用java打包成jar可执行文件并执行windows定时任务

1、写一个音乐播放java类

package com.rupeng.test2;

import javax.sound.midi.MidiEvent;
import javax.sound.midi.MidiSystem;
import javax.sound.midi.Sequence;
import javax.sound.midi.Sequencer;
import javax.sound.midi.ShortMessage;
import javax.sound.midi.Track;

public class MiniMusicApp {
public static void main(String[] args) {
MiniMusicApp mini = new MiniMusicApp();
mini.play();
}

public void play() {
try {
// Get a sequencer and open it
Sequencer player = MidiSystem.getSequencer();
player.open();

Sequence seq = new Sequence(Sequence.PPQ, 4); //Treat the arguments as Ready-bake arguments

Track track = seq.createTrack(); // Ask the sequence for a track

// Put some MidiEvents into the Track, the setMessage() method is what we should really care
ShortMessage a = new ShortMessage();
a.setMessage(144, 1, 44, 100);
MidiEvent noteOn = new MidiEvent(a, 1);
track.add(noteOn);

ShortMessage b = new ShortMessage();
b.setMessage(128, 1, 44, 100);
MidiEvent noteOff = new MidiEvent(b, 16);
track.add(noteOff);

player.setSequence(seq); // Give the sequence to the Sequencer
// like pushing a CD to a CD player

player.start();  // Start the sequencer like pushing PLAY
}

catch(Exception ex) {
ex.printStackTrace();
}
}  // Close play
}

2、eclipse导出jar包可执行文件

在eclpse中找到你要导出的java程序 选中它















3、在cmd中检测运行是否jar文件成功



4、在windows中加入定时任务
点击开始按钮，依次选择打开“所有程序—附件—系统工具”，找到“任务计划程序”即可打开Win7系统的任务计划设置面板。也可以点击Win7开始按钮，在多功能搜索框中输入“任务计划”，直接从搜索结果中打开。
