Java Socket远程关机,重启

Java Socket远程关机,重启

摘要
-通过Java Socket实现远程关机,重启命令
-以下,直接贴代码,代码实现了服务端操作,客户端响应关机,重启操作

---

客户端(执行远程命令)

package test.shutdown;

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
public class Client implements Runnable {

    String s = null;
    Socket mysocket;
    DataInputStream in = null;
    DataOutputStream out = null;
    Thread thread = null;

   public Client() {
   //初始化socket,并开启发送命令的线程
        thread = new Thread(this); 
        try {
            //线程休眠
            Thread.sleep(500);
            mysocket = new Socket("localhost", 9090);//localhost可修改为连接服务端的IP地址
            //下面是初始化流
            in = new DataInputStream(mysocket.getInputStream());
            out = new DataOutputStream(mysocket.getOutputStream());
        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (Exception e) {
        }
        //开启发送命令的线程
        thread.start();
    }
//入口方法
    public static void main(String args[]) {
        new Client();
    }
    //执行命令的方法
    public void ExeCmd(String s) {
        try {
            Runtime ec = Runtime.getRuntime();
            ec.exec(s);
        } catch (IOException e) {

            e.printStackTrace();
        }
    }

    public void run() {
        while (true) {
            try {
                //读取远程命令
                String s = in.readUTF();
                ExeCmd(s);//调用方法运行远程命令
                Thread.sleep(200);
            } catch (Exception e) {
            }

            try {
            //每执行一个命令,需要休眠      
                Thread.sleep(200);   
                  } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}

服务端(发送远程命令)

“`
package test.shutdown;

/**
* Created by zqq3436 on 2017/3/14.
*/
import java.net.*;
import java.io.*;

public class Server {
ServerSocket server=null;
Socket you=null;
String s=null;
DataOutputStream out=null;
public Server(){
//初始化ServerSocket
try{
server=new ServerSocket(9090);
System.out.println(“wait…..”);
you=server.accept();
//初始化输出流
out=new DataOutputStream(you.getOutputStream());
}catch(Exception e){
}

}
//入口方法,开启远程发送命令线程
public static void main(String args[])
{
    Server server=new Server();
    //打开对方的控制台
    server.sendOrder("mmc");
    //每发送一个命令,需要休眠     
    try{Thread.sleep(500);}catch(Exception e){} 
    server.sendOrder("shutdown -s -t 5");// 让对方在5秒内关机,"shutdown -r -t 5"表示5秒内重启
    //每发送一个命令,需要休眠 
    try{Thread.sleep(500);}catch(Exception e){}
    server.sendOrder("shutdown -a");//取消关机

}

//发送命令的方法
public void sendOrder( String s)
{
try{
out.writeUTF(s);
}catch(Exception e){
}
}

}

尾注
-此处,也可以更改为使客户端发送命令,服务器端执行远程命令,代码极为相似,这里不再举出
