24.1.29. @GeneratedValue

<div class="paragraph">

The [`@GeneratedValue`](http://docs.oracle.com/javaee/7/api/javax/persistence/GeneratedValue.html) annotation specifies that the entity identifier value is automatically generated using an identity column, a database sequence, or a table generator.
Hibernate supports the `@GeneratedValue` mapping even for `UUID` identifiers.
