TIKA提取MP3檔案

下面給出的程式是用於提取MP3檔案內容和後設資料：

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));
      }
   }
}

儲存上述程式碼儲存為JpegParse.java，並通過使用下面的命令從命令提示編譯：

javac Mp3Parse.java
java Mp3Parse 

在這裡，我們傳遞一個example.mp3檔案具有以下屬性：

執行上述程式後，將得到下面的輸出。

如果給定的檔案有任何的歌詞，我們的應用程式將捕獲和顯示，和輸出。
