@Mapper 
public interface CarMapper {
 
    CarMapper INSTANCE = Mappers.getMapper( CarMapper.class ); 
 
    @Mapping(source = "numberOfSeats", target = "seatCount")
    CarDto carToCarDto(Car car); 
}

•  我的方法：将entity映射为po对象
• 我的用法：springboot工程在service实现类中用@Autowired注入该接口并调用方法报错：绑定异常，找不到xxx包.xxx接口.fromEntityToPo()方法
• 查看官网手册发现调用转换方法的写法如下：
  

  
  @Test
  public void shouldMapCarToDto() {
      //given
      Car car = new Car( "Morris", 5, CarType.SEDAN );
   
      //when ，直接用接口名.实例对象.方法名（）调用
      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" );
  }
