How do I extract client data from the httpheaders?

Question

I have a login post request.

@RequestMapping(value = EWPRestContants.DO_LOGIN, method = RequestMethod.POST, consumes=MediaType.APPLICATION_XML_VALUE,produces=MediaType.TEXT_PLAIN_VALUE)
public ResponseEntity<String> doLogin(@RequestBody Loginrequest logReq,@RequestHeader HttpHeaders headers, HttpServletRequest request, HttpServletResponse httpResponse) throws Exception {
   //........
     }

I want to extract data from the header. Is there an API to do so?

Suppose my header contains customer msIsdn number and name. How do I fetch those details. getFirst() is used to get the user-agent details or the start line only.

This is the answer. String id= headers.getFirst("ID");

like

@RequestHeader(value="User-Agent", defaultValue="foo") String userAgent

@RequestMapping(value = EWPRestContants.DO_LOGIN, method = RequestMethod.POST, consumes=MediaType.APPLICATION_XML_VALUE,produces=MediaType.TEXT_PLAIN_VALUE)
public ResponseEntity<String> doLogin(@RequestBody Loginrequest logReq,@RequestHeader(value="User-Agent", defaultValue="foo") String userAgent,@RequestHeader(value="Accept-Language") String acceptLanguage, HttpServletRequest request, HttpServletResponse httpResponse) throws Exception {
   //........
     }

or from

    @RequestMapping(value = EWPRestContants.DO_LOGIN, method = RequestMethod.POST, consumes=MediaType.APPLICATION_XML_VALUE,produces=MediaType.TEXT_PLAIN_VALUE)
    public ResponseEntity<String> doLogin(@RequestBody Loginrequest logReq,@RequestHeader HttpHeaders headers, HttpServletRequest request, HttpServletResponse httpResponse) throws Exception {
String userAgent = headers.getFirst(HttpHeaders.USER_AGENT);
         }

From the second solution USER_AGENT cannot be resolved or is not a field I get the following error.
