3.4 ログレベルの変更方法
logback.xml の初期設定では、bspdf.log、bsxml.log、bs.log、other.log、axis2.log、jackrabbit.log は WARNレベル以上のログのみ出力するように設定されていますが、
動作確認や問題発生時の原因調査のためにログレベルを変更することが可能です。
変更の手順は以下のとおりです。
- logback.xml をテキストエディタで開き、各ログ設定の <logger>タグのlevel属性の値を「WARN」から「INFO」または「DEBUG」へ手動で変更してください。
- 設定変更を反映させるためには、アプリケーションを再起動して logback.xml を再読み込みする必要があります。
- 動作検証完了後は設定を元に戻してください。大量のログ出力はパフォーマンス低下の原因となりますのでご注意ください。
