I am actually following a tutorial to discover Spring framework. I am a beginer with Web technology.
I actually get a problem in my file dispatcher-servlet.xml. I believe that my <context:component-scan base-package="com.tuto.mehdi" /> is not working cause I have an Error 404 when I launch my project :
My console error :
AVERTISSEMENT: No mapping found for HTTP request with URI [/tutoriel-web-spring/] in DispatcherServlet with name 'servlet-dispatcher' avr. 06, 2016 2:26:34 PM org.springframework.web.servlet.PageNotFound noHandlerFound
AVERTISSEMENT: No mapping found for HTTP request with URI [/tutoriel-web-spring/bonjour] in DispatcherServlet with name 'servlet-dispatcher'
That's my code. I believe that I did good but I am not able to identify the problem. Hope you could help me!
