Question

I want to have the same request mapping but resolve to different view depending on the file extension. I have two JSPs one that renders HTML and another that renders XML. Depending on the file extension I should resolve to the corresponding jsp.

This is my controller:

@Controller
public class FileManagementController {

    @RequestMapping(value="/filemanagements", method=RequestMethod.GET)
    public ModelAndView list() {
        //if file extension .xml return  /filemanagement/listXml
        //if no file extension present return /filemanagement/list
    }

}

And I Have the following y Root of my WebApp:

/jsp/filemanagement/list.jsp

<%@page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%>

..

/jsp/filemanagement/listXml.jsp

<?xml version="1.0" encoding="UTF-8"?>
<%@page contentType="text/xml" pageEncoding="UTF-8"%>

….

This is how I have configured my ViewResolver in the servletContext.xml:

<bean id="viewResolver"
      class="org.springframework.web.servlet.view.InternalResourceViewResolver">
      <property name="prefix" value="/WEB-INF/jsp/" />
      <property name="suffix" value=".jsp" />
</bean>

Have a look at ContentNegotiatingViewResolver. From the javadoc:

This view resolver uses the requested media type to select a suitable View for a request.

If the requested path has a file extension and if the setFavorPathExtension(boolean) property is true, the mediaTypes property is inspected for a matching media type.

There is also a section of the ref manual covering this resolver.
