java学习20天

今天开始写聊天室项目：

 主要思想如图所示

package com.ww.qqserve.service;

import com.ww.qqcommon.MassageType;
import com.ww.qqcommon.Message;
import com.ww.qqcommon.User;

import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.ServerSocket;
import java.net.Socket;

public class QQServer {
   private ServerSocket ss=null;
   public QQServer(){
       System.out.println("服务器在9999端口监听。。。");
       try {
           ss=new ServerSocket(9999);
           while (true){//监听是不断的
               Socket socket = ss.accept();
               ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
               User u = (User) ois.readObject();

               ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream());

               Message message=new Message();


               //先验证特殊的，因为这里需要使用到数据库
               if(u.getUserId().equals("100")&&u.getPassWd().equals("123456")){//登录成功
                message.setMesType(MassageType.MESSAGE_LOGIN_SUCCEED);
                oos.writeObject(message);
                //创建一个线程，与客户端保持联系。
                   ServerConnectClientThread serverConnectClientThread = new ServerConnectClientThread(socket, u.getUserId());
                   serverConnectClientThread.start();
                //把线程对象 放入集合中
                   
               }else{//登录失败

               }
           }

       } catch (Exception e) {
           e.printStackTrace();
       }

   }

}

package com.ww.qqserve.service;

import com.ww.qqcommon.Message;

import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.net.Socket;

public class ServerConnectClientThread extends Thread {
    private Socket socket;
    private String userId;//链接到服务器的id

    public ServerConnectClientThread(Socket socket, String userId) {
        this.socket = socket;
        this.userId = userId;
    }

    @Override
    public void run() {
        while(true){
            System.out.println("服务端与客户端保持通讯，读取数据");
            try {
                ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
                Message me = (Message) ois.readObject();
                //后面会使用messa

            } catch (Exception e) {
                e.printStackTrace();
            }


        }
    }
}
