List拷贝方法

需要使用 import org.apache.commons.beanutils.BeanUtils;

/**
	 * 复制集合
	 * @param <E>
	 * @param source
	 * @param destinationClass
	 * @return
	 * @throws InstantiationException 
	 * @throws InvocationTargetException 
	 * @throws IllegalAccessException 
	 */
	public static <E> List<E> copyTo(List<?> source, Class<E> destinationClass) throws IllegalAccessException, InvocationTargetException, InstantiationException{
		if (source.size()==0) return Collections.emptyList();
		List<E> res = new ArrayList<E>(source.size());
		for (Object o : source) {
			E e = destinationClass.newInstance();
			BeanUtils.copyProperties(e, o);
			res.add(e);
		}
		return res;
	}
