Question

我遇到一个问题，我的一个Mapstruct映射器未与 @Mapper(uses =

使用另一个映射器

我们的ValidationSupportNeedMapper从实体到DTO的映射。一个ValidationSupportNeedEntity包含一个ActivityEntity属性，我正试图从该属性映射到一个Activity DTO。

因此，问题在于嵌套对象，即ActivityEntity至Activity。

这是源代码：

来自 ValidationSupportNeedMapper.java ：

@Mapper(uses = {LifecycleErrorMessagesMapper.class, ActivityMapper.class})
public interface ValidationSupportNeedMapper {

   ValidationSupportNeed toValidationSupportNeed(ValidationSupportNeedEntity source);

...

来自 ActivityMapper.java ：

@Component
public class ActivityMapper {

    public Activity toActivity(ActivityEntity activity) {
       //Implementation
    }

    public ActivityEntity toActivityEntity(Activity activity) {
        //Implementation
    }

}

来自 ValidationSupportNeedEntity.java （实体）

public class ValidationSupportNeedEntity {

    private ActivityEntity activityEntity;

来自 ValidationSupportNeed.java （DTO）

public class ValidationSupportNeed implements AutoValidated {
      private Activity validationActivity;

然而，Mapstruct似乎忽略了uses=批注上的 @Mapper 属性，并继续生成其自己的映射方法，如下所示：

   @Override
    public ValidationSupportNeed toValidationSupportNeed(ValidationSupportNeedEntity source) {
        if ( source == null ) {
            return null;
        }

        ValidationSupportNeed validationSupportNeed = new ValidationSupportNeed();

        validationSupportNeed.setValidationActivity( validationSupportNeedEntityToActivity( source ) );
    ...
  }

    protected Activity validationSupportNeedEntityToActivity(ValidationSupportNeedEntity validationSupportNeedEntity) {
        if ( validationSupportNeedEntity == null ) {
            return null;
        }

        Activity activity = new Activity();

        activity.setCode( validationSupportNeedEntity.getValidationActivityCode() );

        return activity;
    }

我想念什么？有人可以帮忙吗？

编辑：ActivityMapper未自动连接到ValidationSupportNeedMapper实现中。

添加映射注释可解决此问题：

@Mapping(source = "activityEntity", target = "validationActivity")
ValidationSupportNeed toValidationSupportNeed(ValidationSupportNeedEntity source);

请注意，属性名称不同。

Mapstruct @Mapper的uses属性不起作用
