Java 在 MapStruct 中，如何在 @Mapping 和 @Named 方法中使用相同的方法参数

在我的@Mapper类中，我有以下方法:

@Mapping(source = "localCar.color", target = "color")
@Mapping(source = "blueBookCar.price", target = "price")
@Mapping(source = "localCar.features", target = "features", qualifiedByName = "mapFeatures") 
abstract CarDto from(LocalCar localCar, BlueBookCar blueBookCar);

@Named("mapFeatures")
Map<Long, Feature> mapFeatures(Map<Group, Feature> features, BlueBookCar blueBookCar) {
 // do stuff with both blueBookCar and features from localCar
}

但是，我得到了一个编译错误，指出没有找到map struct方法mapFeatures(Map).

从this post开始，我try 将@Context blueBookCar用于这两种方法，但随后得到了一个错误，即它可用于在from方法中进行映射.

我能找到的唯一解决方案是传入blueBookCar两次，一次用@Context注释，一次不带注释:

@Mapping(source = "localCar.color", target = "color")
@Mapping(source = "blueBookCar.price", target = "price")
@Mapping(source = "localCar.features", target = "features", qualifiedByName = "mapFeatures") 
abstract CarDto from(LocalCar localCar, BlueBookCar blueBookCar, @Context BlueBookCar blueBookCar2)

@Named("mapFeatures")
Map<Long, Feature> mapFeatures(Map<Group, Feature> features, @Context BlueBookCar blueBookCar2) {
 //do stuff with both blueBookCar and features from localCar
}

如何在@Mapping和@Named方法中使用参数进行映射？
