Zuulを使用してリクエストを内部サービスにルーティングするSpringブートゲートウェイプロジェクトがあります。これらのサービスはEurekaを使用して検出されます。Spring Zuul returned 502
これはほとんどのシナリオで機能します。しかし、ゲートウェイから502を返すいくつかの長い要求があります。基礎となるサービスが実際に要求を完了しています。そして、ゲートウェイへの要求はその間に開いたままです。
どちらのリクエストもかなり長いです。 1つは、約5-10秒かかる小さなプロセスを実行します。もう1つはファイルのアップロードです。どちらの要求も、ボディを返さないメソッドPOSTです。これがズールに影響するだろうか？
これはログからのスタックトレースです。

私たちはSpring Boot 1.4.1とSpring Cloud Camdenを使用しています。
Spring Gatewayがこれらのリクエストをタイムアウトさせないようにするにはどうすればよいですか？
がそのスタックトレースによりませんか？ 'ribbon.ConnectTimeout = 3000'を増やしてみましたか？ – Jeff
@Jeff完全なスタックトレースを追加しました。私は 'ribbon.ConnectTimeout'を' 3000'から増加させようとしていません。私はそれがバックエンドサーバーとの接続を行う前の時間だと理解しています。しかし、この接続は迅速に行われます。 –
あなたは直接サービスにアクセスできて、はいの場合は、タイムアウト番号で再生して正しいものを取得するだけであると仮定します。 –
