Spring Cloud ContractおよびZuul

Question

Spring Cloud Dalstonを使用して、もちろんZuulを使用するプロキシサービスを構築しました。私は今、Spring Cloud Contractテストを追加して、プロキシサービスが契約順守の観点から期待通りに機能することを確認しようとしています。奇妙なのは、200のステータスコードを返すことができますが、期待される応答本文、コンテンツタイプヘッダーなどが空であり、結果としてテストが失敗するということです。

Zuul機能を使用するサービスのテストに必要なSpring Cloud Contractドキュメンテーションに追加の設定がありますか？ここで

あなたはZuulの場合、あなたには、いくつかのコントローラとの完全なSpringコンテキストだけでなく、モックMVCをする必要がありますhttps://github.com/spring-cloud/spring-cloud-contract/issues/450

/** 
* Abstraction of configuration to test contracts with external microservices which are using a zuul-gateway in between. 
* 
* When a provider of data only allows communication through a Zuul-Gateway, a special way to ensure valid contracts is needed. 
* The Goal is to emulate the Zuul-Interception to be able to use the contracts stored within the providing service. 
* 
* F.e.: Consumer-Service consumes the Provider-Service, but the provider can not be called directly. 
* The Consumer-Service calls an URL with a prefix consisting of the name of the gateway ("gateway") and name of the 
* service (in this example "Provider-Service"). For example: http://gateway/provider/path/to/resource. 
* The contract provided by Provider-Service holds only a part of the provided URL (here: "/path/to/resource"). 
* The resolution of "gateway" and "provider" is done within this class.
