Java可序列化对象到字节数组

准备要发送的字节数组：

ByteArrayOutputStream bos = new ByteArrayOutputStream();ObjectOutputStream 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  }}

从字节数组创建对象：

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  }}
