[hibernate-issues] [Hibernate-JIRA] Commented: (ANN-528) avoid auto import of superclasses to avoid inheritance mapping

Emmanuel Bernard commented on ANN-528:
--------------------------------------

If your framework closed the entity source, there should be a reason. 
I gues the standard way to do that would be to override the mappings completly using metadata-complete=true, but it creates duplication.

I don't exactly understand what the annotation is supposed to do, can you elaborate?

> It is not possible to avoid inheritance mapping if the superclass of a entity is also a entity. 
> Background: A framework provides a basic mapping of a entity, but I want to extend that. 
> With annotations it is not possible to just map my extended version and have the superclass behave like a MappedSuperclass. This behaviour is  acceptable but it is not possible to override a the id generation.
> So it might be better to have a new annotation (e.g. @RootEntity(mapSuperclass=true)) to avoid auto import of the entity superclass. With that approach it would be easier to create modules and frameworks
