在mapstruct中隐藏未映射的属性

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来回应。

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

有没有办法根据不同的映射方法完全隐藏未映射的属性

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);

}

1. 因此调用第一个映射器的结果[

fieldAOnlyOrderToOrderDtoMapper

将返回一个没有命名属性的OrderDto对象（otherFieldB）

2. 和第二个映射器的调用

fieldBOnlyOrderToOrderDtoMapper

将返回一个没有命名字段的OrderDto对象（otherFiledA）

Answer 1

你想忽略特定字段的IIUC ..这样做是这样的：

@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);

}
