[开发测试]对象转换工具

maven依赖：

			<dependency>
                <groupId>com.github.dozermapper</groupId>
                <artifactId>dozer-core</artifactId>
                <version>6.5.2</version>
            </dependency>

工具类：

public class BeanMapper {

    private static final Mapper MAPPER = DozerBeanMapperBuilder.buildDefault();

    private BeanMapper() {
    }

    public static <S, D> D map(S source, Class<D> destinationClass) {
        return null == source ? null : MAPPER.map(source, destinationClass);
    }

    public static <S, D> List<D> mapList(Iterable<S> sourceList, Class<D> destinationClass) {
        if (null == sourceList) {
            return null;
        } else {
            List<D> destinationList = new ArrayList<>();

            for (S source : sourceList) {
                if (source != null) {
                    destinationList.add(MAPPER.map(source, destinationClass));
                }
            }

            return destinationList;
        }
    }

    public static <S, D> D[] mapArray(final S[] sourceArray, final Class<D> destinationClass) {
        if (null == sourceArray) {
            return null;
        } else {
            @SuppressWarnings("unchecked")
            D[] destinationArray = (D[]) Array.newInstance(destinationClass, sourceArray.length);
            int i = 0;

            for (S source : sourceArray) {
                if (source != null) {
                    destinationArray[i] = MAPPER.map(source, destinationClass);
                    ++i;
                }
            }

            return destinationArray;
        }
    }

    public static void copy(Object source, Object destinationObject) {
        MAPPER.map(source, destinationObject);
    }
}

转换list示例：

List<A> listA = new ArrayList<>();
List<B> listB = new ArrayList<>();

list = BeanMapper.mapList(listA, B.class);

list = entities.stream().map(entity -> {
      ChannelRuleDTO deliverRuleVO = new ChannelRuleDTO();
      BeanUtils.copyProperties(entity, deliverRuleVO);
      return deliverRuleVO;
  }).collect(Collectors.toList());
