JPA map collection of Enums

Question

Is there a way in JPA to map a collection of Enums within the Entity class? Or the only solution is to wrap Enum with another domain class and use it to map the collection?<

Answer 1

Collections in JPA refer to one-to-many or many-to-many relationships and they can only contain other entities. Sorry, but you'd need to wrap those enums in an entity. If you think about it, you'd need some sort of ID field and foreign key to store this information anyway. That is unless you do something crazy like store a comma-separated list in a String (don't do this!).
