java - 在 mapstruct 中将 List 转换为 List 时如何定义源和目标？

Question

I am Trying to converting List<car> to List<CarDto> but not able to map source and target attribute in mapstruct. Source and target mapping working fine when I convert Car to CarDto but its not working with list<car> object

@Mapper
public interface CarMapper {

     @Mappings({
            @Mapping(source = "carDetailDetail.model", target = "model")
        })
    List<CarDto> carsToCarDtos(List<Car> cars);


}

Answer 1

MapStruct 不支持您正在寻找的内容，已经有一个开放的功能请求，请查看 #1149 .

但是，为了使该工作正常进行，您需要在 Car 和 CarDto 之间的方法上定义映射，然后 MapStruct 将使用该方法执行映射.

你的映射器看起来像:

@Mapper
public interface CarMapper {

    @Mapping(source = "carDetailDetail.model", target = "model")
    CarDto carToCarDto(Car car);

    List<CarDto> carsToCarDtos(List<Car> cars);       
}

如果您不想公开一个公共(public)的carToCarDto 方法，您可以使用一个抽象类并将该方法设为protected 或package protected.
