ajax call MVC Spring Controller, Not Found error

I have a MVC Spring controller. I call this ajax on page load.

$.ajax({
            type:       "get",
            url:        'custom/Service',
            data:       "note1=" + "11",
            dataType:   "json",
            async:   false,
            success:    function() {
                        alert("1");
            },
            error:function (xhr, ajaxOptions, thrownError){
                if(xhr.status == 200 && xhr.statusText == 'parsererror'){
                    window.location.reload();
                } else {
                    alert(xhr.status+","+xhr.statusText);
                    alert(thrownError);
                }
            }    
        });

My controller is:

@RequestMapping("/custom")
public class CustomController {

    @RequestMapping(value="/Service", method=RequestMethod.GET)
        public String Service(
                @RequestParam("note1") String note1,
                HttpServletRequest request, HttpServletResponse response, Locale locale,
                Model model) {
            String result = custom.Service(note1, request, response);
        System.out.println("result: " + result);
        return result;
    }
}

The out put is correct in the console for the controller. But I get "Not Found" error. Here is the developers tool error: GET "MySite/custom/Service?note1=11" 404 (Not Found) . What is wrong?

you need to add response body annotation to your return parameter

 public @ReponseBody String Service(

A spring controller doesn't have to return a view, it can return data, with the reposnsebody annotation. Your original code will look up the result variable as a jsp according to your view resolver settings.

Change your code like below:

@RequestMapping(value="/Service", method=RequestMethod.GET)
        public @ResponseBody String Service(
                @RequestParam("note1") String note1,
                HttpServletRequest request, HttpServletResponse response, Locale locale,
                Model model) {
            String result = custom.Service(note1, request, response);
        return result;
    }

You can access the result in your ajax success function.

success:    function(result) {
                        alert(result);
            },
