已成功使用 play (2.3.8) 反应式 Scala 示例代码来连接并从 mongo 实例创建/读取，但由于我最初配置错误的主机名，无法摆脱 LastError 困扰我的问题。启用调试： logger.reactivemongo=DEBUG 显示详细信息：

and the insert of the POST is fine but for this lastError:

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

db.resetError()在 mongo 中并没有摆脱这一点。从集合中确认插入。代码在这里：https ://github.com/nanothermite/playrctmongo

有什么建议么？

覆盖logback：

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

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

这只会使滥用的 DEBUG 消息静音reactivemongo

如[debug]和[info]前缀所示，这不是错误。

这是 ReactiveMongo 驱动程序在管理连接池和副本集时的详细日志记录。

可以将日志记录级别设置WARNING为禁止此类消息。
