使用流(Stream)对java大对象备份 深度复制

[java]代码库

/**
     * 深度复制
*/
    public static Serializable deeplyCopy(Serializable src) {
        try {
            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            ObjectOutputStream oos = new ObjectOutputStream(baos);
            oos.writeObject(src);
            oos.close();
            baos.close();

            ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray());
            ObjectInputStream ois = new ObjectInputStream(bais);
            Serializable copy = (Serializable) ois.readObject();
            ois.close();
            bais.close();
            return copy;
        } catch (Exception e) {
