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);
}
