简单的Socket 编程 服务端和客户端 （封装）

 由于项目需求有推送的功能，技术总监又不想用第三方极光推送，所以在同事的帮助下搭建了简单的socket通讯。

 首先服务端  java搭建

AndriodService.java

package com.android.net;import java.io.IOException;import java.net.ServerSocket;import java.net.Socket;import java.util.ArrayList;import java.util.List;public class AndroidService {// // 定义保存所有的Socket// public static List<Socket> socketList = new ArrayList<Socket>();//// public static void main(String[] args) throws IOException {// ServerSocket server = new ServerSocket(3000);// while (true) {// Socket s = server.accept();// socketList.add(s);// // 每当客户端连接之后启动一条ServerThread线程为该客户端服务// new Thread(new ServiceThreada(s)).start();//// }// }public static void main(String[] args) throws IOException {ServerSocket serivce = new ServerSocket(3000);while (true) {// 等待客户端连接Socket socket = serivce.accept();String ip = socket.getInetAddress().toString();System.out.println(System.currentTimeMillis() + "用户IP:" + ip+ " 链接了 ");new Thread(new AndroidRunable(socket)).start();}}}

AndroidRunable .java

package com.android.net;import java.io.BufferedReader;import java.io.BufferedWriter;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.ObjectInputStream;import java.io.ObjectOutputStream;import java.io.OutputStream;import java.io.OutputStreamWriter;import java.io.PrintWriter;import java.net.Socket;public class AndroidRunable implements Runnable {Socket socket = null;public AndroidRunable(Socket socket) {this.socket = socket;}public void run() {// 向android客户端输出hello worildString line = null;InputStream input;OutputStream output;String str = "hello world!";try {// 向客户端发送信息output = socket.getOutputStream();input = socket.getInputStream();// BufferedReader bff = new BufferedReader(// new InputStreamReader(input));// output.write(str.getBytes("gbk"));// output.flush(); //半关闭socket// socket.shutdownOutput();// 获取客户端的信息System.out.println(Thread.class.getName());ObjectOutputStream oos=new ObjectOutputStream(output);ObjectInputStream ois = new ObjectInputStream(input);while (true) {Object object = ois.readObject();System.out.println(object);if (object instanceof byte[]) {byte[] buff = (byte[]) object;System.out.print(new String(buff, "gbk"));}oos.writeObject("收到消息");}// 关闭输入输出流// output.close();// bff.close();// input.close();// socket.close();} catch (Exception e) {e.printStackTrace();}}}

   因为推送打开服务端要一直保持在线，所以就不关了，反正项目中的服务端不是你搭，关键在客户端是否正常。

 客户端 Andriod项目

首先我要知道客户端收到服务端信息是什么类型，其次要怎么办，怎么执行。

我这个项目是 服务端发送过来一个json  客户端解析得到要到数据，以广播的形式发送通知。

 初始化 BaseApplication 

import android.app.Application;public class BaseApplication extends Application{public static ClientSocket clientSocket;@Overridepublic void onCreate() {// TODO Auto-generated method stubsuper.onCreate();

<span style="white-space:pre"></span>//初始化clientSocket = ClientSocket.reSocket(this);}}

  清单文件的配置  注册广播  打开网络权限

 在app中使用调用   

 如果需要客户端登录后发送消息给服务端 服务端才开启对用户的推送 那么

BaseActivity

 友情提示代码中的通知 请初始化再用。

 代码都在上面 就不发demo了   客户端是封装好了的，有断线重连的过程。
