怎样采用java实现对windows服务的监控？

[qq_23855769]

我现在想要用java实现对windows服务的监控，并且将当时所有的服务信息记录下来，求教各位这个应该如何做到呢？

用 java实现定时重启windows指定服务,仅供参考吧：

package com.test.processManagement;  
import java.io.BufferedReader;  

import java.io.FileNotFoundException;  

import java.io.FileOutputStream;  

import java.io.IOException;  

import java.io.InputStream;  

import java.io.InputStreamReader;  

import java.io.PrintStream;  

import java.text.ParseException;  

import java.text.SimpleDateFormat;  

import java.util.Date;  

import java.util.Timer;  

import java.util.TimerTask;

那我如何能将某一时刻的所有服务记录下来呢？

[Cy_Murus]

可以Runtime执行net start，再读取取输出流。

引用 3 楼 Cy_Murus 的回复:

如果要存在文件里其实还可以简单点。 Runtime.getRuntime().exec(new String[]{"cmd /c","net start >" + 你要存放的文件路径}); 就行了

[qq_23855769]

可以再具体一点吗
