MapstructqualifiedByName多参数

Question

创建MeaDto

映射器

映射器Impl

@Named("createMealToEntity")
@Mapping(source = "restaurantId", target = "restaurantId")
@Mapping(ignore = true, target = "mealId")
Meal createMealToEntity(CreateMealDto createMealDto,String restaurantId);

@IterableMapping(qualifiedByName = "createMealToEntity")
List<Meal> createListMealToEntity(List<CreateMealDto> createMealDtoList, String restaurantId);

我需要使用参数将 object 的列表重载为 object。

映射器

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


@Named("createMealToEntity")
@Mapping(source = "restaurantId", target = "restaurantId")
@Mapping(ignore = true, target = "mealId")
Meal createMealToEntity(CreateMealDto createMealDto,String restaurantId);

@IterableMapping(qualifiedByName = "createMealToEntity")
List<Meal> createListMealToEntity(List<CreateMealDto> createMealDtoList, String restaurantId);

List<MealDto> entityToDto(List<Meal> mealList);
}

public class CreateMealDto {
    private String name;
    private Double price;
    private String imageUrl;

    private Double timeToDo;
}

@GeneratedValue(generator = "UUID")
@GenericGenerator(
        name = "UUID",
        strategy = "org.hibernate.id.UUIDGenerator"
)
@Column(name = "meal_id")
private String mealId;

@Column(name = "name")
