由异常来看，是由于MongoDB连接超时造成的。于是，往MongoDB上找原因。首先上MongoDB的配置文件：
mongodb.replica-set=192.98.12.242:30007,192.98.12.245:30007 mongodb.hostname=192.98.12.245 mongodb.port=30007 mongodb.connections-per-host=1000 mongodb.threads-allowed-to-block-for-connection-multiplier=200 mongodb.connect-timeout=2000 mongodb.max-wait-time=2000 mongodb.auto-connect-retry=true mongodb.socket-keep-alive=true mongodb.socket-timeout=1500 mongodb.slave-ok=true mongodb.write-number=1 mongodb.write-timeout=1000 mongodb.write-fsync=true mongodb.dbname=shardvectordb mongodb.dbuser= mongodb.dbpassword=
连接时间2秒。然后在定位mongodb的查询，结果为6、7秒。原来是这个原因。然后定位，一个查询为什么耗时那么久呢？
经过排查，原来是查询字段没有创建索引。然后把索引创建，查询几十毫秒，ok问题全部解决。
