Mapstruct-为从基类继承的所有类生成映射程序

Question

我有一个Mapstruct映射器，用于将传入请求与现有数据合并-映射器看起来像这个

@Mapper(uses = ProtoMapperUtil.class,
collectionMappingStrategy = CollectionMappingStrategy.ADDER_PREFERRED,
unmappedTargetPolicy = ReportingPolicy.IGNORE,
nullValueCheckStrategy = NullValueCheckStrategy.ALWAYS)
public interface FooEntityMapper extends BaseMapper<FooEntity> {
FooEntityMapper INSTANCE = Mappers.getMapper(FooEntityMapper.class);
}

BaseMapper看起来像这个

public interface BaseMapper<T extends BaseEntity> {
T merge(T var1, @MappingTarget T var2);
}

考虑到我有多个像FooEntity这样的实体，并且它们都扩展了BaseEntity，我必须为这些实体中的每一个手动定义一个映射器——我实际上不需要这样做，因为功能不会在类之间发生变化。有没有一种方法可以在全局级别(？(上定义Mapstruct属性，以便它自动为从BaseEntity扩展的每个bean生成一个映射器？

Answer 1

和您一样，我在旧项目中使用了BaseEntity。这就是我配置映射程序的方式。

public interface BaseMapper {
BaseEntity toBaseEntity(BaseDTO baseDTO);

BaseDTO toBaseDTO(BaseEntity baseEntity);
}    

在foo映射器上，您必须将BaseMapper添加为config。

@Mapper(
config = BaseMapper.class,
uses = { ProtoMapperUtil.class,
collectionMappingStrategy = CollectionMappingStrategy.ADDER_PREFERRED,
unmappedTargetPolicy = ReportingPolicy.IGNORE,
nullValueCheckStrategy = NullValueCheckStrategy.ALWAYS})
public interface FooEntityMapper {
FooEntityMapper INSTANCE = Mappers.getMapper(FooEntityMapper.class);
//I don't remember if you need or not to declare the @InheritConfiguration
//@InheritConfiguration(name = "toBaseDTO")
FooDTO toFooDTO(FooEntity fooEntity)
}
