play (2.3.8) 反応性 Scala サンプル コードを使用して mongo インスタンスに接続し、作成/読み取りを行いましたが、最初にホスト名を誤って構成したため、LastError を振ることができませんでした。デバッグを有効にする: logger.reactivemongo=DEBUG は詳細を表示します:

[debug] application - Successfully inserted with LastError: reactivemongo.core.commands.LastError: DatabaseException['empty lastError message']

db.resetError()in mongo はこれを取り除きません。コレクションから挿入物を確認。コードはこちら: https://github.com/nanothermite/playrctmongo

助言がありますか？

以下でオーバーライドlogbackします。

<logger name="reactivemongo.api.Failover2">
    <level value="INFO"/>
</logger>

<logger name="reactivemongo.core.actors">
    <level value="INFO"/>
</logger>

これにより、不正な DEBUG メッセージのみが沈黙します。reactivemongo
