可直接使用 ReplicationConnectionProxy 多主多从策略，将同区域MySQL实例配置为SOURCE，其他区域MySQL实例配置为REPLICA)，配置方式如下： `jdbc:mysql:replication://root:root123456@(host=localhost,port=3309,type=SOURCE),root:root123456@(host=localhost,port=3310,type=SOURCE),root:root123456@(host=localhost,port=3311,type=REPLICA),root:root123456@(host=localhost,port=3312,type=REPLICA)/my_schema?ha.loadBalanceStrategy=random` 参考代码：com.mysql.cj.conf.ConnectionUrlParser 配置效果：  优点：无入侵，完全使用MySQL驱动原生实现和配置；可在实现多区域多活、同区域优先的前提下，支持LoadBalance策略。 缺点：功能仅限于多区域多活、同区域优先，如果需要指定区域优先级等定制策略，还是需要自定义扩展。
