">

File source =new File('d:\\testmp3'); 

Encoder encoder = new Encoder();

MultimediaInfo m = encodergetInfo(source);

long ls = mgetDuration();

duration = ls/1000;

Systemoutprintln("此视频时长为:"+ls/60000+"分"+(ls/1000-ls/6000060)+"秒！");

若用的是springmvc框架上传文件

Multipart>

while(iterhasNext()){

MultipartFile file = multiRequestgetFile(iternext());

String fileOldName = filegetOriginalFilename();

long duration = 0;//音频长度，秒

CommonsMultipartFile cf= (CommonsMultipartFile)file;

DiskFileItem fi = (DiskFileItem)cfgetFileItem();

File source = figetStoreLocation();

Encoder encoder = new Encoder();

MultimediaInfo m = encodergetInfo(source);

long ls = mgetDuration();

duration = ls/1000;}

String cmd="rundll32 urldll FileProtocolHandler file://c:\爱你爱到骨头里mp3";

Process p = RuntimegetRuntime()exec(cmd);

File file = new File("G:\\8mp3");

long total = 0;

try {

AudioFileFormat aff = AudioSystemgetAudioFileFormat(file);

Map props = affproperties();

if (propscontainsKey("duration"))

total = (long) Mathround((((Long) propsget("duration"))

longValue())/1000); Systemoutprintln(total);

} catch (UnsupportedAudioFileException e) {

// TODO Auto-generated catch block

eprintStackTrace();

} catch (IOException e) {

// TODO Auto-generated catch block

eprintStackTrace();

}
