JavaWeb项目音频资源播放解决方案

一、方式1:登陆系统后进行播放,即在浏览器端

需要在JSP页面编写相关代码

<div id="midea" style="display: none;">
	<object id='player' height='100' width='200' classid='CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6'>
		<param name='AutoStart' value='0' />
		<param name='Balance' value='0' />
		<param name='enabled' value='-1' />
		<param name='EnableContextMenu' value='-1' />
		<param name='url' value='${pageContext.request.contextPath}/player/bestduanxin.wav' />
		<param name='volume' value='100' />
		<param name='uiMode' value='mini' />
	</object>
</div>

在js脚本里调用

document.getElementById('player').controls.play();
setTimeout(stopPlayer,6000);
function stopPlayer(){
	document.getElementById('player').controls.stop();
}

  

二、方式2:不用登陆即可播放,即在服务器端

需在java后台编写相关代码

import java.applet.Applet;
import java.applet.AudioClip;
import java.net.URL;
import java.util.Timer;
import java.util.TimerTask;
import javax.servlet.http.HttpServletRequest;

public class AudioPlayer {
	public static void player(HttpServletRequest request){
		URL audioUrl=null;
		try {
			//项目URL根路径
			String path = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+request.getContextPath();
			//音频资源地址
			audioUrl = new URL(path+"/player/bestduanxin.wav");
			//创建音频播放类
			final AudioClip audioClass=Applet.newAudioClip(audioUrl);
			audioClass.loop();
			//new一个线程执行停止播放
		      TimerTask task = new TimerTask() {
				@Override
				public void run() {
					audioClass.stop();
				}
			};
			//new一个定时器,指定播放若干秒后执行停止播放
		    Timer timer = new Timer();
		    timer.schedule(task, GetPropertiesValue.getTimes()*GetPropertiesValue.getDuration());
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

  

附获取音频文件时长的方法

File file = new File(url.substring(0, url.indexOf("WEB-INF"))+"player/bestduanxin.wav");
Clip clip = AudioSystem.getClip(); AudioInputStream ais = AudioSystem.getAudioInputStream(file); clip.open(ais);
//得到的时间为微秒(μs),除以1000得到毫秒(ms)数 System.out.println(clip.getMicrosecondLength()/1000);
