如何使用JHipster映射mapstruct中的对象引用？

<dependency>
    <groupId>org.mapstruct</groupId>
    <artifactId>mapstruct</artifactId>
    <version>1.4.2.Final</version>
</dependency>

@Mapper(componentModel = "spring")
public interface EntityMapper {

    EntityDTO entityToEntityDTO(Entity entity);

    Entity entityDTOToEntity(EntityDTO entityDTO);
}

@Mapper(componentModel = "spring")
public interface EntityMapper {

    @Mapping(source = "entityReference", target = "entityReferenceDTO")
    EntityDTO entityToEntityDTO(Entity entity);

    @Mapping(source = "entityReferenceDTO", target = "entityReference")
    Entity entityDTOToEntity(EntityDTO entityDTO);
}

@Service
public class EntityService {

    private final EntityMapper entityMapper;

    public EntityService(EntityMapper entityMapper) {
        this.entityMapper = entityMapper;
    }

    public EntityDTO getEntityDTO(Entity entity) {
        return entityMapper.entityToEntityDTO(entity);
    }

    public Entity getEntity(EntityDTO entityDTO) {
        return entityMapper.entityDTOToEntity(entityDTO);
    }
}
