求救：如何从控制台退出程序

[wj1122]

编了一个程序，是一个Socket的Server端，用于不间断接收从clinet端来的数据；每监听到一个client端就开启一个线程接收数据，程序是用while循环不间断监听sockets的。现在偶想做一个server端的结束部分，当在控制台输入字母q时，server端退出，请问如何实现。谢谢。ps:因为这个程序想打成jar包放在linux上，在linux上运行，所以想加入退出程序的语句。谢谢。程序源代码如下

import java.io.*;
import java.net.*;
import java.util.*;

public class JavaServer {
public static void main(String[] args) throws Exception
{
System.out.println("Server starting....");
ServerSocket server=new ServerSocket(2005);
int num=0;
while(true)
{
Socket s;
s=server.accept();
System.out.println("Accepting Connection...");
num=num+1;
new ServerThread(s,num).start();

}
}


}
class ServerThread extends Thread
{

Socket s;
int sumClient;
public ServerThread(Socket ts,int sc){
s = ts;
sumClient = sc;
}
public void run(){
StringBuffer data = new StringBuffer();
String recv = "";
System.out.println("连接成功,正在接收数据...");
try{
BufferedReader sis = new BufferedReader(new InputStreamReader(s.getInputStream()));
PrintWriter sos =new PrintWriter(s.getOutputStream());
recv = sis.readLine();
while(!recv.trim().equals("bye")){
data.append("客户"+sumClient+"在时间"+Calendar.getInstance().getTime().toString());
data.append("接收到数据:"+recv);
System.out.println(data.toString());
sos.println(data.toString());
sos.flush();
recv = sis.readLine();
data.setLength(0);
}
if(recv.trim().equals("bye"))
sos.println("bye");
sos.close();
sis.close();
s.close();
}catch(Exception e){}
}


}

谢谢楼上的，请问如果在源程序中加入退出语句的话，应怎样做

在Linux上写个启动/停止的Shell脚本。给你个例子参考。
[code=BatchFile]#!/bin/bash
JAVA_HOME=XXX
APP_INSTALLATION_PATH=XXXX

APP_PID_FILE=$APP_INSTALLATION_PATH/XXXXX.pid
case "$1" in
start)
if [ -f $APP_PID_FILE ] ; then
pid=`cat $APP_PID_FILE`
if [ -n $APP_PID_FILE ] && kill -0 $pid ; then
echo "service is already running..."
exit 0
fi
fi
APP_JARS=`ls $APP_INSTALLATION_PATH/*.jar | xargs | sed 's/ /\:/g'`
APP_CLASS_NAME=ge.threatscan.gsmsmgwy.Initializer
export LD_LIBRARY_PATH=$APP_INSTALLATION_PATH
nohup $JAVA_HOME/bin/java -cp $APP_JARS $APP_CLASS_NAME &
pid=$!
echo $pid > $APP_PID_FILE
;;
stop)
[ ! -f $APP_PID_FILE ] && {
echo "pid file is missing, the service cannot be stopped"
exit 1
}
echo "shutting down the service..."
kill -9 $(cat $APP_PID_FILE)
rm -f $APP_PID_FILE
;;
restart)
$0 stop
$0 start
;;
*)
echo "Usage: $0 <start|stop|restart>"
exit 1
esac
exit 0[/code]

你需要改下。不好意思，那是我的启动class。
