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

Support for PostgreSQL UUID data type ------------------------------------- Key: HHH-3579 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3579 Project: Hibernate Core Issue Type: New Feature Components: core Affects Versions: 3.3.1 Reporter: Olivier Van Acker Assignee: Steve Ebersole Fix For: 3.6 Attachments: patch_HH_3579_Hibernate.txt, patch_HH_3579_NullableType.txt, patch_HH_3579_PostgresSQLDialect.txt, patch_HH_3579_TypeFactory.txt, patch_HH_3579_UuidType.txt, postgresuuidType20100613.patch 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
