Hi,

I'd like to use a custom type for an id field, that's represented as an INTEGER in the database.

I can't seem to get Hibernate to cope with this, as it's expecting either an Integer, Long, String, etc. in the case of auto-generated id assignment.

Is there a way I can do this without having to write a setID(Integer id) { this.id = new MyIDClass(id); }
method?

My custom type is basically just a wrapper around an Integer, and it has the appropriate custom type defined and used for Hibernate.
It extends org.hibernate.type.IntegerType, but if I override the public Class getReturnedClass() method to return say MyIDClass.class, it throws the error that says it was expecting an integer, long, string, etc....
But if I return Integer.class from that method, it goes fine until it expects a setter like setID(Integer id).
So is there a way to tell Hibernate to work with custom id types for auto-generated values, and can someone explain how?

Thanks,
David

I guess you have to implement your own id generator since the built-in generators in Hibernate only support the types that you mention.

Yeah well I've been browsing through the source and submitted something sort of a bug report / feature enhancement request because custom types for auto-generated ids could be implemented -- in my belief -- in about 10 lines of added code. Creating a custom id generator just for this seems overhead, when it could be accomplished with just a few lines elsewhere.

But if someone knows of something that I'm missing here, please let me know.
