Solutions

1. Map the property as a binary(16) or varchar(36) column instead of a GUID type.
2. Use a dialect that supports native UUID types (e.g. PostgreSQLDialect).

When it happens

Trigger: Triggered when the application calls a Hibernate dialect feature that the configured database dialect cannot provide: the dialect class does not support GUIDs.

Common situations: Common when running against a database whose dialect lacks this capability, when a mapping or HQL/Criteria query requests unsupported functionality, or when the wrong dialect is configured for the database in use. Error: the dialect class does not support GUIDs.
