隐藏mapstruct中未映射的属性

Question

我正在使用DTO对象从spring rest控制器中的@RequestBody中检索信息，并在json响应中使用相同的DTO对象。我想完全隐藏一些字段不让响应。

我尝试了@BeanMapping(ignoreByDefault=true)，它为未映射的属性返回null，但我的问题是：

public Class Order {
private Long id;
private String name;
private String otherField;
}

public Class OrderDto {
private Long id;
private String name;
private String otherFieldA
private String otherFieldB;
}

@Mapper
public interface OrderMapper

//..

@Mappings({
  @Mapping(target = "id", source ="id"),
  @Mapping(target = "name", source ="name"),
  @Mapping(target = "otherFieldA", source ="otherField")
  })
@BeanMapping(ignoreByDefault = true)
OrderDto fieldAOnlyOrderToOrderDtoMapper(Order order);


@Mappings({
  @Mapping(target = "id", source ="id"),
  @Mapping(target = "name", source ="name"),
  @Mapping(target = "otherFieldB", source ="otherField")
  })
@BeanMapping(ignoreByDefault = true)
OrderDto fieldBOnlyOrderToOrderDtoMapper(Order order);

}

null

FieldBonlyOrderToOrderToMapper

将返回一个OrderDto对象，该对象没有名为（otherFiledA）的字段

要忽略特定字段得IIUC..是这样做的：

@Mapper
public interface OrderMapper

//..

@Mapping(target = "otherFieldA", source ="otherField")
@Mapping(target = "otherFieldB", ignore=true")
OrderDto fieldAOnlyOrderToOrderDtoMapper(Order order);


@Mapping(target = "otherFieldA", ignore=true)
@Mapping(target = "otherFieldB", source ="otherField")
OrderDto fieldBOnlyOrderToOrderDtoMapper(Order order);

}
