Best way to fetch a BLOB LAZY using Hibernate

Or implementing FieldHandled
Use "fake" one-to-one mappings instead of properties. Remove the LOB fields from your existig class, create new classes referring to the same table, same primary key, and only the necessary LOB fields as properties. Specify the mappings as one-to-one, fetch="select", lazy="true". So long as your parent object is still in your session, you should get exactly what you want.
