   错误现象：启动 Rest Sample 时报错
   
   错误代码：
   [rest_protocol.go](https://github.com/apache/dubbo-go/blob/config-enhance/protocol/rest/rest_protocol.go)
   ```
   // Export export rest service
   func (rp *RestProtocol) Export(invoker protocol.Invoker) protocol.Exporter {
   	url := invoker.GetURL()
   	serviceKey := url.ServiceKey()
   	exporter := NewRestExporter(serviceKey, invoker, rp.ExporterMap())
   	id := url.GetParam(constant.BEAN_NAME_KEY, "")
           // error ：此处获取 rest config 为空
   	restServiceConfig := rest_config.GetRestProviderServiceConfig(id)
   	if restServiceConfig == nil {
   		logger.Errorf("%s service doesn't has provider config", url.Path)
   		return nil
   	}
   	rp.SetExporterMap(serviceKey, exporter)
   	restServer := rp.getServer(url, restServiceConfig.Server)
   	for _, methodConfig := range restServiceConfig.RestMethodConfigsMap {
   		restServer.Deploy(methodConfig, server.GetRouteFunc(invoker, methodConfig))
   	}
   	return exporter
   }
   ```
