[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5950) Make @UniqueConstraint inheritable

[Emmanuel Bernard (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5950?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=40059#action_40059 ] 

Emmanuel Bernard commented on HHH-5950:
---------------------------------------

Hum, I've never been a big fan of this approach of sticking physical concerns on the logical @MappedSuperclass. 
It also put some expectations on how your can factor things like a template id generator defined partially on the superclass.

What's your use case? Do you really have a wide subtree of subclasses?

> It would be really nice to be able to define a @UniquenessConstraint in a @MappedSuperclass so that all subclasses carry this constraint. Right now, the following constraint is ignored:
> @MappedSuperclass
> @Table(uniqueConstraints = {@UniqueConstraint(name="inheritedConstraint", columnNames = {"matter", "value"})})
> public class Space { ... }
