    copied!<p>This is something that I think should be very easy, but so far I have not been able to get it to work.</p> <p>What I want to do is map my root path to a Spring MVC Controller. With a normal <code>Servlet</code>, I would just add a mapping for "<code>/</code>" in my <code>web.xml</code>, and it would pick it up quite well. But with Spring MVC, not so much.</p> <p>I have tried many combinations, but none seem to work. I think the following one should work.</p> <p>In <code>web.xml</code>:</p> <pre><code>&lt;servlet-mapping&gt; &lt;servlet-name&gt;myDispatcherServlet&lt;/servlet-name&gt; &lt;url-pattern&gt;/&lt;/url-pattern&gt; &lt;/servlet-mapping&gt; </code></pre> <p>In my <code>contextConfigLocation</code> file:</p> <pre><code>&lt;bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"&gt; &lt;property name="alwaysUseFullPath" value="true"/&gt; &lt;property name="mappings"&gt; &lt;util:map&gt; &lt;entry key="/" value-ref="rootController"/&gt; &lt;/util:map&gt; &lt;/property&gt; &lt;/bean&gt; &lt;bean id="rootController" class="my.package.RootController"&gt; </code></pre> <p>Then obviously, there is the case of the controller itself. I have no clue how to map the method to the actual root path. My attempt is something like this:</p> <pre><code>public class RootController extends MultiActionController { @RequestMapping("/") public ModelAndView display(HttpServletRequest request, HttpServletResponse response) throws Exception { final Map&lt;String, Object&gt; model = new HashMap&lt;String, Object&gt;(); model.put("someVariable", "Hello, MVC world."); return new ModelAndView("rootPage", model); } } </code></pre> <p>So let's say my application runs on <code>http://localhost:8080/app/</code>, I want that exact URL to execute the method <code>display</code>. I do not want to type anything after <code>/app/</code>. In fact, some things after <code>/app/</code> are mapped to other controllers, and that all works fine (and they have to keep working).</p> <p>What am I missing here? Why is this not simply working? If I use the same <code>url-pattern</code> to map to a plain <code>Servlet</code> instance, it works fine and I reach the <code>doGet</code> method, but with Spring MVC I seem to missing some particular black magic to get this to work.</p>
