Based on the answer for problem with x-www-form-urlencoded with Spring @Controller

I have written the below @Controller method

@RequestMapping(value = "/{email}/authenticate", method = RequestMethod.POST
            , produces = {"application/json", "application/xml"}
            ,  consumes = {"application/x-www-form-urlencoded"}
    )
     public
        @ResponseBody
        Representation authenticate(@PathVariable("email") String anEmailAddress,
                                    @RequestBody MultiValueMap paramMap)
                throws Exception {


            if(paramMap == null || paramMap.get("password") == null) {
                throw new IllegalArgumentException("Password not provided");
            }
    }

the request to which fails with the below error

{
  "timestamp": 1447911866786,
  "status": 415,
  "error": "Unsupported Media Type",
  "exception": "org.springframework.web.HttpMediaTypeNotSupportedException",
  "message": "Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported",
  "path": "/users/usermail%40gmail.com/authenticate"
}

[PS: Jersey was far more friendly, but couldn't use it now given the practical restrictions here]

The problem is that when we use application/x-www-form-urlencoded, Spring doesn't understand it as a RequestBody. So, if we want to use this we must remove the @RequestBody annotation.

Then try the following:

@RequestMapping(value = "/{email}/authenticate", method = RequestMethod.POST,
        consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE, 
        produces = {MediaType.APPLICATION_ATOM_XML_VALUE, MediaType.APPLICATION_JSON_VALUE})
public @ResponseBody  Representation authenticate(@PathVariable("email") String anEmailAddress, MultiValueMap paramMap) throws Exception {
   if(paramMap == null && paramMap.get("password") == null) {
        throw new IllegalArgumentException("Password not provided");
    }
    return null;
}

Note that removed the annotation @RequestBody
