How do I add multiple Spring MVC controllers to my maven project - spring-mvc

Question

I need to add multiple controllers to my Spring MVC project which only has one right now. My current project only has one SpringDispatcher in the web.xml and it maps the
/
to the '/' of the controllers
#RequestMapping(value = "/")
start-up controller. Because everything is in the one web.xml and there are no other xml files that do any dispatcher mapping, should I not be able to just add a new
/
with a different controller pattern to the web.xml? Below are the web.xml and the one working controller.
web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

First of all, this mapping should only work for the application root. If you want any path under the application root then use
/*
Now, in your case spring dispatcher will only be called if you open your browser to point to web application root without specifying any path which as i might guess is not what you want. So, use /* to forward all requests to the spring dispatcher and the use any request mapping in your controllers
