TCP Socket编程--客户端和服务端双向通信

好久没有写javaeye博客了，最近写了个TCP Socket编程，和大家一起分享！

服务端：

package test;import java.io.BufferedReader;import java.io.DataInputStream;import java.io.DataOutputStream;import java.io.IOException;import java.io.InputStreamReader;import java.net.ServerSocket;import java.net.Socket;public class TCPServer2 {/** * @param args * @throws IOException  */public static void main(String[] args) throws IOException {new TCPServer2().go();}public void go(){ServerSocket ss;Socket s = null;try {ss = new ServerSocket(8888);s = ss.accept();} catch (IOException e) {e.printStackTrace();}SendThread send = new SendThread(s);new Thread(send).start();RecvThread recv = new RecvThread(s);new Thread(recv).start();}class SendThread implements Runnable{private Socket s = null;private DataOutputStream dos = null;public SendThread(Socket s){this.s = s;try {dos = new DataOutputStream(s.getOutputStream());} catch (IOException e) {e.printStackTrace();}}@Overridepublic void run() {String str = ""; while(true){System.out.println("input message:");BufferedReader br = new BufferedReader(new InputStreamReader(System.in));try {str = br.readLine();dos.writeUTF(str);if("bye".equals(str))break;} catch (IOException e) {e.printStackTrace();}}}}class RecvThread implements Runnable{private Socket s = null;private DataInputStream dis = null;public RecvThread(Socket s){this.s = s;try {dis = new DataInputStream(s.getInputStream());} catch (IOException e) {e.printStackTrace();}}@Overridepublic void run() {String str = "";while(true){try {str = dis.readUTF();if("bye".equals(str))break;System.out.println("received message:"+str);} catch (IOException e) {e.printStackTrace();}}}}}

客户端：

package test;import java.io.BufferedReader;import java.io.DataInputStream;import java.io.DataOutputStream;import java.io.IOException;import java.io.InputStreamReader;import java.net.Socket;import java.net.UnknownHostException;public class TCPClient2 {public static void main(String[] args) throws UnknownHostException, IOException{new TCPClient2().go();}public void go() {try {Socket s = new Socket("127.0.0.1",8888);RecvThread recv = new RecvThread(s);new Thread(recv).start();SendThread send = new SendThread(s);new Thread(send).start();} catch (UnknownHostException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}class RecvThread implements Runnable{private Socket s = null;private DataInputStream dis = null;public RecvThread(Socket s){this.s = s;try {dis = new DataInputStream(s.getInputStream());} catch (IOException e) {e.printStackTrace();}}@Overridepublic void run() {String str = "";while(true){try {str = dis.readUTF();if("bye".equals(str))break;System.out.println("received message:"+str);} catch (IOException e) {e.printStackTrace();}}}}class SendThread implements Runnable{private Socket s;private DataOutputStream dos;public SendThread(Socket s){this.s = s;try {dos = new DataOutputStream(s.getOutputStream());} catch (IOException e) {e.printStackTrace();}}@Overridepublic void run() {String str = "";while(true){System.out.println("input message:");BufferedReader br = new BufferedReader(new InputStreamReader(System.in));try {str = br.readLine();dos.writeUTF(str);if("bye".equals(str))break;} catch (IOException e) {e.printStackTrace();}}}}}
