MapStrut maping not working with class using lombok - spring

Question

I'm modifiying the maping on existing software. It uses MapStruct (1.2.0), and Lombok (1.16.18)
Before modification, i have this class:
public class ReservationCreateRSRDTO {
#JsonProperty("reservation_id")
private String reservationId;
}
I need to change it to
#Data
#GenerateCoverage
#NoArgsConstructor
#AllArgsConstructor
#Builder
#JsonInclude(JsonInclude.Include.NON_NULL)
public class ReservationCreateRSRDTO {
#JsonProperty("delivery_slot_reservation")
private DeliverySlotReservation deliverySlotReservation;
}
#Data
#GenerateCoverage
#NoArgsConstructor
#AllArgsConstructor
#Builder
public class DeliverySlotReservation {
#NotBlank
#JsonProperty("identifier")
#Size(min = 13, max = 13)
private String identifier;
}
which is mapped by
#Mapper
public interface ReservationControllerMapper {
ReservationCreateRSRDTO toReservationCreateRSRDTO(ReservationCreateODTO reservationCreateODTO);
}
The source object:
#Data
#GenerateCoverage
#NoArgsConstructor
#AllArgsConstructor
#Builder
public class ReservationCreateODTO {
private String reservationId;
}
I modified the mapping to
#Mappings({
#Mapping(source = "reservationId", target = "deliverySlotReservation.identifier"),
})
ReservationCreateRSRDTO toReservationCreateRSRDTO(ReservationCreateODTO reservationCreateODTO);
But when accesing attribute deliverySlotReservation from ReservationCreateRSRDTO after the mapping, it returns null.
I'm triying to debug in eclipse, into generated classes:
#Override
public ReservationCreateRSRDTO toReservationCreateRSRDTO(ReservationCreateODTO reservationCreateODTO) {
if ( reservationCreateODTO == null ) {
return null;
}
ReservationCreateRSRDTO reservationCreateRSRDTO = new ReservationCreateRSRDTO();
reservationCreateRSRDTO.setDeliverySlotReservation(
reservationCreateODTOToDeliverySlotReservation( reservationCreateODTO ) );
return reservationCreateRSRDTO;
}
protected DeliverySlotReservation reservationCreateODTOToDeliverySlotReservation(ReservationCreateODTO reservationCreateODTO) {
if ( reservationCreateODTO == null ) {
return null;
}
DeliverySlotReservation deliverySlotReservation = new DeliverySlotReservation();
deliverySlotReservation.setIdentifier( reservationCreateODTO.getReservationId() );
return deliverySlotReservation;
}
I call toReservationCreateRSRDTO with a not null ReservationCreateODTO with not noll identifier
but debbuger is not stepping into reservationCreateODTOToDeliverySlotReservation().
No exception es thrown, but toReservationCreateRSRDTO() returns an ReservationCreateRSRDTO object with null 'deliverySlotReservation'
Edit
I workarrounded it with a custom mapping:
#Mapping(source = "reservationId", target = "deliverySlotReservation", qualifiedByName = "toDeliverySlotReservation")
ReservationCreateRSRDTO toReservationCreateRSRDTO(ReservationCreateODTO reservationCreateODTO);
#Named("toOrder")
public static DeliverySlotReservation toDeliverySlotReservation(String identifier) {
return new DeliverySlotReservation(identifier);
}
but still don´t know why it does not work with the normal mapping
