    After intoducing globalHandler exception , any place exception happens, Global class will be called from there?

    • @javajungle
      @javajungle 2 місяці тому

      exactly @ControllerAdvice is taking care that is why we should annotate global exception handling class with this annotation, @ControllerAdvice is a specialized version of the @Component annotation that allows you to handle exceptions globally, apply model attributes to multiple controllers, and bind methods for multiple controllers in a single place.
