How do I pass an array of integer into spring controller?

Question

script Array of int and I wish to pass into Spring Controller. but I keep getting

400 bad request.

if my js array is

array = [1,2,3,4]
array -> 400 bad request
JSON.Stringify(array) -> I will get [1,2,3,4]

    $.ajax({//jquery ajax
                data:{"images": array},                
                dataType:'json',
                type:"post",
                url:"hellomotto"
                ....
            })

when I loop the string List.. the first element will be '[1'

@RequestMapping(value = "/hellomotto", method = Request.POST)
public void hellomotto(@RequestParam("images") List<String> images){
 sysout(images); -> I will get [1,2,3,4]
}

public void

May I know how can I do this properly? I have tried different combination

The following is a working example:

Javascript:

$('#btn_confirm').click(function (e) {

    e.preventDefault();     // do not submit the form

    // prepare the array
    var data = table.rows('.selected').data();
    var ids = [];
    for(var i = 0; i < data.length; i++) { 
        ids.push(Number(data[i][0]));
    }

    $.ajax({
        type: "POST",
        url: "?confirm",
        data: JSON.stringify(ids),
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(data){
            alert(data);
        },
        failure: function(errMsg) {
            alert(errMsg);
        }
    });
});

Controller:

@RequestMapping(params = "confirm", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE)
public @ResponseBody int confirm(@RequestBody Long[] ids) {
    // code to handle request
    return ids.length;
}
