[英]MongoDb and morphia password and username
playing around with this and cannot get a grip 玩这个,不能抓
on how to connect with password. 关于如何使用密码连接。
In MongoDb it's quite easy to understand but when i use morphia it's not 在MongoDb中,它很容易理解,但是当我使用吗?
so quite obvious because documentation is minimal or i missed it. 非常明显,因为文档很少,或者我错过了。
I already have a Collection with 5 documents. 我已经有一个包含5个文档的收藏集。
Can i apply a user/pass on that one? 我可以申请一个用户/通行证吗?
How can i modify this code so logging uses a username and password? 如何修改此代码,以便日志记录使用用户名和密码?
Took the code from this post (Thanks @Lennart Koopmann) 摘自这篇文章的代码(感谢@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;
}
}
maybe you could use the following code: 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");
