How to get the JSON reponse in drop zone ajax call

Question

Currently working on a dropzone functionality with the spring MVC framework.

This is the method in the controller class ( I'm using internal view resolver)

 @RequestMapping(value = "/save", method = RequestMethod.POST, produces = "application/json")
        @ResponseBody
        public String save(MultipartHttpServletRequest request,
                HttpServletResponse response, Model map) {
//The logic for adding file to db and creation of json object here
.....
.....

userDataJSON = strWriter.toString();
return userDataJSON;

}

Here is my javascript for the dropzone upload

Dropzone.options.myAwesomeDropzone = {          

        maxFilesize : 2,
        addRemoveLinks : true,          
        uploadMultiple : true,          
        init : function() {     
            this.on("addedfile", function(file) {                               
                $.ajax({
                method  : 'get'             
                }).done(function( data, textStatus, xhr ) {                 
                    alert(data);
                    //Expecting the json objec here

                });
            });  
        }
};

Here i'm not getting the json reponse, from the controller.

Please let me know if you have any solutions for me. Thanks in advance.

I believe by default, dropzonejs is doing the ajax request to your file.

    $("#uploader").dropzone({ 
        url: "/upload.php",
        maxFilesize: 3,
        init: function() {
            this.on("success", function(file, response) {
                var obj = jQuery.parseJSON(response)
                console.log(obj);
            })
        }
    });

the url param is what is getting hit via the ajax call, and response (in the console.log) is what is coming back from /upload.php
