It is not finding the controllers, this is basic issues. it can be due to following reasons.

A. inside WEB-INF folder you have file web.xml that refers to dispatcherServlet. Here it this case is mvc-config.xml

    dispatcherServlet
    org.springframework.web.servlet.DispatcherServlet
    
        contextConfigLocation
        /WEB-INF/mvc-config.xml

B. This mvc-config.xml file have namespaces and it has to scan the controllers.

C. Check for the correctness of the package name where you have the controllers. It should work.
