Mongodb read timee out異常解決辦法

完整異常資訊：

最後的read timed out是關鍵
異常原因是在進行資料操作時過長時間沒有返回結果。

解決辦法：設定SocketTimeout

spring配置如下：

  <mongo:options connections-per-host="500" socket-timeout="5000" max-wait-time="5000"                       threads-allowed-to-block-for-connection-multiplier="1000"                       connect-timeout="30000"/>
