----------------------------
Summary: AnnotationValidationInterceptor should consult
UnknownHandler before throwing NoSuchMethodException
Key: WW-4050
URL: https://issues.apache.org/jira/browse/WW-4050
Project: Struts 2
Issue Type: Improvement
Affects Versions: 2.3.14
Reporter: Azuo Lee
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 /dog/list 200
GET /dog/print 500 (Method "print" not found, expect 404 instead of 500)
