[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-3579) Support for PostgreSQL UUID data type

]
Steve Ebersole commented on HHH-3579:
-------------------------------------
I just forgot the binding change. That I can accept.
The other, not so much. The intention though is that *your* code can do this:
{code}
Configuration cfg = ...;
cfg.registerTypeOverride(
/*
* Create a new PostgresUUIDType instance in order to register it as the default
mapping for java.util.UUID.
*
* The other option is to manually specify to use this type for all UUID fields.
*/
new org.hibernate.type.PostgresUUIDType() {
protected boolean registerUnderJavaType() {
return true;
}
}
);
{code}
Support for PostgreSQL UUID data type

Time Spent: 6.45h
Remaining Estimate: 0h
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
