]
David Driscoll commented on HHH-3579:
-------------------------------------
I successfully ran thru some tests with just 2 changes:
set registerUnderJavaType to true, and needed to use a different setObject overload in
method: getBinder().
I will attach a small patch file.
Support for PostgreSQL UUID data type

PostgreSQL has since version 8.3 UUID as data type nativly supported in the database.
The only way to get this to work in Hibernate is to add <column name="id"
sql-type="uuid"/> to your mappings file (or @columnDefinition via
annotations)
and create your own custom usertype (e.g. public class UUIDUserType implements UserType,
Serializable {..} ) and map this to java.util.UUID
worth mentioning is that java.util.UUID is only introduced in java 1.5 so there might be
a backwards compatibility problem
