下面配置了master和db1两个数据源,默认primary是master

spring:
  datasource:
    dynamic:
      primary: master #设置默认的数据源或者数据源组,默认值即为master
      strict: false #设置严格模式,默认false不启动. 启动后在未匹配到指定数据源时候回抛出异常,不启动会使用默认数据源.
      datasource:
        master:
          url: jdbc:mysql://192.168.116.130:3306/aaa?useUnicode=true&useSSL=false&characterEncoding=utf8&autoReconnect=true&serverTimezone=CTT
          username: root
          password: 123456
          driver-class-name: com.mysql.jdbc.Driver
        db1:
          url: jdbc:mysql://192.168.116.130:3306/bbb?useUnicode=true&useSSL=false&characterEncoding=utf8&autoReconnect=true&serverTimezone=CTT
          username: root
          password: 123456
          driver-class-name: com.mysql.jdbc.Driver

在service上加上选择数据源的注解DS即可.如果不加默认是master

@Service
@DS("db1")
public class K2ServiceImpl extends ServiceImpl<K2Mapper, K2> implements IK2Service {
	
}
