从java连接到mongodb时如何防止登录控制台？

Question

您好
我正在尝试学习mongo-java driver.i遵循此mongodb文档.以下是我的代码

public class JMongoDBCDemo
{
    MongoClient mongoClient;
    DB db;
    DBCollection coll;
    public JMongoDBCDemo()
    {
        MongoClient mongoClient = new MongoClient( "localhost" , 27017 );
        db = mongoClient.getDB( "messenger" );
        coll = db.getCollection("users");
        DBObject myDoc = coll.findOne();
        System.out.println(myDoc);
        mongoClient.close();
        System.out.println("Got a collection...");
    }
    public static void main(String[] args){
            JMongoDBCDemo mongoDemo = new JMongoDBCDemo();
    }
}

以下是输出

Apr 05, 2015 12:17:47 PM com.mongodb.diagnostics.logging.JULLogger log

Got a collection... //my output

根据文档,它应该打印出来

{ "_id" : { "$oid" : "55201cec68fb70b6affba026"} , "name" : "prasad" , "password" : "123456"}
Got a collection... 

所以任何人都可以帮我防止这些日志在控制台中.

感谢@jyemin 使用MongoDB官方文档链接

Logger mongoLogger = Logger.getLogger( "org.mongodb.driver" );
mongoLogger.setLevel(Level.SEVERE); 

现在控制台中没有日志.
