@ControllerAdvice is a specialization of the @Component annotation which allows to handle exceptions across the whole application in one global handling component. It can be viewed as an interceptor of exceptions thrown by methods annotated with @RequestMapping and similar.
The @ControllerAdvice annotation was first introduced in Spring 3.2. It allows you to handle exceptions across the whole application, not just to an individual controller. You can think of it as an interceptor of exceptions thrown by methods annotated with @RequestMapping or one of the shortcuts.
