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

1 2 3 4 5 6 7 8 9 10 11

<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");<br>Clip clip = AudioSystem.getClip(); AudioInputStream ais = AudioSystem.getAudioInputStream(file); clip.open(ais);<br>//得到的时间为微秒（μs），除以1000得到毫秒（ms）数 System.out.println(clip.getMicrosecondLength()/1000);
