通過tomcat的服務來關閉tomcat

在tomcat的配置文件server.xml中的第一行往往是<Server port="8005" shutdown="SHUTDOWN">

其含義是可以通過網絡來關閉tomcat(只能在本機)。於是嘗試了一下。java代碼如下:

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

public class Test{
	public static void main(String[] args){
		try{
			System.out.println("本程序用來停止tomcat.");
			
			System.out.println("請輸入停止tomcat的端口號(默認爲8005)");
			BufferedReader reader=new BufferedReader(new InputStreamReader(System.in));
			String s=reader.readLine();
			if(s.isEmpty())
				s=new String("8005");
			int stopPort=Integer.parseInt(s);
			
			System.out.println("請輸入停止tomcat的字符串(默認爲\"SHUTDOWN\")");
			reader=new BufferedReader(new InputStreamReader(System.in));
			s=reader.readLine();
			if(s.isEmpty())
				s=new String("SHUTDOWN");
			String stopString=new String(s);
			
			Socket socket=new Socket("127.0.0.1",stopPort);
			
			PrintWriter out=new PrintWriter(socket.getOutputStream());
			BufferedReader in=new BufferedReader(new InputStreamReader(socket.getInputStream()));
			
			out.print(stopString);
			out.flush();
			
			System.out.println("從tomcat返回的信息:"+in.readLine());
			socket.close();
		}catch(Exception e){
			e.printStackTrace();
		}
	}
	
}
