Mapstruct@Mapper的uses属性无效

@Mapper(uses =

我们的 ValidationSupportNeedMapper 从实体到DTO的映射。一个 ValidationSupportNeedEntity 包含 ActivityEntity 属性,我试图从这个属性映射到 Activity

因此,问题在于嵌套对象,即。 到 活动 .

以下是源代码:

从 验证支持NeedMapper.java

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

   ValidationSupportNeed toValidationSupportNeed(ValidationSupportNeedEntity source);

...

从 :

@Component
public class ActivityMapper {

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

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

}

从

public class ValidationSupportNeedEntity {

    private ActivityEntity activityEntity;

从 验证支持需求.java (DTO)

public class ValidationSupportNeed implements AutoValidated {
      private Activity validationActivity;

uses= 属性 @Mapper 注释并继续生成自己的映射方法,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;
    }

我错过了什么?有人能帮忙吗?

编辑 : ActivityMapper 不是自动连接到 验证支持NeedMapper 实施。
