从java连接到mongodb时如何防止登录控制台？
你好
我正在尝试学习mongo-java driver.i，然后按照这个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 INFO: Cluster created with settings {hosts=[localhost:27017], mode=SINGLE, requiredClusterType=UNKNOWN, serverSelectionTimeout='30000 ms', maxWaitQueueSize=500} Apr 05, 2015 12:17:47 PM com.mongodb.diagnostics.logging.JULLogger log INFO: No server chosen by ReadPreferenceServerSelector{readPreference=primary} from cluster description ClusterDescription{type=UNKNOWN, connectionMode=SINGLE, all=[ServerDescription{address=localhost:27017, type=UNKNOWN, state=CONNECTING}]}. Waiting for 30000 ms before timing out Apr 05, 2015 12:17:47 PM com.mongodb.diagnostics.logging.JULLogger log INFO: Opened connection [connectionId{localValue:1, serverValue:3}] to localhost:27017 Apr 05, 2015 12:17:47 PM com.mongodb.diagnostics.logging.JULLogger log INFO: Monitor thread successfully connected to server with description ServerDescription{address=localhost:27017, type=STANDALONE, state=CONNECTED, ok=true, version=ServerVersion{versionList=[2, 6, 1]}, minWireVersion=0, maxWireVersion=2, maxDocumentSize=16777216, roundTripTimeNanos=389140} Apr 05, 2015 12:17:47 PM com.mongodb.diagnostics.logging.JULLogger log INFO: Opened connection [connectionId{localValue:2, serverValue:4}] to localhost:27017 { "_id" : { "$oid" : "55201cec68fb70b6affba026"} , "name" : "prasad" , "password" : "123456"} //This is my output Apr 05, 2015 12:17:47 PM com.mongodb.diagnostics.logging.JULLogger log INFO: Closed connection [connectionId{localValue:2, serverValue:4}] to localhost:27017 because the pool has been closed. Got a collection... //my output
根据文档，它应该打印出来
{ "_id" : { "$oid" : "55201cec68fb70b6affba026"} , "name" : "prasad" , "password" : "123456"} Got a collection...
那么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。
