5.2. Callbacks and listeners inheritance
You can define several entity listeners per entity at different level of the hierarchy.You can also define several callbacks at different level of the hierarchy. But you cannot define two listeners for the same event in the same entity or the same entity listener.
When an event is raised, the listeners are executed in this order:
@EntityListeners for a given entity or superclass in the array order
Entity listeners for the superclasses (highest first)
Entity Listeners for the entity
Callbacks of the superclasses (highest first)
Callbacks of the entity
You can stop the entity listeners inheritance by using the @ExcludeSuperclassListeners, all superclasses @EntityListeners will then be ignored.
