Support interface inheritance mapping ------------------------------------- Key: HHH-4413 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4413 Project: Hibernate Core Issue Type: Improvement Components: annotations Reporter: Steve Ebersole Attachments: hibernate3-annotations-3.1beta5-3896-3948.diff, hibernate3-annotations-3.1beta5-3896-4138.diff 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/#inheritanc... 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 :)
