Your jsp should be called "home.jsp" instead of "index.jsp"
your package name in scan is
<context:component-scan
base-package="com.emenpy.spring.web.controllers">
</context:component-scan>
when it should be as your directory tree shows
<context:component-scan
base-package="com.cuong.spring.web.controllers">
</context:component-scan>
as the scaning didn't find your controller the mapping wasn't done
