MongoDb + Java驱动程序奇怪的错误

我正在用MongoDb作为数据库构建Resteasy服务。MongoDb + Java驱动程序奇怪的错误

它完全在我的Mac，但在测试服务器中的Fedora 15，它提出了一个错误如下：

的代码访问DB是：

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; 
}

使用蒙戈司机2.7.0和mongodb服务器2.0.0

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

看来你的DB客户端无法连接到Mo ngoDB服务器。要调查的几件事：

确保您的数据库服务器已启动并正在运行。
使用mongo shell来验证您的MongoDB服务器是否完全正常运行。
67.215.65.132是一个公共IP地址。 localhost通常应解析为地址为127.0.0.1或类似地址的回送接口。直接尝试使用127.0.0.1，因为使用公共IP可能意味着存在阻止访问数据库服务器端口的防火墙规则。连接超时而不是被拒绝使得这种情况很可能发生。

DB启动并运行，mongo shell工作正常，127.0.0.1给了我相同的结果。我不知道67.215.65.132来自哪里:( –

这个错误在我重新安装整个服务器并且这次使用127.0.0.1之后就消失了....感谢您的帮助:) –

See here。例如，您正在使用OpenDNS，它为未知主机返回此IP。
