@PostConstruct of abstract ancestors are not invoked

Question

I\'m writing a JAX-RS library (not an application).

I have:

abstract class A {

    @PostConstruct
    priva         


        

Answer 1

Annotations are not inherited. You must create a @PostConstruct annotated method for each sub-class.

To assist/remind the developer, you could require a postConstruct() method and hope the developer annotates it appropriately as suggested by its name:

public abstract class A {

    @PostConstruct // annotation here has no value except as a reminder
    public abstract void postConstruct();
