ServerAccept負責監聽接口8091,當客戶端與端口建立連接時，該類通過一個新線程啟動ServerEchoRequest類處理請求內容，并保存在目錄下的request.text中。
1.ServerAccept:
/**
*
* @author lucifer
*/
import java.net.*;
import java.io.*;
public class ServerAccept implements Runnable{
final static int LISTEN_PORT = 8091;
public void run(){
ServerSocket server = null;
try{
server = new ServerSocket(LISTEN_PORT);
System.out. }
catch(IOException e){
System.out.println("不能連接到端口:" +
LISTEN_PORT + ":" +
e.getMessage());
System.exit(0);
}
while(true){
try{
new Thread(new ServerEchoRequest(server.accept())).start();
System.out.println("啟用一個連接");
}
catch(IOException e){
System.out.println("不能接受數據:" + e.getMessage());
}
}
}
public static void main(String[] args){
new Thread(new ServerAccept()).start();
}
}
2.ServerEchoRequest:
/**
*
* @author lucifer
*/
import java.io.*;
import java.net.*;
public class ServerEchoRequest implements Runnable{
Socket m_socket = null;
final static int MAX_BUFF = 4000;
private final static int TIMEOUT = 3000;
public ServerEchoRequest(Socket socket)throws SocketException{
m_socket = socket;
}
public void run(){
try{
getClient(m_socket);
}
catch(IOException e){
System.out.println(e);
System.exit(0);
}
catch(ClassNotFoundException ex){
System.out.println(ex);
System.exit(0);
}
}
protected void getClient(Socket socket)throws IOException,ClassNotFoundException{
DataInputStream in = new DataInputStream(m_socket.getInputStream());
String s;
File f =new File("request.text");
PrintWriter fileout = new PrintWriter(new FileWriter(f));
while((s = in.readLine())!=null){
System.out.println(s);
fileout.println(s);
fileout.flush();
}
}
}
