I am just curious.

I make my id setter into private, which is not accessible from other classes.

But still hibernate is able to set the id into new value after the object get persisted.

Any body knows how to do this? i guess it's reflection. but i really have no idea. Any one with any idea?

Thank you

Not sure if hibernate uses this technique, but using reflection you can "break" into the object.

Field m = any_class.getField(xxx);
m.setAccessible(true);

If you do not have a SecurityManager installed which avoids this operation you can access such a field even if it is private.
