前端传实体数组;后台list实体接收参数

前端页面:

 $.ajax({
            url: url,
            data: JSON.stringify(data),
            dataType: "json",
            contentType: "application/json",
            type: "POST",
            success: function (data) {
                if(data.returnCode == "000000"){
                    alert("配置成功！");
                    esst.popups_close(obj);
                }else{
                    alert("配置失败！");
                }
            }
        });

后台接收:

    @RequestMapping(value = "update",method = RequestMethod.POST)
    @ResponseBody
    public ReturnBean<?> update(@RequestBody List<Entity> list, HttpServletRequest request, HttpServletResponse response) {

    }
