参考代码太简单了，比如遇到循环引用对象怎么办？

嗯，可以把你的答案贡献出来。

  /**
   * This method makes a "deep clone" of any object it is given.
   * 
   * @param object origin target should implement Serializable
   */
  public static Object deepClone(Object object) {
    try {
      ByteArrayOutputStream baos = new ByteArrayOutputStream();
      ObjectOutputStream oos = new ObjectOutputStream(baos);
      oos.writeObject(object);
      ByteArrayInputStream bais = new ByteArrayInputStream(baos.toByteArray());
      ObjectInputStream ois = new ObjectInputStream(bais);
      return ois.readObject();
    }
    catch (Exception e) {
      e.printStackTrace();
      return null;
    }
  }
}

@nttd-junchu 对的,可以通过序列化实现深复制
