IM聊天进阶(一)IM>openfire>mina>nio>socket复习

最近APP开发，需要一个聊天功能

思路是 使用openfire

整理了一下思路：  先从最原始的开始

原始socket-->nio>mina>openfire

 今天实现，一个 服务端，多个客户端连接和会话，比较简单，了解即可

  一： 服务端

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;

public class Server1 {

 private  int port=1113;
 private  ServerSocket server;
    private static int count=0;
 
 public static void main(String[] args) {
  
           Server1 test=new Server1();
           test.begin();
 
 }
 
 public void begin()
 {
  try {
   server = new ServerSocket(port);
   while(true)
   {
    Socket  socket = server.accept();
    MyThread sunthread= new MyThread(socket,count);
    sunthread.start();
    count++;
   }
  }
   catch (Exception e) {
    // TODO: handle exception
   }
 }

   class MyThread extends Thread
 {
        private Socket mysocket;
        private int portname;
   public MyThread(Socket socket,int count) {
    this.mysocket=socket;
    portname=socket.getPort();
    System.out.println("第:"+count+"个客户端接入"+portname);
  }
 @Override
 public void run() {
 
  while(true)
  {
  
    BufferedReader in;
    PrintWriter outputWriter = null;
   try {
    in = new BufferedReader(new InputStreamReader( mysocket.getInputStream()));
     String line=in.readLine();
     System.out.println("服务器收到"+portname+"的消息:"+line);
      outputWriter=new PrintWriter(mysocket.getOutputStream());
      outputWriter.println("你好："+portname+"收到您的信息:"+line);
      outputWriter.flush();
   } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }

   
  }
 }
}

}

2 客户端

package socket;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;

public class TestMain {
 
 private static final String HOSTNAME = "127.0.0.1";
    private static final int PORT = 1113;
   
   
 public static void main(String[] args) {
   String  inputstring;
   BufferedReader readin;
   PrintWriter outputWriter = null;
      try {
  Socket clientSocket=new Socket(HOSTNAME, PORT);
  System.out.println("本地port:"+clientSocket.getLocalPort());
    readin=new BufferedReader(new InputStreamReader(System.in));
    outputWriter=new PrintWriter(clientSocket.getOutputStream());
   //读
    BufferedReader inputReader=new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
  
  inputstring=readin.readLine();
  
  while (!readin.equals("bye"))
  {
   
  // System.out.println("输入的是"+inputstring);
   //往外写
   outputWriter.println(inputstring);
   outputWriter.flush();
   
   System.out.println("----》》"+inputReader.readLine());
   inputstring=readin.readLine();
  }
  
 } catch (UnknownHostException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 } catch (IOException e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
 }
 finally{
  outputWriter.close();
 }
     
     
     
     
 }

}

效果：

 服务端 启动， 客户端多run as javaapplication几次 即可生成几个客户端

服务端：

客户端：
