IterableMapping with additional shared value

[Baptiste Pernet]

Hello, I wanted to run this problem by the community to see what's the best way of doing this.

Here is what I have done so far.

interface SellerMapper {

  @Mapping(target = "sellers", source = "sellers")

  ProductDto toProductDto(Product product);

  default List<SellerDto> toSellerDtos(Product product) {

    if (product == null || product.getSellers() == null) {

      return null;

    }

    List<SellerDto> sellers = toSellerDtos(product.getSellers());

    sellers.forEach(seller -> seller.setProductId(product.getId()));

    return sellers

  }

  @IterableMapping

  List<SellerDto> toSellerDtos(List<Seller> sellers);

  @Mapping(target = "id", source = "id")

  @Mapping(target = "productId", ignore = true)

  SellerDto toSellerDto(Seller seller);

}

I don't really like the method List<SellerDto> toSellerDtos(Product product)

and I would like to see how I could do that differently. I tried with an @AfterMapping but with no success.

Warm Regards
