Native support for UUID, even if the underlying persistence layer doesn't support a UUID data type.
---------------------------------------------------------------------------------------------------

                 Key: HHH-5387
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5387
             Project: Hibernate Core
          Issue Type: New Feature
            Reporter: Bill DeCoste




 

-          We worked around this issue by treating UUIDs as a string at the member level, then overrode the getter/setter functions to convert from string to UUID and vice-versa.  This approach works, but is inefficient and suboptimal.  It also prevented us from doing a proper PKClass override in a derived entity class (because UUID is hacked to be a String at the member level, and a UUID type at the property getter/setter level).

 

-          Besides native support for UUID built into Hibernate for all supported persistence dialects, it'd be nice to be able to specify custom object serializers/deserializers.

 

-          Support for methods 1, 2 and 5 of UUID would be great (since the standard Java implementation lacks this ability).  On method 2, allow the specification of domain and UID components.
