Review Comment:
Thank you so much for your review! But it seems that the logic below can't
be realized by lambda.
https://github.com/apache/dubbo/blob/33c2d1250194104dae4f446783926ef2429478e1/dubbo-config/dubbo-config-api/src/main/java/org/apache/dubbo/config/metadata/ConfigurableMetadataServiceExporter.java#L215-L231,
now it is `ProtocolConfig` first `List<ProtocolConfig>` second in one
`ProviderConfig`.
```
Stream<ProviderConfig> providerConfigStream = moduleModels.stream()
.map(ModuleModel::getConfigManager)
.map(ModuleConfigManager::getProviders)
.filter(CollectionUtils::isNotEmpty)
.flatMap(Collection::stream);
protocol = providerConfigStream
.map(ProviderConfig::getProtocol)
.filter((protocolConfig) -> protocolConfig != null)
.map(ProtocolConfig::getName)
.findFirst()
.orElse("");
if (StringUtils.isEmpty(protocol)) {
protocol = providerConfigStream
.map(ProviderConfig::getProtocols)
.filter(CollectionUtils::isNotEmpty)
.flatMap(Collection::stream)
.map(ProtocolConfig::getName)
.filter(StringUtils::isNotEmpty)
.findFirst()
.orElse("");
}
```
After using lambda, it becomes `ProtocolConfig` in all `ProviderConfig`
first, then `List<ProviderConfig>` in all `ProviderConfig`.
Do you have a better way to refactor this logic in lambda? Thank you.
