MongoDb + Java 드라이버에 이상한 오류가 발생했습니다.

Question

MongoDb를 데이터베이스로 사용하여 Resteasy 서비스를 구축 중입니다. 몽고 드라이버를 사용하여

public List<DBObject> getAllUsers() throws UnknownHostException, MongoException, FileNotFoundException{ 
    Mongo mongo = new Mongo("localhost"); 
    DBCollection collection = mongo.getDB("eid_security_dev").getCollection("users"); 
    DBCursor cur = collection.find(); 
    List<DBObject> result = new ArrayList<DBObject>(); 
    while (cur.hasNext()){ 

     result.add(cur.next()); 
    } 
    return result; 
} 

: 어떤 DB가 액세스

코드를 :

그것은 내 맥에 있지만, 테스트 서버의 페도라 15에 완벽하게 작동

, 그것은 다음과 같은 오류가 발생합니다 2.7.0 및 mongodb 서버 2.0.0

Answer 1

java.io.IOException: couldn't connect to [eid/67.215.65.132:27017] bc:java.net.ConnectException: Connection timed out 

DB 클라이언트가 Mo에 연결할 수없는 것 같습니다. ngoDB 서버. 몇 가지 조사하기 :

• 은 DB 서버가 정상 작동하는지 확인합니다.

• mongo 쉘을 사용하여 MongoDB 서버가 완벽하게 작동하는지 확인하십시오.

• 67.215.65.132은 공용 IP 주소입니다. localhost은 일반적으로 주소가 127.0.0.1 또는 이와 유사한 루프백 인터페이스로 확인되어야합니다. 공용 IP를 사용하면 DB 서버 포트에 대한 액세스를 차단하는 방화벽 규칙이 있음을 암시 할 수 있으므로 127.0.0.1을 직접 사용해보십시오. 거부되는 대신 연결 시간이 초과되면이 시나리오가 발생할 확률이 높습니다.

Answer 2

See here. 예를 들어, 알 수없는 호스트에 대해이 IP를 반환하는 OpenDNS를 사용하고 있습니다.
