単純な SFTP チャネル アダプターを実装して、任意のファイル名のファイルを受け入れるようにしようとしています (ファイル名の重複を許可するため)。最初のポーリングでは、ファイルは SFTP サーバー ディレクトリからローカル ディレクトリに転送され、このチャネルにサブスクライブされているサービス アクティベーターはメッセージを受信できますが、2 回目は SFTP サーバーに同じ名前のファイルを保持すると、ファイルは転送されましたが、サービス アクティベーターはメッセージを取得できませんでした。ローカル フィルターを実装しようとしましたが、無限ループ (ファイルのポーリングとメッセージの作成) に陥りました。
