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响应中使用了相同的DTO对象。我想从响应中完全隐藏一些字段。

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

有没有一种方法可以根据不同的映射方法完全隐藏未映射的属性

示例

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);

}

因此调用第一个映射器[

fieldAOnlyOrderToOrderDtoMapper

将返回一个 OrderDto 对象，该对象没有名为（otherFieldB）的属性

以及第二个映射器的调用

fieldBOnlyOrderToOrderDtoMapper

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

您想忽略特定字段的IIUC。就是这样：

@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);

}

隐藏mapstruct中未映射的属性
