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();

}

}

@Override

public 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();

}

}

@Override

public 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();

}

}

@Override

public 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();

}

}

@Override

public 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();

}

}

}

}

}
