apache-commons-net ライブラリを使用して、FTP over SSL (SFTP ではない) または FTPS を実行できる非常に小さな Java プログラムがあります。このプログラムを作成した理由は、クライアント マシンが FTP over SSL ( OOTB ) をサポートしない AIX 5.3 であり、FTP ホスト マシンが FTP over SSL のみを有効にして FileZilla サーバーを実行しているためです。プログラムは問題なく正常に動作しますが、生成されるログの量は膨大です。私の質問は、ロギングの量を制御する方法はありますか?
(繰り返しますが、このプログラムは、私のミニマリストの要件に対してはまったく問題なく動作します)
以下は私のコードのスニペットです

私はjava.utils.logging.Logger
独自のロギング目的で使用していますが、ログの行は、apache-commons-net
ライブラリ メソッド自体によって生成される多数のログ行によって難読化されています。
繰り返しになりますが、質問は、「ライブラリ自体のこのロギング動作を制御する方法はありapache-commons-net
ますか?使用できる方法または設定する必要があるフラグはありますか??」
アップデート:
ついにロギングを制御できるようになりました ( Flavioに感謝します)。私がしなければならなかったSystem.setProperty("javax.net.debug", "false");
のは、コードに含めることだけでした。System.setProperty("javax.net.debug", "ssl");
デバッグレベルのログを有効にするように最初に設定しました。これで、ログははるかに短く正確になりました。また、ログが commons-net ライブラリからのものではなく、javax.net
. ログははるかに短く、以下のようになります-
