Convert JSON array to list of strings in spring using GSON

Question

I have the following JSON

["2848","241"]

By using following jquery code

var list = [];
    $.each($("input[class='selected']:checked"), function(){
        list.push($(this).val());
    });

I am sending this data to my spring controller by using following in ajax post request.

var jsonData = JSON.stringify(list);

My spring controller is as follows

@RequestMapping(value="/myurl", method =  RequestMethod.POST)
    public String sampleMethod(@RequestBody String jsonData){
        Type dataType = new TypeToken<List<String>>(){}.getType();
        List<String> myListObject = gson.fromJson(jsonData, dataType);
        System.out.println(myListObject.size());
        return "redirect:/someotherurl";
    }

I get 500 internal server error for some reason but no stack trace or errors on my console in browser. Please suggest what is missing.?

Answer 1

Fixed it by adding contentType: "application/json" to my ajax request. The server was not interpreting the json data properly.
