Hello all -
I have a one-to-many association between roles and users. I have created/tested the ORM mappings using Hibernate and successfully persisted instances of both classes. Below are simplified definitions of the classes:
When I create a
junit test and attempt to invoke contains() on the user collection the assertion returns true as expected. Below I have a snippet of code to illustrate:
However, when I run another unit test that persists both the user and the role using Hibernate, the assertion fails.
[CODE]
/**
* JUnit Test. The first assertion passed the 2nd assertion fails.
*/
public void testRoleContainsPersist(){
Transaction tx = HibernateSessionFactory.currentSession().beginTransaction();
Role sysadmin = new Role("sysadmin");
User smith = new User("jsmith123","John","Smith");
sysadmin.addUser(smith);
assertTrue(sysadmin.contains(smith)); // returns true
rdao.makePersistent(sysadmin);
tx.commit();
assertTrue(sysadmin.contains(alcazar)); // returns false
}
/CODE]
Hibernate stresses the importance of overriding the equals() and hashCode() methods using business equality (which is what I've done). However, after I persist these objects, I cannot invoke contains() successfully.
I suspect it is my implementation of equals() and/or hashCode(), however, I do not know why. I'm quite frustrated trying to find a solution to this and was hoping you can point me in the right direction. Any feedback is appreciated.
Thanks!
