caofei88 opened a new issue #8097:
URL: https://github.com/apache/dubbo/issues/8097


   
背景：provider起两个服务，使用parameters参数，consumer中去订阅，发现在Directory拿到List<Invoker<T>>与nacos注册中心不一致
   问题定位代码在类DubboCloudRegistry  154行 方法subscribeURLs里面调用
   172的这行代码有问题：
      List<URL> subscribedURLs = this.cloneExportedURLs(subscribedURL, 
serviceInstances);
   拿到的url对象跟nacos中metadata信息不一致，  多次debug执行会产生不一样的结果 （dubbo 2.7.6 2.7.8同样存在）
   
   demo地址见：[email protected]:caofei88/dubbo-spring-cloud-demo.git
   
    部分provider配置
     provider:                                      
       filter: tracing
       parameters:
         dcCode: "dcCode1"         
    
     provider:
       filter: tracing
       parameters:
         dcCode: "dcCode2"
