Use this method if you dont want to make a class you can directly send JSON without Stringifying. Use Default Content Type. Just Use @RequestParam instead of @RequestBody. @RequestParam Name must be same as in json.

Ajax Call

function searchText() {
    var search = {
    "pName" : "bhanu",
    "lName" :"prasad"
    }
    $.ajax({
    type: "POST",
    /*contentType : 'application/json; charset=utf-8',*/ //use Default contentType
    dataType : 'json',
    url: "/gDirecotry/ajax/searchUserProfiles.htm",
    data: search, // Note it is important without stringifying
    success :function(result) {
    // do what ever you want with data
    }
    });

Spring Controller

RequestMapping(value="/gDirecotry/ajax/searchUserProfiles.htm",method=RequestMethod.POST)

   public  @ResponseBody String  getSearchUserProfiles(@RequestParam String pName, @RequestParam String lName) {
       String pNameParameter = pName;
       String lNameParameter = lName;

       // your logic next
   }
