        $.ajax({
                url : "submit.htm",
                data: document.getElementById('inputUrl'),
                type: "POST",
                dataType: "text",
                contentType: false, 
                processData: false,

To send an Ajax post request, you could use this :

$.ajax({
     type: "POST",
     url: "submit.htm",
     data: { name: "John", location: "Boston" } // parameters
})

And in Spring MVC the controller: 

@RequestMapping(value = "/submit.htm", method = RequestMethod.POST,produces = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody
String Submit(@RequestParam("name") String name,@RequestParam("location") String location) {
    // your logic here
    return resp;
}
