set content type for xml response in spring

I have this method that returns an object which is then serialized.

I'd like to set the content type of the response (e.g. as application/xml).

How can I do this?

I have found other posts but they are not very clear about how to do this for xml type

@RequestMapping(value = "/Disco/GetAreasAtLevel", method = RequestMethod.GET)
@ResponseBody
public GetAreasAtLevelResponseElement getAreasAtLevel(@RequestParam("AreaId") String areaId) {
        GetAreasAtLevelResponseElement root = new GetAreasAtLevelResponseElement();
        root.setArea("TEST");
        return root;
    }

This is my spring-ws-servlet.xml file

A simple option is to set the produces attribute of the @RequestMapping annotation to MediaType.APPLICATION_XML_VALUE (or "application/xml"), e.g.

@RequestMapping(produces = MediaType.APPLICATION_XML_VALUE, 
    value = "/Disco/GetAreasAtLevel", 
    method = RequestMethod.GET)
@ResponseBody
public GetAreasAtLevelResponseElement getAreasAtLevel(
    // ...
}

and at the same time specifying the @EnableWebMvc or <mvc:annotation-driven />.

These feature are available as of Spring 3.1.

@RequestMapping(value = "/Disco/GetAreasAtLevel", method = RequestMethod.GET)
@ResponseBody
public void getAreasAtLevel(@RequestParam("AreaId") String areaId, HttpServletResponse response) {
    GetAreasAtLevelResponseElement root = new GetAreasAtLevelResponseElement();
    root.setArea("TEST");
    PrintWriter pr = response.getWriter();
    response.setContentType("application/xml");
    //parse your data to XML
    String xml = parseXml(root);
    pr.write(xml);
    // rest of the code.
    //
}
