hi all ,


I have a query.. Its written in hibernate's document that hibernate can access even private & protected methods. It goes as --- " we usually don't manipulate the identity of an object, hence the setter method should be private. Only Hibernate will assign identifiers when an object is saved. You can see that Hibernate can access public, private, and protected accessor methods, as well as (public, private, protected) fields directly."

In plain java, we can't access the private methods outside the defined class. Then how is it that hibernate is able to access any of the accessor methods.

Hibernate uses CGLib to create proxy classes that extend your class. These proxy classes are created in the same package, and exploit all sorts of neat features of reflection and byte-code hackery. Don't try it at home, folks.

Hi!

When using reflection, you can actually modify the accessibility of a class element (field or method) [see http://java.sun.com/j2se/1.4.2/docs/api/java/lang/reflect/AccessibleObject.html#setAccessible(boolean)].

As it has been set; there are very rare legitimate use cases for this!

All the best,

René
