前面两篇文章介绍了怎样建立Java Socket通信，这一篇说一下怎样使用Java Socket来传输对象。

首先需要一个普通的对象类，由于需要序列化这个对象以便在网络上传输，所以实现java.io.Serializable接口就是必不可少的了，入下：

package com.googlecode.garbagecan.test.socket.sample3;public class User implements java.io.Serializable { private static final long serialVersionUID = 1L; private String name; private String password; public User() {   }  public User(String name, String password) {  this.name = name;  this.password = password; }  public String getName() {  return name; } public void setName(String name) {  this.name = name; } public String getPassword() {  return password; } public void setPassword(String password) {  this.password = password; }}

对于Server端的代码，代码中分别使用了ObjectInputStream和ObjectOutputStream来接收和发送socket中的InputStream和OutputStream，然后转换成Java对象，如下：

package com.googlecode.garbagecan.test.socket.sample3;import java.io.*;import java.net.ServerSocket;import java.net.Socket;import java.util.logging.Level;import java.util.logging.Logger;public class MyServer { private final static Logger logger = Logger.getLogger(MyServer.class.getName());  public static void main(String[] args) throws IOException {  ServerSocket server = new ServerSocket(10000);  while (true) {   Socket socket = server.accept();   invoke(socket);  } } private static void invoke(final Socket socket) throws IOException {  new Thread(new Runnable() {   public void run() {    ObjectInputStream is = null;    ObjectOutputStream os = null;    try {     is = new ObjectInputStream(new BufferedInputStream(socket.getInputStream()));     os = new ObjectOutputStream(socket.getOutputStream());     Object obj = is.readObject();     User user = (User)obj;     System.out.println("user: " + user.getName() + "/" + user.getPassword());     user.setName(user.getName() + "_new");     user.setPassword(user.getPassword() + "_new");     os.writeObject(user);     os.flush();    } catch (IOException ex) {     logger.log(Level.SEVERE, null, ex);    } catch(ClassNotFoundException ex) {     logger.log(Level.SEVERE, null, ex);    } finally {     try {      is.close();     } catch(Exception ex) {}     try {      os.close();     } catch(Exception ex) {}     try {      socket.close();     } catch(Exception ex) {}    }   }  }).start(); }}

Client也和Server端类似，同样使用ObjectOutputStream和ObjectInputStream来处理，如下：

package com.googlecode.garbagecan.test.socket.sample3;import java.io.BufferedInputStream;import java.io.IOException;import java.io.ObjectInputStream;import java.io.ObjectOutputStream;import java.net.Socket;import java.util.logging.Level;import java.util.logging.Logger;public class MyClient {  private final static Logger logger = Logger.getLogger(MyClient.class.getName());  public static void main(String[] args) throws Exception {  for (int i = 0; i < 100; i++) {   Socket socket = null;   ObjectOutputStream os = null;   ObjectInputStream is = null;      try {    socket = new Socket("localhost", 10000);     os = new ObjectOutputStream(socket.getOutputStream());    User user = new User("user_" + i, "password_" + i);    os.writeObject(user);    os.flush();        is = new ObjectInputStream(new BufferedInputStream(socket.getInputStream()));    Object obj = is.readObject();    if (obj != null) {     user = (User)obj;     System.out.println("user: " + user.getName() + "/" + user.getPassword());    }   } catch(IOException ex) {    logger.log(Level.SEVERE, null, ex);   } finally {    try {     is.close();    } catch(Exception ex) {}    try {     os.close();    } catch(Exception ex) {}    try {     socket.close();    } catch(Exception ex) {}   }  } }}

最后测试上面的代码，首先运行Server类，然后运行Client类，就可以分别在Server端和Client端控制台看到接收到的User对象实例了。
