Spring MVC Framework provides following mechanisms to help us

achieve exception handling:

Controller Based: A developer can define exception handler

methods in a Controller class. To do so, they have to annotate the

methods with @ExceptionHandler annotation.

Global Exception Handler: Spring provides @ControllerAdvice

annotation for exception handling as cross-cutting concern. We can

mark any class as global exception handler by using this annotation.

HandlerExceptionResolver implementation: Spring Framework

provides HandlerExceptionResolver interface that can be

implemented to create a global exception handler.
