spring:
  autoconfigure:
    exclude: com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceAutoConfigure #因为Spring Boot 框架会自动配置数据源，自动从yml中读取数据源信息，因此我们在配置自定义的数据源的时候，需要exclude = DataSourceAutoConfiguration.class来禁掉数据源的自动配置
  datasource:
    dynamic:
      primary: mysql  #设置默认的数据源或者数据源组,默认值即为mysql
