Erreur 404 "org.springframework.web.servlet.DispatcherServlet noHandlerFound"
Bonjour,
je débute avec spring et je souhaiterai créer un form mais je suis confronté à une erreur quand je tente d'accéder à l'adresse http://localhost:8080/starterSpring/user/createUser.jsp :roll:
ATTENTION: No mapping found for HTTP request with URI [/starterSpring/user/createUser.jsp] in DispatcherServlet with name 'CreationUser'
Voici mon web.xml:

J'ai également une autre question, j'ai vu dans certains tuto que des personnes utilisaient l'héritage de SimpleFormController pour leurs controller et override des méthodes comme referenceData. Quelle est la meilleure solution?
Merci bien pour votre aide que je puisse avancer et m'appuier sur un exemple qui fonctionne
