数组List深拷贝：

public static  List deepCopy(List src) throws IOException, ClassNotFoundException {
        ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
        ObjectOutputStream outputStream = new ObjectOutputStream(byteArrayOutputStream);
        outputStream.writeObject(src);

        ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(byteArrayOutputStream.toByteArray());
        ObjectInputStream inputStream = new ObjectInputStream(byteArrayInputStream);
        List dest = (List) inputStream.readObject();
        return dest;

    }
