how to prevent logging on console when connected to mongodb from java?

Question

Hi
i am trying to learn mongo-java driver.i followed this mongodb documentation. The below is my code

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();
    }
}

the below is the output

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

Got a collection... //my output

according to documentation it should print like

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

So can any one please help me to prevent these logs in console.

Answer 1

Thanks to @jyemin By using MongoDB official documentation link

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

Now no logs are there in the console.

Answer 2

i tried this java.util.logging.Logger.getLogger("org.mongodb.driver").setLevel(Level.OFF);

it not worked, it still logs com.mongodb.diagnostics.logging.JULLogger log

I changed it to JULLogger and it worked

java.util.logging.Logger.getLogger("JULLogger").setLevel(Level.OFF);
