Azuo Lee updated WW-4050:
-------------------------
Description:
If a {{NoSuchMethodException}} is caught when invoking {{getActionMethod()}},
{{AnnotationValidationInterceptor}} should first give any configured
{{UnknownHandler}} a shot, before throwing the exception directly, just as what
{{DefaultActionInvocation.invokeAction()}} does.
Any unknown {{Action}} or unknown {{Result}} is currently handled by
{{Dispatcher.serviceAction()}}, and a *404* error code will be returned as
expected. But an unknown {{Method}} will raise a *500* error, the only way to
avoid this is to configure an {{UnknownHandler}}. Therefore,
{{AnnotationValidationInterceptor}} won't inspect {{UnknownHandler}} at all...
{{GET /foo/list *404* (Action "foo" not found)}}
{{GET /bar/list *200*}}
{{GET /bar/print *500* (Method "print" not found, *404* is expected
instead of *500*)}}
