尝试将数据从js发布到spring boot controller

我正试图从这个js发布我的数据

$.ajax({
        type: 'POST',
        url: '/url',
        data: {
            arr: tdValues
        },
        success: function () {
            location.reload();
        }
    });

控制器中的所有代码都可以正常工作，来自js的数据不是空的

@PostMapping("/url")
 public ModelAndView deleteQuestions(@RequestParam(value = "arr[]") String[] tdValues) {
 ModelAndView modelAndView = new ModelAndView();
 modelAndView.setViewName("page");
 return modelAndView;
}

但在那之后，我得到了例外

Required String[] parameter 'arr[]' is not present

有任何建议如何解决？
