写了一个javaSocket通信的例子，比较容易懂，主要是TCP协议的。下面是服务端的代码
Java代码
import java.io.IOException;
import java.net.InetAddress;
import java.net.Socket;
public class ServerSocket {
public static void main(String[] args) {
beginSocket();
}
public static void beginSocket(){
try {
java.net.ServerSocket serverSocket=new java.net.ServerSocket(3456);
InetAddress inta=serverSocket.getInetAddress().getLocalHost();
System.out.println(inta.getHostAddress());
while(true){
Socket socket=serverSocket.accept();
new HelloMessage(socket);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
为了提高并发时的处理效率，对于每个请求，系统都新建一个线程处理。
Java代码
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
public class HelloMessage extends Thread {
private Socket socket_ = null;
public HelloMessage(Socket socket) {
this.socket_ = socket;
this.start();
}
public void run() {
try {
BufferedReader bReader = new BufferedReader(new InputStreamReader(
this.socket_.getInputStream()));
PrintWriter pWriter = new PrintWriter(this.socket_
.getOutputStream());
String requestStr = bReader.readLine();
if (requestStr != null && !"".equals(requestStr)) {
if (requestStr.equals("java")) {
pWriter.println("your write is java");
}
if (requestStr.equals(".net")) {
pWriter.println("your write is .net");
}
if (requestStr.equals("php")) {
pWriter.println("your write is php");
}
if (requestStr.equals("end")) {
pWriter.println("your write is end");
}else{
pWriter.println("your write is other");
}
