 @GetMapping("/test/page")
    public Result testPage(@PageableDefault(page = 1,size = 5) Pageable page) {
        log.info("test-sort = {}",page.getSort());


        Sort s = page.getSort();
        List list = s.stream().map(order -> {
            Sort.Direction direction = order.getDirection();
            String property = order.getProperty();
            return property + " " + direction;
        }).collect(Collectors.toList());
        return ResultUtil.mapOf("data",page,"sortList",list);
    }

{

  "message": "OK",
  "data": {
    "data": {
      "sort": {
        "empty": false,
        "sorted": true,

      "offset": 50,
      "pageNumber": 1,
      "pageSize": 50,
      "unpaged": false,
      "paged": true

    "sortList": [
      "id ASC"
    ]
  }
}
