I think you can use something like a Spring pageable instance of adding sort to your query page parameters. check this:

    @GetMapping("search")
    public ResponseEntity<List<ProductDTO>> searchProducts(
            @RequestParam(value = "query", required = false, defaultValue = "") String query,
            @Parameter(hidden = true) Pageable pageable,
            HttpServletRequest request) {
        Specification<Product> spec = Specification.where(null); 
        if(!StringUtils.isBlank(query)) {
            Node rootNode = new RSQLParser().parse(query);
            spec = rootNode.accept(new CustomRsqlVisitor<Product>());
        }
        Page<ProductDTO> page = service.searchProducts(spec, pageable);
        HttpHeaders headers = PaginationUtil.generatePaginationHttpHeaders(page, request.getRequestURI());
        headers.setAccessControlExposeHeaders(Arrays.asList(HttpHeaders.LINK, "X-Total-Count"));
        return new ResponseEntity<>(page.getContent(), headers, HttpStatus.OK);
    }
