Можно ли реализовать пользовательскую страницу ошибки HTTP 404 на основе аннотаций с помощью Spring 3.2.1? Я искал способы на различных форумах, но не нашел четкого ответа.
Я также пытался настроить с помощью web.xml, но он не работает, когда я обращаюсь к несопоставленному URL-адресу. Любая помощь, пожалуйста?
