How to pass values from jquery to a Spring Controller and return a List? – Jquery ajax

I am working on a simple project where I need to pass some form parameters like database name and a query to the Spring Controller. The Controller passes the query to the corresponding service class(corresponding to the dbname) and return the resultset as a java.util.List.
I am using Jquery/ajax to pass the values to the Controller but the values are not reaching till the Controller.
Below is my code.

JQuery/ajax

'''
    function ajaxAsyncRequest()
    {
    //Creating a new XMLHttpRequest object
    var xmlhttp;
    var dbname = document.getElementById("dbradio").value;
    var query = document.getElementById("myTextBox").value;
    alert(dbname)
    alert(query)

    $.ajax({
        type: "GET",
        url: "/getResult",
        data: "dbradio="+dbname+"&myTextBox="+query,

        success: function(response)
        {
            $('#resultList').html(response);
        },
        error: function(e)
        {
            alert('Error: ' + e);
        }
      });

    }

'''

JSP:

'''


    <form action="" target="result">

      <input type="radio" id="dbradio" value="mysql"> MySQL
      <input type="radio" id="dbradio" value="redshift"> RedShift

      <textarea id="myTextBox" cols="50" rows="10" style="background-color:#FCF5D8;color:#AD8C08;"> 
      </textarea>


       <p><input type="submit" value="Submit" onclick='ajaxAsyncRequest()'/></p>
       </form>

'''

Controller

'''



        @RequestMapping(value="/getResult", params = { "dbradio", "myTextBox" }, method = 
             RequestMethod.GET)

        public List<Map<String,Object>> getResult(@RequestParam("dbradio") String dbname, 
         @RequestParam("myTextBox") String query, HttpServletRequest req, HttpServletResponse res) {

        System.out.println("In Controller");
        System.out.println(dbname);
        System.out.println(query);
        List<Map<String,Object>> queryResult = service.getQureyResults(query);

        ModelAndView mv= new ModelAndView();
        mv.setViewName("index");    
        mv.addObject("result", queryResult);
        return queryResult;
          }
