安卓面試技術點之xmpp知識準備，安卓面試xmpp知識

xmpp推送和xmpp即時通訊加在簡曆上，你是可以多要1000大洋的。主要使用是用socket進行通訊的，但是現在一般使用整合架構進行開發。不過基礎我們還是需要去瞭解的。

主要需要知識點：IO流，socket基本知識

本章主要是通過郭大神講解的視頻做的總結

用戶端編寫用戶端實現的功能有：發送訊息，接收訊息 

package com.xiaoxin.client;import java.io.BufferedReader;import java.io.BufferedWriter;import java.io.IOException;import java.io.InputStreamReader;import java.io.OutputStreamWriter;import java.net.Socket;public class socketClient {/** * 讀取我們輸入資訊 */private BufferedReader readClientPrintMsg;/** * 讀取伺服器資訊 */private BufferedReader serverToClientMsg;/** * 發送資訊 */private BufferedWriter ClientToServerMsg;private Socket socket;public static void main(String[] args) {//socket用戶端socketClient client=new socketClient();client.start();}private void start() {try {socket = new Socket("127.0.0.1",9898);ClientToServerMsg = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));readClientPrintMsg = new BufferedReader(new InputStreamReader(System.in));serverToClientMsg = new BufferedReader(new InputStreamReader(socket.getInputStream()));//輸入資訊String readerConetnt;//將我們輸入的資訊發送出去while(!(readerConetnt=readClientPrintMsg.readLine()).equals("bye")){//System.out.println(readerConetnt);ClientToServerMsg.write(readerConetnt+"\n");ClientToServerMsg.flush();String serverToMsg = serverToClientMsg.readLine();System.out.println(serverToMsg);}} catch (IOException e) {e.printStackTrace();}finally{try {//關閉流socket.close();ClientToServerMsg.close();readClientPrintMsg.close();serverToClientMsg.close();} catch (IOException e) {e.printStackTrace();}}}}

伺服器端編寫伺服器端實現功能主要是：發送訊息，接收訊息

package com.xiaoxin.socketServer;import java.io.BufferedReader;import java.io.BufferedWriter;import java.io.IOException;import java.io.InputStreamReader;import java.io.OutputStreamWriter;import java.net.ServerSocket;import java.net.Socket;public class SocketServer {/** * Socket伺服器 */private ServerSocket socket;//接受資訊private BufferedReader clientToServerMsg;//發送資訊private BufferedWriter serverToClientMsg;private Socket client;public static void main(String[] args) {SocketServer server=new SocketServer();server.startServer();}public void startServer(){try {//連接埠為9898socket = new ServerSocket(9898);System.out.println("伺服器端啟動");//進入阻塞狀態，等待用戶端介入 ,返回一個socket對象client = socket.accept();System.out.println("用戶端"+socket.hashCode()+"串連上");clientToServerMsg = new BufferedReader(new InputStreamReader(client.getInputStream()));serverToClientMsg = new BufferedWriter(new OutputStreamWriter(client.getOutputStream()));String readermsg;//一行一行讀取賦值while ((readermsg=clientToServerMsg.readLine())!=null) {System.out.println(readermsg);serverToClientMsg.write("伺服器回複"+readermsg+"\n");serverToClientMsg.flush();  }} catch (IOException e) {e.printStackTrace();}finally{try {client.close();clientToServerMsg.close();socket.close();serverToClientMsg.close();} catch (IOException e) {e.printStackTrace();}}}}
