原理：移动端与服务器端通过Socket建立连接并通信。

服务器端：

package shutdownWithAndroid;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStream;import java.io.PrintStream;import java.net.ServerSocket;import java.net.Socket;public class SocketServer {    static void shutdown(){          try {                    Runtime.getRuntime().exec("shutdown -s -t 10");                }catch (Exception e) {                    e.printStackTrace();         }                                                  }         public static void main(String[] args) throws IOException{        ServerSocket  ss = new ServerSocket(30000);        while (true){            BufferedReader reader =null;            InputStreamReader isr =null;            InputStream is =null;            PrintStream ps =null;            OutputStream os =null;            Socket s = ss.accept();            is = s.getInputStream();                                                                os = s.getOutputStream();            if(is!=null){                isr = new InputStreamReader(is);                reader = new BufferedReader(isr);                String line = reader.readLine();                System.out.println(line);                if(line!=null){                    if(os!=null){                        ps = new PrintStream(os);                        ps.print("true");//                      shutdown();                        ps.close();                         System.out.println("****************************");                        }                    }                   reader.close();                }            s.close();            }    }}
