[JIRA] (HHH-15510) JoinColumn annotation not recognized when entity is mapped via XML file

by Mike Becker (JIRA)

Mike Becker ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=6321cb8... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiYTM2NzE4YTM4... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15510?atlOrigin=eyJpIjoiYTM2Nz... ) HHH-15510 ( https://hibernate.atlassian.net/browse/HHH-15510?atlOrigin=eyJpIjoiYTM2Nz... ) JoinColumn annotation not recognized when entity is mapped via XML file ( https://hibernate.atlassian.net/browse/HHH-15510?atlOrigin=eyJpIjoiYTM2Nz... ) Change By: Mike Becker ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=6321cb8... ) If an entity is mapped via an XML file, an ElementCollection cannot be annotated with OnDelete because hibernate complains that JoinColumn is missing. But JoinColumn is actually there. The error message is {quote}Unidirectional one-to-many associations annotated with @OnDelete must define @JoinColumn{quote} The following test case demonstrates this behavior. Change the TRIGGER_BUG flag to observe how the test case is working when not using the XML file and how the bug occurs when using the XML file.

[JIRA] (HHH-15509) Avoid entity loading on delete() when possible

by Yoann Rodière (JIRA)

Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiZmE5MDhjZGJm... ) / Improvement ( https://hibernate.atlassian.net/browse/HHH-15509?atlOrigin=eyJpIjoiZmE5MD... ) HHH-15509 ( https://hibernate.atlassian.net/browse/HHH-15509?atlOrigin=eyJpIjoiZmE5MD... ) Avoid entity loading on delete() when possible ( https://hibernate.atlassian.net/browse/HHH-15509?atlOrigin=eyJpIjoiZmE5MD... ) Issue Type: Improvement Assignee: Unassigned Components: hibernate-core Created: 14/Sep/2022 04:17 AM Fix Versions: 6.2.0 Priority: Major Reporter: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) In some very specific cases (no lifecycle callbacks, no cascades, …), deleting an entity could only involve running a few DB statements along the lines of delete from table where id = ?. In those cases, loading the entity would (in theory) not be necessary. In those very specific cases, when EntityManager.delete(Object) gets passed an uninitialized entity proxy, it would be a nice optimization if Hibernate ORM could skip initializing the proxy and just run the delete statements. This would remove at least one DB lookup for users doing a “delete-by-id” such as session.delete(session.getReference(MyEntity.class, 42L)) in some situations, while still doing the right thing (cascades, calling listeners, …) when the optimization is not possible. Note I’m not sure this is possible, but it’s probably worth investigating, be it only to document why it’s not possible.
