如何在Java中反序列化

Question

是Java Networking的新手，我正在尝试使用datagramPacket反序列化通过网络发送的消息。但我得到了不同的东西。以下是代码。

发送代码

public static void main(String[] args) {
try{
     String host = "localhost";
    InetAddress addr = InetAddress.getByName(host);
    NewClass Details = new NewClass("Jay", 1);
    ByteArrayOutputStream buffer = new ByteArrayOutputStream();
    ObjectOutputStream In = new ObjectOutputStream(buffer);
    In.writeObject(Details);
    In.flush();

    byte[] Buf= buffer.toByteArray();
    DatagramPacket packet = new DatagramPacket(Buf, Buf.length, addr, 7000);
    DatagramSocket socket = new DatagramSocket(4000);
    socket.send(packet);
            }catch (Exception error){
                    error.printStackTrace();
             }
     }

接收代码

 public static void main(String[] args) {

    try {
         DatagramSocket socket = new DatagramSocket(7000);
         socket.setSoTimeout(0);
           while (true) {
         byte[] buffer = new byte[1024];
         DatagramPacket packet = new DatagramPacket(buffer, buffer.length);
         socket.receive(packet);
         String message = new String(buffer);
         System.out.println(message.trim());
            }
     } catch (Exception error) {
          error.printStackTrace();
         }
   }

这是打印出来的

使用ObjectInputStream。 查看ObjectInputStream API Page。
