本文介绍如何使用Java通过Socket实现对象的远程传输。具体方法为利用对象序列化技术，结合ObjectOutputStream与ObjectInputStream来完成Java对象的数据交换。客户端发送Employee对象到服务器端，服务器端修改后再返回。

　　这篇文章主要实现的是j：通过socket传递Java对象。采用的方法就是对象序列化。方法是：通过socket建立c/s连接；通过ObjectOutputStream，ObjectOutputStream 读写对象。唯一需要留意的是传递的java 对象需要实现Serializable标记接口。代码包括：java对象类，Employee; socket client类；server类。主要代码如下：
　　java对象类：
　　import java.io.*;
　　import java.util.*;
　　public class Employee implements Serializable {
　　private int employeeNumber;
　　private String employeeName;
　　Employee(int num, String name) {
　　employeeNumber = num;
　　employeeName= name;
　　}
　　public int getEmployeeNumber() {
　　return employeeNumber ;
　　}
　　public void setEmployeeNumber(int num) {
　　employeeNumber = num;
　　}
　　public String getEmployeeName() {
　　return employeeName ;
　　}
　　public void setEmployeeName(String name) {
　　employeeName = name;
　　}
　　}
　　client类：
　　import java.io.*;import java.net.*;public class Client { public static void main(String[] arg) { try { Employee joe = new Employee(150, "Joe"); System.out.println("employeeNumber= " + joe .getEmployeeNumber()); System.out.println("employeeName= " + joe .getEmployeeName()); Socket socketConnection = new Socket("127.0.0.1", 11111); ObjectOutputStream clientOutputStream = new ObjectOutputStream(socketConnection.getOutputStream()); ObjectInputStream clientInputStream = new ObjectInputStream(socketConnection.getInputStream()); clientOutputStream.writeObject(joe); joe= (Employee)clientInputStream.readObject(); System.out.println("employeeNumber= " + joe .getEmployeeNumber()); System.out.println("employeeName= " + joe .getEmployeeName()); clientOutputStream.close(); clientInputStream.close(); } catch (Exception e) {System.out.println(e); } }}
　　Server类：
　　import java.io.*;
　　import java.net.*;
　　public class Server {
　　public static void main(String[] arg) {
　　Employee employee = null;
　　try {
　　ServerSocket socketConnection = new ServerSocket(11111);
　　System.out.println("Server Waiting");
　　Socket pipe = socketConnection.accept();
　　ObjectInputStream serverInputStream = new
　　ObjectInputStream(pipe.getInputStream());
　　ObjectOutputStream serverOutputStream = new
　　ObjectOutputStream(pipe.getOutputStream());
　　employee = (Employee )serverInputStream.readObject();
　　employee .setEmployeeNumber(256);
　　employee .setEmployeeName("John");
　　serverOutputStream.writeObject(employee);
　　serverInputStream.close();
　　serverOutputStream.close();
　　} catch(Exception e) {System.out.println(e);
　　}
　　}
　　}
