根据参考指南，我正在学习使用MapStruct。月食verion是

面向Web开发人员的Eclipse。版本:开普勒服务第2版

pom.xml与参考指南相同

@Mapper
public interface CarMapper {

    CarMapper INSTANCE = Mappers.getMapper(CarMapper.class);

    @Mapping(source = "name", target = "fullName")
    CarDto car2CarDto(Car car);
}

添加M2E插件后，使用mvn clean install并生成代码.
