Add HandlerMethod as possible parameter to @ExceptionHandler method [SPR-10047]

[spring-projects-issues]

Pavel Orehov opened SPR-10047 and commented

Currently the @ExceptionHandler method can not contain HandlerMethod as method parameter as it is not passed by spring framework.
It could be very helpful for investigating throwing exception method, for example, for custom annotations.
The workaround that I found is to create mvc interceptor and pass the MethodHandler via ServletRequest.attributtes.

The following is the suggested API, handler is a new possible parameter:

@ExceptionHandler(Exception.class)
public ResponseEntity<Object> handleException(Exception ex, WebRequest request, HandlerMethod handler)
{ ... }

This should be implemented since 4.x, from the documentation:

HandlerMethod as a method argument on @ExceptionHandler methods, especially handy in @ControllerAdvice components.

So maybe the bug can be closed?
