[hibernate-issues] [Hibernate-JIRA] Commented: (ANN-9) Support interface inheritance mapping

[Barney Boisvert (JIRA)]

Barney Boisvert commented on ANN-9:
-----------------------------------

I used annotation/hbm mix on a project and it worked fine, though it was a bit ungainly to have to deal with mapping data in two such disparate places.  Having interface support with annotations would definitely be better, but mixed-mode does work as a stopgap.

> It should be possible to create a mapping with interfaces, as described by the documentation here: http://www.hibernate.org/hib_docs/v3/reference/en/html_single/#inheritance-tableperclass
> Specifically right now it is impossible to annotate interfaces and according to HBX-231 even if you could @Entity is only meant to get used on classes so the question becomes "what do you annotate it with?"
> As I pointed out here http://forum.hibernate.org/viewtopic.php?p=2238824#2238824 the additional problem seems to be that XDoclet doesn't support interface annotation either (http://opensource.atlassian.com/projects/xdoclet/browse/XDT-1345) so I'm left without a workaround.
> I can't convert the interfaces to abstract classes because I implement multiple interfaces in my application and Java does not do multiple inheritance.
> If you know of a nice workaround, please let me know :)
