Question

If you have a parent class which uses the @PostConstruct annotation and you create a child class that derives from it. Will the @PostConstruct method be called automatically each time an instance of the child class is created? since that @PostConstruct method is called each time an instance of the the parent is created.

I Know that in the child class it calls super(); for us automatically without us having to call it.

im just not sure if the @PostConstruct annotation is automatically called if that child class calls the super(); constructor.

Answer 1

After testing this scenario, the @PostConstruct method in the base class WILL automatically be called.

The flow goes like this:

1. When the child class is created, you are in the constructor of the child class, you then are forced into the parent class automatically.
2. Once the parent class constructor is done you are sent back to the child class’ constructor.
3. Once the child class constructor is done you are automatically sent to the PARENT classes @PostConstruct method
