如何防止从java连接到mongodb时登录控制台？

Question

我跟着这个{a1}。这是我的密码

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();
    }
}

下面是输出

Apr 05, 2015 12:17:47 PM com.mongodb.diagnostics.logging.JULLogger log
INFO: Cluster created with settings {hosts=[localhost:27017], mode=SINGLE, requiredClusterType=UNKNOWN, serverSelectionTimeout='30000 ms', maxWaitQueueSize=500}

Got a collection... //my output

根据documentation的说法，它应该像

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

所以，任何人都可以帮助我阻止控制台中的这些日志

Answer 1

多亏了@jyemin 通过使用MongoDB official documentation链接

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

现在控制台中没有日志

Answer 2

通过“com.mongodb.客户端.MongoClient”导入您的Mongo客户端

import com.mongodb.client.MongoClient;
import com.mongodb.client.MongoClients;

import java.util.function.Consumer;
import java.util.logging.Level;
import java.util.logging.Logger;

public class Quick
{

    public static void main(String[] args)
    {
        Logger.getLogger("org.mongodb.driver").setLevel(Level.WARNING);
        try (MongoClient mongo = MongoClients.create())
        {
            mongo.listDatabaseNames().forEach((Consumer<String>) System.out::println);
        }
    }
}

确保你有我写这个答案时的最新版本的驱动程序，3.12.2

<dependency>
        <groupId>org.mongodb</groupId>
        <artifactId>mongo-java-driver</artifactId>
        <version>3.12.2</version>
</dependency>

如果上述方法不起作用，您可能正在使用另一个日志模块，请查看如何关闭该模块，例如，如果您正在使用slf4j，请在资源文件夹中创建一个名为“simpleLogger.properties”的文件，并将此行添加到其中

org.slf4j.simpleLogger.defaultLogLevel = warn

Answer 3

你可以用

logging.level.org.mongodb.driver: ERROR

Answer 4

我试过这个java.util.logging.Logger.getLogger("org.mongodb.driver").setLevel(Level.OFF);

它没有工作，它仍然记录com.mongodb.diagnostics.logging.JULLogger log

我把它改成了JULLogger，它成功了

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