How to target specific handlers with a @ControllerAdvice @ModelAttribute?

Question

I\'d like to display a warning message on specific pages 5 minutes prior to a system shutdown. Rather than add it manually to each these pages I created a @ControllerAdvice

Answer 1

A controller advice can be limited to certain controllers (not methods) by using one of the values of the @ControllerAdvice annotation, e.g.

@ControllerAdvice(assignableTypes = {MyController1.class, MyController2.class})

If you need to do it on a method level I suggest to take a look at Interceptors.
