Java可序列化对象到字节数组 [英] Java Serializable Object to Byte Array

问题描述

假设我有一个可序列化的类 AppMessage 。

Let's say I have a serializable class AppMessage.

我想将其作为<$ c传输$ c> byte [] 通过套接字到另一台机器，从接收的字节重建它。

I would like to transmit it as byte[] over sockets to another machine where it is rebuilt from the bytes received.

我怎么能实现这个？

推荐答案

准备要发送的字节：

ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutput out = null;
try {
  out = new ObjectOutputStream(bos);   
  out.writeObject(yourObject);
  out.flush();
  byte[] yourBytes = bos.toByteArray();
  ...
} finally {
  try {
    bos.close();
  } catch (IOException ex) {
    // ignore close exception
  }
}

从字节创建对象：

ByteArrayInputStream bis = new ByteArrayInputStream(yourBytes);
ObjectInput in = null;
try {
  in = new ObjectInputStream(bis);
  Object o = in.readObject(); 
  ...
} finally {
  try {
    if (in != null) {
      in.close();
    }
  } catch (IOException ex) {
    // ignore close exception
  }
}
