   > 可以看一下改造 MetadataServiceURLBuilder 来支持
   
   目前我们的解决方案是扩展DubboProtocol，重写refer方法，构造完整的调用链路。想问一下MetadataService走所有框架默认filter是否会存在问题？
   `    @Override
       public <T> Invoker<T> refer(Class<T> serviceType, URL url) throws RpcException {
           FilterChainBuilder builder = ScopeModelUtil.getExtensionLoader(FilterChainBuilder.class, url.getScopeModel()).getDefaultExtension();
           return builder.buildInvokerChain(super.refer(serviceType, url), REFERENCE_FILTER_KEY, CommonConstants.CONSUMER);
       }`
