title: Specify length (size) of @Id @GeneratedValue using Hibernate Annotations
body: <p>Is it possible to specify a starting value and the size of an id that is being auto-generated using Hibernate Annotation <code>@GenerateValue</code>?  For example, instead of just starting at "1", I would like the field to be 8 characters long and fill in with preceeding 0's (00000001, 00000002, 00000003, etc.).</p>
