[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4329) @ForeignKey override of @MappedSuperclass

@ForeignKey override of @MappedSuperclass ----------------------------------------- Key: HHH-4329 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4329 Project: Hibernate Core Issue Type: New Feature Components: annotations Reporter: Christian Bauer Put this @ManyToOne in a @MappedSuperclass: @ManyToOne(fetch = FetchType.LAZY) @JoinColumn(name = "CREATED_BY_USER_ID", nullable = false) // Ideally this foreign key should be ON DELETE SET NULL, however... // Hibernate can't rename these so subclasses would get the same FK constraint name. This doesn't // work, so we need to let Hibernate create a random identifier for these. We could fix this in the // DatabaseObjects.hbm.xml file but we can't even address it because the name is random. This sucks. // So we do a manual SET NULL|DEFAULT when userHome.remove() is called. // @org.hibernate.annotations.ForeignKey(name = "FK_WIKI_NODE_CREATED_BY_USER_ID") protected User createdBy; Now all subclasses get that foreign key constraint name in the database catalog, which isn't possible - constraint names have to be unique.
