Is it possible in hibernate to have an entity where some IDs are assigned and some are generated?
For instance:
Some objects have an ID between 1-10000 that are generated outside of the database; while some entities come in with no ID and need an ID generated by the database.
You could use ‘assigned’ as the Id generation strategy, but you would have to give the entity its id before you saved it to the database. Alternately you could build your own implementation of org.hibernate.id.IdentifierGenerator to provide the Id in the manner you’ve suggested.
I have to agree w/ Cade Roux though, and doing so seems like it be much more difficult than using built in increment, uuid, or other form of id generation.
