/** * Created by Liwei on 2016/7/17. * 模拟一个简单的聊天室程序 * 通过多线程改进刚开的聊天程序，这样我们就可以实现在一个窗口发送和接收数据了 */public class MainChatRoom {    public static void main(String[] args) throws SocketException {        // 作为发送端的 Socket        DatagramSocket dsSend = new DatagramSocket();        // 作为接收端的 Socket ，要指定端口        DatagramSocket dsReceive = new DatagramSocket(10086);        SendThread sendThread = new SendThread(dsSend);        ReceiveThread receiveThread = new ReceiveThread(dsReceive);        Thread t1 = new Thread(sendThread);        Thread t2 = new Thread(receiveThread);        t1.start();        t2.start();    }}

发送端线程：

public class SendThread implements Runnable {    private DatagramSocket datagramSocket;    /**     * 通过构造方法接收外部传递进来的 Socket 对象     * @param datagramSocket     */    public SendThread(DatagramSocket datagramSocket){        this.datagramSocket = datagramSocket;    }    @Override    public void run() {        try {            // 封装键盘录入数据            BufferedReader br =                    new BufferedReader(new InputStreamReader(System.in));            String line = null;            while ((line = br.readLine())!=null){                if("886".equals(line)){                    break;                }                byte[] bys = line.getBytes();                DatagramPacket dp =                        new DatagramPacket(bys,bys.length, InetAddress.getByName("192.168.100.112"),10086);                // 发送数据                datagramSocket.send(dp);            }            // 释放资源            datagramSocket.close();        } catch (IOException e) {            e.printStackTrace();        }    }}

接收端线程：

public class ReceiveThread implements Runnable {    private DatagramSocket datagramSocket;    public ReceiveThread(DatagramSocket datagramSocket) {        this.datagramSocket = datagramSocket;    }    @Override    public void run() {        try {            byte[] bys = new byte[1024];            while (true) {                DatagramPacket dp = new DatagramPacket(bys, bys.length);                // 接收数据                datagramSocket.receive(dp);                // 解析数据                String ip = dp.getAddress().getHostAddress();                String data = new String(dp.getData(),0,dp.getLength());                System.out.println("从 ip "+ ip + " 接收到数据：" + data);            }        } catch (IOException e) {            e.printStackTrace();        }        // 接收端，不要关闭 Socket    }}
