Using hibernate's session.get() with a long ID

Question

I would like to use IDs of type long for my persisted objects. However, I find that get() method requires a Serializable object as its ID parameter (discussed here). What is the best workaround?

Use a Long. Hibernate will do the correct mapping for you. And if you use Java 5, you can

long id = ...;
session.get (id);

and the compiler will do the rest.

Great! This completes my first integration test using hibernate. It took several hours, but I can finally persist and read an entity!

If you are using java 5/6 it should do that for you with autoboxing. However i would recommend using Long instead of long so that it evaluates to null and not zero.
