How to query documents with @DBRef using repositories

[aachpach]

I have two collections: Address and Person. Person refers Address class.

@Document
public class Address {

@Id
private ObjectId id;

}

@Document
public class Person {

@Id
private ObjectId id;

@DBRef
private Address add;

//getters and setters
}

Previously, I used MongoTemplate for querying and I was able to query using $id reference. Now, after moving to M3 I am trying to switch my data layer to use spring data's repositories. Can you please advice on how the @DbRef will work with repos? For example, I want to do the following:

public interface AddressRepository extends MongoRepository<Person, ObjectId> {
}

public interface PersonRepository extends MongoRepository<Address, ObjectId> {
List<Person> findByAddress(Address a);
}

Thanks in advance.
