public class DSpacePostgreSQL82Dialect
extends org.hibernate.dialect.PostgreSQL82Dialect

UUID's are not supported by default in hibernate due to differences in the database in order to fix this a custom sql dialect is needed. Source: https://forum.hibernate.org/viewtopic.php?f=1&t=1014157

contributeTypes

public void contributeTypes(org.hibernate.metamodel.spi.TypeContributions typeContributions,
                            org.hibernate.service.ServiceRegistry serviceRegistry)

Overrides:

contributeTypes in class org.hibernate.dialect.Dialect

registerHibernateType

protected void registerHibernateType(int code,
                                     String name)

Overrides:

Parameters:

sqlCode - JDBC type-code for the column mapped by this type.

Returns:

Descriptor for the SQL/JDBC side of a value mapping.
