JAVA编程获取音频时长

具体代码如下：

File source =new File('C:/Users/Qiang/Desktop/Alone.mp3'); Encoder encoder = new Encoder();MultimediaInfo m = encoder.getInfo(source);long ls = m.getDuration();duration = ls/1000;System.out.println("time is:"+ls/60000+"min"+(ls/1000-ls/60000*60)+"sec");

使用SpringMVC框架上载文件，代码如下：

MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest)request;  Iterator<String> iter = multiRequest.getFileNames(); while(iter.hasNext()){          MultipartFile file = multiRequest.getFile(iter.next());          String fileOldName = file.getOriginalFilename();          long duration = 0;          CommonsMultipartFile cf= (CommonsMultipartFile)file;          DiskFileItem fi = (DiskFileItem)cf.getFileItem();          File source = fi.getStoreLocation();           Encoder encoder = new Encoder();          MultimediaInfo m = encoder.getInfo(source);          long ls = m.getDuration();          duration = ls/1000;}

所用的jar包：jave-1.0.2.jar，自行百度下载导入即可。
