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,如下:
- 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) {}
- }
- }
- }
- }
***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。
