OpenShift 3 Java Mongodb

Question

我正在使用带有mongodb的openshift 3。我在mongodb中使用Spring data。但是我无法在Openshift上连接到mongodb。我正在使用这样的代码：

MongoCredential credential = MongoCredential.createMongoCRCredential(USER, DB_NAME, PASSWORD.toCharArray());
ServerAddress address = new ServerAddress("localhost", 27017);
List<MongoCredential> list = Collections.singletonList(credential);
return new MongoClient(address, list); 

但我有

Answer 1

如果您没有使用本地mongodb运行自定义镜像，而是从应用程序模板创建了一个(持久的) mongodb，请在“application”和“services”下查看有关主机名和IP的其他详细信息。
