[GitHub] [dubbo] IceNiro commented on issue #9748: 使用group作为环境隔离,正常环境访问问题

IceNiro commented on issue #9748:
URL: https://github.com/apache/dubbo/issues/9748#issuecomment-1063722863


   Environment
   Dubbo version: 2.7.7
   Operating System version: Linux centos 6.7
   Java version: 1.8
   
   使用group做环境隔离
   需求:
   当迭代环境中未部署对应的服务是,需要去调用稳定环境;若有部署对应服务,则调用迭代环境的提供者。
   方案:
   1 稳定环境提供者和消费者都没有group标记
   2 迭代环境对应提供者的group标记;消费使用通配符 *
   问题:
   因为 消费者 使用 通配符 会触发 toMergeInvokerList;但是只存在一个稳定环境的提供者,会默认使用 MergeableClusterInvoker 调用且无法拓展;然后 会出现 :Not found exported service: */com.xxxx.xxxx.ucenter
   
   可以如何解决这个问题?
