How to map all .json URLs to a specific controller

Currently my web.xml shows the following...

<!-- Spring Web MVC dispatcher servlet -->
<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>*.html</url-pattern>
    <url-pattern>*.json</url-pattern>
</servlet-mapping>

What I'd like to do is limit all .json URLs to a specific controller. To be honest I'm not entirely sure how DispatcherServlet in Spring works, so I'm not sure if this is on the right track or not.

The DispatcherServlet follows the request to the right Spring controller. So, depending of your web.xml, you can do this in your web.xml:

<servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

And create a Spring controller, with annotations for instance, like:

@Controller
@RequestMapping(value = "/*.json")
public class TheController {

}
