[Spring] Ajax에서 배열보내서 Controllor로 받기

// Javascript
var lastName = [];
var kim = document.getElementsByClassName("kim");
var lee = document.getElementsByClassName("lee");
var park = document.getElementsByClassName("park");

for(var i = 0; i < kim.length; i++) {
    var data = {
        kim : kim[i].value,
        lee : lee[i].value,
        park : park[i].value,
    }

    lastName.push(data);
}

$.ajax({
    url: "/selectLastName",
    type: "POST",
    data:{lastName:JSON.stringify(lastName)},
    success: function(result){
    },
});

 

// Controllor
@PostMapping("/selectLastName")
@ResponseBody

    String lastName = request.getParameter("lastName");
    JSONParser jp = new JSONParser(); 
    JSONArray ja = (JSONArray)jp.parse(lastName);
