本文展示了如何在项目中引入MapStruct库来实现对象间的转换，并结合Lombok进行便捷的属性映射。通过创建Car和CarDto类，定义CarMapper接口，实现了Car到CarDto的自动映射功能。在测试中，验证了映射过程的正确性。

引入POM文件

创建转换接口

@Data
public class Car {
    private String make;
    private int numberOfSeats;
    private CarType type;
}
@Data
public class CarDto {
    private String make;
    private int seatCount;
    private String type;
}
@Mapper
public interface CarMapper {
    CarMapper INSTANCE = Mappers.getMapper( CarMapper.class ); 3
    //字段映射
    @Mapping(source = "numberOfSeats", target = "seatCount")
    CarDto carToCarDto(Car car); 
}

@Test
public void shouldMapCarToDto() {
    //given
    Car car = new Car( "Morris", 5, CarType.SEDAN );
 
    //when
    CarDto carDto = CarMapper.INSTANCE.carToCarDto( car );
 
    //then
    assertThat( carDto ).isNotNull();
    assertThat( carDto.getMake() ).isEqualTo( "Morris" );
    assertThat( carDto.getSeatCount() ).isEqualTo( 5 );
    assertThat( carDto.getType() ).isEqualTo( "SEDAN" );
}
