下面给出的程序是用于提取MP3文件内容和元数据:
import java.io.File; import java.io.FileInputStream; import java.io.IOException; import org.apache.tika.exception.TikaException; import org.apache.tika.metadata.Metadata; import org.apache.tika.parser.ParseContext; import org.apache.tika.parser.mp3.LyricsHandler; import org.apache.tika.parser.mp3.Mp3Parser; import org.apache.tika.sax.BodyContentHandler; import org.xml.sax.SAXException; public class Mp3Parse { public static void main(final String[] args) throws Exception, IOException, SAXException, TikaException { //detecting the file type BodyContentHandler handler = new BodyContentHandler(); Metadata metadata = new Metadata(); FileInputStream inputstream = new FileInputStream(new File("example.mp3")); ParseContext pcontext = new ParseContext(); //Mp3 parser Mp3Parser Mp3Parser = new Mp3Parser(); Mp3Parser.parse(inputstream, handler, metadata, pcontext); LyricsHandler lyrics = new LyricsHandler(inputstream,handler); while(lyrics.hasLyrics()) { System.out.println(lyrics.toString()); } System.out.println("Contents of the document:" + handler.toString()); System.out.println("Metadata of the document:"); String[] metadataNames = metadata.names(); for(String name : metadataNames) { System.out.println(name + ": " + metadata.get(name)); } } }
保存上述代码保存为JpegParse.java,并通过使用下面的命令从命令提示编译:
javac Mp3Parse.java java Mp3Parse
在这里,我们传递一个example.mp3文件具有以下属性:
执行上述程序后,将得到下面的输出。
如果给定的文件有任何的歌词,我们的应用程序将捕获和显示,和输出。
输出:
