   ```java
     
     consumer端：
   
      //创建dubbo泛化异步引用
       public static synchronized ReferenceConfig<GenericService> 
createReference(TopicInfoImmutable topicInfoImmutable) {
           ReferenceConfig<GenericService> reference = new ReferenceConfig<>();
           reference.setInterface(topicInfoImmutable.getInterfaceName());
           reference.setGroup(topicInfoImmutable.getGroup());
           reference.setVersion(topicInfoImmutable.getVersion());
           reference.setRetries(1);
   
           reference.setGeneric(CommonConstants.GENERIC_SERIALIZATION_GSON);
           reference.setAsync(true);
           reference.setCheck(false);
           reference.setFilter("-sentinel.dubbo.consumer.filter");
           //timeout改为在调用时设置
           //reference.setTimeout((int) 
topicInfoImmutable.getConsumeTimeoutMills());
           return reference;
       }
   
   //执行泛化异步调用 
   genericService = createReference（topicInfoImmutable）；
   CompletableFuture completableFuture = RpcContext.getContext().asyncCall(
                           () -> genericService.$invoke(info.getMethodName(), 
info.getArgsType(), args)
                   );
                   final Object invoke = completableFuture.get();
   
   
     //provider端
    
   常规方式，使用@DubboService暴露一个接口
   @DubboService
   public class MyServiceImpl implements MyService{
      Result doXX();
   }
   
   ```
   
   然后C,P端就开始刷那个获取元数据失败的报错了。
