Spring Data Mongodb & Spring Boot - autowiring MongoRepository from Mongolab

Question

Let say I have a simple mongoRepository below:

public interface LettersRepository extends MongoRepository<Posts, String> { 

    }

I'm connecting to Mongolab. The collection name on Mongolab has to be 'letters' for the autowiring to work.

Now, I don't want to call my collection on Mongolab 'letters'. I want to call it 'mails'.

How do I use annotations to configure that the autowiring will point to the 'mails' collection instead?

I tried the annotation @Repository(value="mails") above the interface but it does not work.

Answer 1

The mapping to Mongo collections depends on your domain object, not the repository. If you want your Posts class to be stored in the collection mails , annotate it with @Document :

@Document(collection = "mails")
public class Posts {
}

See the Mapping chapter in the documentation for details.
