Contrary to what the ExceptionHandler#value()
attribute indicates
Class<? extends Throwable>[] value() default {};
and @ExceptionHandler
is only meant to handle Exception
and its sub types.
Spring uses ExceptionHandlerExceptionResolver
to resolve your annotated handlers, using the following method
doResolveHandlerMethodException(HttpServletRequest request,
HttpServletResponse response, HandlerMethod handlerMethod, Exception exception)
which as you can see only accepts an Exception
.
You cannot handle Throwable
or Error
types with @ExceptionHandler
with this configuration.
I would tell you to provide your own HandlerExceptionResolver
implementation which does handle Throwable
instances, but you’d need to provide your own DispatcherServlet
(and most of the MVC stack) yourself since DispatcherServlet
does not catch
Throwable
instances at any place where you could make any significant difference.
Update:
Since 4.3, Spring MVC wraps a thrown Throwable
value in a NestedServletException
instance and exposes that to the ExceptionHandlerExceptionResolver
.
