ajax post提交多个参数后台controller @RequestParam方式接收

<script >
    function goRead( id, cartoonId){
        alert("id="+id+"  cartoonId="+cartoonId)
        var params = {
            "page":0,
            "size":3,
            "cartonDetailNum":id,
            "cartoonId":cartoonId
        }
        $.ajax({
                type: "post",
                url: "/chapterImage/findPage",
                data: params,
                // data: {"page":"0","size":"3","cartonDetailNum":id,"cartoonId":cartoonId},//或者这样写进去
                dataType: 'json',
                success: function (r) {
                    alert("请求成功"+r);
                    window.location.reload();

                },
            error:function(result) {
                alert("error");
            }
            })
    } ;
   </script>

@RequestMapping(value = “/findPage”,method = RequestMethod.POST)
public String doFindPageByPageNum(@RequestParam(value = “page”) String page, @RequestParam String size,@RequestParam String cartonDetailNum,String cartoonId){
//代码省略
}
