springboot实现多数据源动态切换（Druid连接池） 1：引入依赖 连接池 切面2：配置yml spring: datasource: druid:db1:type: com.alibaba.druid.pool.DruidDataSource driverClassName: com.mysql.cj.jdbc.Driver url: jdbc:mysql://localhost:3306/test? useUnicode=true&characterEncoding=utf8&serverTimezone=GMT username: root password: root initialSize: 5 minIdle: 5 maxActive: 20 maxWait: 60000 timeBetweenEvictionRunsMillis: 60000 minEvictableIdleTimeMillis: 300000 validationQuery: SELECT 1 FROM DUAL testWhileIdle: true testOnBorrow: false testOnReturn: false
