Invocation order of Lifecycle Callback Methods

[Moses Marfo]

Below is an example from MZ notes showing the order of invocation of entity lifecycle callback methods.
Can somebody please explain why the method "postPersistAnimal" is invoked last instead of first. I thought it would be called
first since class Pet extends Animal.

thanks

 
@Entity
public class Animal {
....
@PostPersist
protected void postPersistAnimal() {
....
}
}
@Entity
@EntityListeners(PetListener.class)
public class Pet extends Animal {
...
}
@Entity
@EntityListeners({CatListener.class, CatListener2.class})
public class Cat extends Pet {
...
}
public class PetListener {
@PostPersist
protected void postPersistPetListenerMethod(Object pet) {
...
}
}
public class CatListener {
@PostPersist
protected void postPersistCatListenerMethod(Object cat) {
...
}
}
public class CatListener2 {
@PostPersist
protected void postPersistCatListener2Method(Object cat) {
...
}
}
 

CASE 1: If a @PostPersist event occurs on an instance of Cat, the following methods are called
in order:
1 postPersistPetListenerMethod
2 postPersistCatListenerMethod
3 postPersistCatListener2Method
4 postPersistAnimal

Because there are two types of ordering for interceptors, first there is the declaration:
1. Default interceptors(those declared in the orm.xml)
2. Class interceptors
3. Method interceptors

Per declaration type the order is:
1. Super class
2. Own class

Hope this helps
