JSON Question

415 Unsupported Media Type with Spring 3.2

I'm trying to insert and/or update data into the database using the

PUT
method via JSON using jQuery 1.6, (Jackson 2.1.1 and Spring 3.2.0).

The JS code is as follows.

var itemsArray=[];
var id;

function insertOrUpdate()
{
var i=0;

$('input[name="txtCharge[]"]').each(function()
{
isNaN($(this).val())||$(this).val()==''?itemsArray[i][2]='':itemsArray[i][2]=$(this).val();
i++;
});

$.ajax({
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
datatype:"json",
type: "PUT",
url: "/wagafashion/ajax/InsertZoneCharge.htm",
data: "items=" + JSON.stringify(itemsArray)+"&zoneId="+id+"&t="+new Date().getTime(),
success: function(response)
{
alert(response);
},
error: function(e)
{
alert('Error: ' + e);
}
});
}


The method inside the Spring controller which is mapped with the URL is as follows.

@RequestMapping(value=("ajax/InsertZoneCharge"), method=RequestMethod.PUT, produces=MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody String insertZoneCharge(@RequestBody final MultiValueMap<String, String > data, final HttpServletResponse response, HttpServletRequest request)
{
String message="";
try
{
Map<String, String> params = data.toSingleValueMap();
if(params.get("zoneId")==null||params.get("zoneId").equals("")||params.get("items")==null||params.get("items").equals(""))
{
response.setStatus(HttpServletResponse.SC_BAD_REQUEST);
}
else
{
message=zoneChargeService.insertZoneCharge(params.get("zoneId"), params.get("items"));
}
}
catch (IOException ex)
{
message="An error occured. Data can not be saved.";
Logger.getLogger(ZoneCharge.class.getName()).log(Level.SEVERE, null, ex);
}

return message;
}


The server responds as the question implies,

It works when I remove
@RequestBody final MultiValueMap<String, String > data
, a method parameter and simply use
@PathVariable
to accept request parameters.

Answer

The content type that the browser sends, Content-Type: application/json, does not seem to match @RequestBody final MultiValueMap<String, String > data.

Either:
