java操作mongoDB的开发，实时插入mongoDB。

一开始是正常的，运行一段时间后开始报错。
长时间运行测试遇到问题，报错信息如下：

怀疑是mongo的连接未关闭导致的，或者连接池用完  ，总之就是连接断开了

第一种java对mongodb的操作可以用如下方法设置：

Mongo conn=new Mongo("127.0.0.1");
MongoOptions option=conn.getMongoOptions();
option.autoConnectRetry=true;
option.socketTimeout=2000;
option.socketKeepAlive=true;

试试设置这两个参数以后可以保持持久连接

option 还可以设置如下这些属性,根据需求选择：

MongoOptions options = new MongoOptions();

            options.autoConnectRetry = true;

            options.connectionsPerHost = (200);

            options.maxWaitTime = (200);

            options.socketTimeout = (200);

            options.connectTimeout = (200);

            options.threadsAllowedToBlockForConnectionMultiplier = (200);

            m = new Mongo(new ServerAddress("10.20.141.22", (200)), options);
