Pile technologique utilisée :
Java 8 MapStruct : 1.2.0.Final Lombok : 1.16.18 IDE : IntelliJ - Plugin Lombok déjà installé
- Au départ, j'ai rencontré des problèmes lorsque j'ai supprimé les getters et setters et ajouté des
@Getteret@Setterannotation,mapstructn'est pas en mesure de trouver la propriété et dit :Unknown property "id" in result type com.vg.once.dto.OneDto. Did you mean "null"? - J'ai appris que Lombok 1.16.14 ou une version plus récente et MapStruct 1.2.0.Beta1 ou une version plus récente sont compatibles et peuvent fonctionner ensemble, mais mes versions sont plus récentes que celles souhaitées et le problème persiste.
- Une autre solution que j'ai déjà essayée est d'utiliser le plugin Delombok de Lombok, mais le même problème se pose toujours.
Voici les fichiers du projet :
L'objet entité : One.java :
import lombok.Getter;
import lombok.Setter;
@Getter
@Setter
public class One {
private int id;
private Integer version;
private int projectId;
private String title;
private String code;
private int sortOrder;
}L'objet DTO : OneDTO.java :
import lombok.Getter;
import lombok.Setter;
@Getter
@Setter
public class OneDto {
private int id;
private Integer version;
private int projectId;
private String title;
private String code;
private int sortOrder;
}Classe Mapper : OneMapper.java
import org.mapstruct.Mapper;
import org.mapstruct.Mapping;
import com.vg.once.dto.OneDto;
import com.vg.once.entity.One;
@Mapper
public interface OneMapper {
@Mapping(target="id", source="one.id")
OneDto createOne (One one);
