ModelMapper，将实体列表映射到DTO对象列表

您可以创建util类：

public class ObjectMapperUtils {    private static ModelMapper modelMapper = new ModelMapper();        static {        modelMapper = new ModelMapper();        modelMapper.getConfiguration().setMatchingStrategy(MatchingStrategies.STRICT);    }        private ObjectMapperUtils() {    }        public static <D, T> D map(final T entity, Class<D> outClass) {        return modelMapper.map(entity, outClass);    }        public static <D, T> List<D> mapAll(final Collection<T> entityList, Class<D> outCLass) {        return entityList.stream()     .map(entity -> map(entity, outCLass))     .collect(Collectors.toList());    }        public static <S, D> D map(final S source, D destination) {        modelMapper.map(source, destination);        return destination;    }}

并将其用于您的需求：

List<PostDTO> listOfPostDTO = ObjectMapperUtils.mapAll(listOfPosts, PostDTO.class);
