MongoRepository custom Id

[Manuel Doncel Martos]

Hi to all,

This is my first personal (and no personal) project with MongoDB and I have one doubt that you all may have a solution for it.

I have the following MongoDB Repository

public interface TeamRepository extends MongoRepository<Team, TeamId> {
    ....
}

And the following classes:

public abstract class DbId implements Serializable {
    @Id
    private final String id;

    public DbId(final String id) { this.id = id;}

    public String getId() { return id;}
}

public class TeamId extends DbId {

    public TeamId(final String id) {
        super(id);
    }
}

As you can see, I have a custom id for the repository (I have MongoRepository<Team, TeamId> instead of something like MongoRepository<Team, String>). The TeamId class, only contains a String id. 

When I am trying to save a Team object, with teamRepository.save(team), I get an error saying that MongoDB does not know how to generate TeamId. Any clue?
