Question

玩这个并且无法获得抓地力关于如何连接密码。

在MongoDb中，它很容易理解，但是当我使用morphia时，它并非如此很明显，因为文档很少或我错过了它。

我已经收藏了5份文件我可以申请那个用户/通行证吗？

如何修改此代码，以便日志记录使用用户名和密码？

从这篇文章中取出代码（谢谢@Lennart Koopmann）

public final class MongoConnectionManager {

 private static final MongoConnectionManager
 INSTANCE = new MongoConnectionManager();
 private final Datastore db;
 public static final String DB_NAME = "mongo_database";

 private MongoConnectionManager() {
            try {
                Mongo m = new Mongo("localhost", 27017);
            db = new Morphia().map(UserData.class)
     .map(Statistic.class)
     .map(FriendList.class)
     .map(ServerData.class)
     .map(BatchData.class).createDatastore(m, DB_NAME);

                db.ensureIndexes();
            }
            catch (Exception e) {
                throw new RuntimeException("Error initializing mongo db", e);
            }
        }

        public static MongoConnectionManager instance() {
            return INSTANCE;
        }

        public Datastore getDb() {

            return db;
        }   
    }

Answer 1

也许您可以使用以下代码：

Morphia morphia = new Morphia();
ServerAddress addr = new ServerAddress("host", 27017);
List<MongoCredential> credentialsList = new ArrayList<MongoCredential>();
MongoCredential credentia = MongoCredential.createCredential(
    "username", "dbname", "password".toCharArray());
credentialsList.add(credentia);
MongoClient client = new MongoClient(addr, credentialsList);
datastore = morphia.createDatastore(client, "dbname");

Answer 2

createDatastore(m, DB_NAME, username, password)

已经引入了{p> This重载方法here。

也许您使用的是较旧的Moprhia客户端？

MongoDb和morphia密码和用户名
