[GitHub] [dubbo] fangzhenhe opened a new issue #9460: 关于dubbo嵌套调用，消费者过滤器消除RpcContext导致的最早调用的消费者丢失RpcContext。链路追踪采集不到问题

   解释：order是最外层dubbo的调用，distribute是里层的dubbo调用。client代表消费者，server代表提供者。before可以理解成拦截方法前，after理解成拦截方法后。
   问题：在里层的dubbo调用后将前一个未执行完毕的dubbo消费的RpcContext消除覆盖，导致上未执行完的dubbo消费传递上下文给提供方的时候丢失RpcContext。

   DUBBO3 的 URL 设计上 感觉很坑， RPCServiceContext的话 如果出现嵌套调用， 要先保存上下文， 然后 调用其它RPC 服务， 然后恢复上下文。 尽量不要再 Consumer 的 Filter中 发起其它 RPC 调用。
