[JAVA] 深克隆 另外实现方法【序列化】

private static List cloneObject(
   Object obj) throws Exception {
  ByteArrayOutputStream byteOut = new ByteArrayOutputStream();
  ObjectOutputStream out = new ObjectOutputStream(byteOut);
  out.writeObject(obj);
  ByteArrayInputStream byteIn = new ByteArrayInputStream(byteOut
    .toByteArray());
  ObjectInputStream in = new ObjectInputStream(byteIn);
  return  in.readObject();
 }
