マイfeignClientがあるエラーを取得していますFeignClientを使用して他のアプリケーションを襲ったとき、彼らは

PCF

中ユーレカServerで見ることができます。ここ

を掲示しながら、私はまた、春のセキュリティが有効になっており、それはまた、匿名の要求を可能にしたサービスを再命名しました。

protected void configure(HttpSecurity http) throws Exception { 
     http.httpBasic().disable().authorizeRequests() 
     .antMatchers("/my-feign-services/**").anonymous() 
     .and() 
     .authorizeRequests().anyRequest() 
     .authenticated().and().csrf().disable(); 
    } 

なぜ、FeignClientがPCFで動作しないのか。ローカルホストでは正常に動作し、2つのサービス間で簡単に通信できますが、PCFで失敗することがあります

設定クラスでFeignLoggerを使用し、FeignクライアントでFeign Loggingを有効にしました。場所はログに正しく入っていますが、エラー302と：の内容で失敗しています。

更新：

それが働いていたコンフィギュレーションクラスにURLを追加した後。プラットフォームチームがCloud FoundryでSpring Cloudサービスを取得するまでは、ギャップを埋めることができます。

Answer 1

新しいダミーサービスを追加してデバッグしようとしましたが、同じFeignExceptionでも失敗しました。 PCFのServiceレジストリに問題があるようです。私はバックアップコードを持っていて、他のコードをこれに移行してテストしたところ、うまくいきました。私はエラーなしでMS - MS通信を行うことができ、応答も受信されました。

Answer 2

302エラーはリダイレクトを示します。あなたはLocationヘッダーが何を応答しているのか見てみることができますか？リダイレクトに従うように設定されていない可能性があります。
