When a mapped superclass gets enhanced before a subclassing entity, the entity does not get enhanced itself. An entity does get enhanced if it comes before the mapped superclass.
Find attached a sample project that reproduces this behaviour. Both AEntity and CEntity subclass BSuperclass. AEntity gets enhanced, CEntity does not.
Run with mvn test produces:
{noformat}
[INFO] Successfully enhanced class [eu.pinske.model.CEntity]
{noformat}
But the check fails:
{code:java}
Assert.assertTrue("A not enhanced", ManagedEntity.class.isAssignableFrom(AEntity.class));
{code}
{noformat}
test(eu.pinske.test.EnhanceTest) Time elapsed: 0.056 sec <<< FAILURE!
java.lang.AssertionError: C not enhanced
{noformat}
I guess this is due to this check in org.hibernate.bytecode.enhance.spi.Enhancer
{code:java}
if ( PersistentAttributesHelper.isAssignable( managedCtClass, Managed.class.getName() ) ) {
log.debugf( "Skipping enhancement of [%s]: already enhanced", managedCtClass.getName() );
return;
}
{code}
After the mapped superclass has itself been enhanced (it then implements Managed), the entity does also already implement that, despite not having been enhanced itself. |
