How to query MongoDB by id without MongoOperations::findById

[Ben Blum]

Hi,

I'm trying to get Spring to generate a MongoDB query method which looks to match within an array:

public class Cab {
@DBRef 
List<Passenger> passengers;
}

public interface CabRepository {
  Cab findByPassengersId(String id);
}

But the generated query looks for cab.passengers._id, rather than cab.passengers.$id, as it should for the DBRef to resolve correctly:


2012-08-03 14:10:39,608 [SimpleAsyncTaskExecutor-1] DEBUG org.springframework.data.mongodb.repository.query. MongoQueryCreator - Created query Query: { "passengers._id" : "C"}, Fields: null, Sort: null

What am I doing wrong?

Thanks,
Ben
