MongoDb和morphia密码和用户名

Question

玩这个,无法掌握
如何连接密码.

在MongoDb中它很容易理解但是当我使用morphia时它并不
那么明显,因为文档很少或者我错过了它.

我已经有一个包含5个文档的Collection.
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？

从这篇文章中获取代码(Thanks @Lennart Koopmann)

        public Datastore getDb() {

            return db;
        }   
    }

也许你可以使用以下代码:

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");
