Question

已成功使用play（2.3.8）反应式Scala示例代码连接并创建/读取mongo实例但无法动摇LastError，因为我最初错误配置了主机名。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']

mongo中的

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

有什么建议吗？

Answer 1

在logback中覆盖：

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

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

这会使reactivemongo

的滥用DEBUG消息无声

Answer 2

正如[debug]和[info]前缀所示，这不是错误。

当ReactiveMongo驱动程序管理连接池和replicaset时，这是一个详细的日志记录。

可以将日志记录级别设置为WARNING以禁止此类消息。

成功的CRUD但是对于lasterror in play reactivemongo 2.3.8
