数据库
          url: jdbc:mysql://127.0.0.1:3306/ceshi_one?characterEncoding=UTF8&autoReconnect=true&serverTimezone=GMT&allowMultiQueries=true
          driver-class-name: com.mysql.cj.jdbc.Driver
          username: root
          password: root
        master1: #第二个数据源
          url: jdbc:mysql://127.0.0.1:3306/ceshi_two?characterEncoding=UTF8&autoReconnect=true&serverTimezone=GMT&allowMultiQueries=true
          driver-class-name: com.mysql.cj.jdbc.Driver
          username: root
          password: root

三、使用方法

第一个数据库源    
@DS("master")
@Override
public Spadmin findOne() {
    QueryWrapper<Spadmin> objectQueryWrapper = new QueryWrapper<>();
    objectQueryWrapper.eq("id",1);
    return spadminMapper.selectOne(objectQueryWrapper);
}

第二个数据源
@DS("master1")
@Override
public Spadmin findOne() {
    QueryWrapper<Spadmin> objectQueryWrapper = new QueryWrapper<>();
    objectQueryWrapper.eq("id",1);
    return spadminMapper.selectOne(objectQueryWrapper);
}
