我正在尝试连接 mLab，但收到此错误:

我按照 mLab 的说明进行操作，但出现了问题。这是我的代码:

        final BasicDBObject[] seedData = createSeedData();
        MongoClientURI uri  = new MongoClientURI("mongodb://<user>:<<password>@ds041861.mlab.com:port/db");
        MongoClient client = new MongoClient(uri);
        DB db = client.getDB(uri.getDatabase());

        DBCollection songs = db.getCollection("texts");

        songs.insert(seedData);// HERE IS THE ERROR

我正在使用 mongo-java-driver-2.13.0-rc0.jar 驱动程序。

正如我在你的照片中看到的，mLab 使用 mongod 3.0.7。您应该使用 mongo-java-driver-3.x.x。 Here是一个链接
