konfigurieren web.xml für den Frühling

Ich bin neu in spring-Framework und habe Probleme mit Verbindung/konfigurieren springframework durch web.xml.
Ich erhalte folgende Fehlermeldung beim ausführen meiner app.

Fehler:

Offensichtlich, es konnte nicht finden, Klasse org.springframework.web.- servlet.DispatcherServlet in den Bibliotheken. Allerdings, ich weiß nicht, wie zu sagen, web.xml wo kann man für diese Klasse.

web.xml
