PagingAndSortingRepository - custom pageable response structure

Question

Is there a way to simplify the structure returned from this controller:

@GetMapping
public Iterable getAll(@PathParam("page") int page)          


        

Answer 1

Another way is to create a custom page class as you want and create from your data and return

@Data
public class CustomPage {
  List content;
  CustomPageable pageable;

  public CustomPage(Page page) {
    this.content = page.getContent();
    this.pageable = new CustomPageable(page.getPageable().getPageNumber(),
        page.getPageable().getPageSize(), page.getTotalElements());
  }

  @Data
  class CustomPageable {
    int pageNumber;
    int pageSize;
    long totalElements;

    public CustomPageable(int pageNumber, int pageSize, long totalElements) {

      this.pageNumber = pageNumber;
      this.pageSize = pageSize;
      this.totalElements = totalElements;
    }
  }
}

And use like this

@GetMapping
public CustomPage getAll(@PathParam("page") int page) {
    Pageable pageable = PageRequest.of(page, 3);
    return new CustomPage(taskRepository.findAll(pageable));
}

Note: Here @Data of Lombok used for setter getter etc.
