[hibernate-issues] [Hibernate-JIRA] Commented: (HBX-971) generate class-code without overwriting existing extra class-code

Christoph Mayerhofer commented on HBX-971:
------------------------------------------

The drawback of (1) is, that the @Table annotation from the generated super-class must be moved to the (self-created) subclass. I think it would be nicer to just extend the generated class and leave all hibernate-specific code and annotations in the super-class.

> I'm trying to re-generate my class-code from my database-schema without overwriting existing methods from my pojos. I think this isn't possible yet because the java-files are always overwritten after each generation. But there are 2 possibilities to get rid of this problem which are not very convenient in my opinion: 
> (1) subclass the generated class with the @MappedSuperclass annotation and anotate the Subclass with @Entity and @Table.
> (2) modify the generation templates or use the MetaAttribute "classCode" within the ReverseEngineeringStrategy.
> The best approach would be that the generation scripts do not touch the extra class-code from the pojos. Perhaps someone of the developers can verify if this would be possible.
