Description

Maciej Walkowiak opened DATAJDBC-292 and commented

Recently introduced AggregateReference currently does seem to work with many to many scenarios while for simple referencing entities by id it would be sufficient.

For example there are two classes Book and Author. I think many to many mapping could be express in following way:

class Book {
   ...
   Set<AggregateReference<Author,Long>> authors;
}
