TIKA - Extracting mp3 Files

以下是用于从 mp3 文件中提取内容和元数据的程序 −

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));
      }
   }
}

将上述代码保存为 JpegParse.java ，并使用以下命令从命令提示符编译该代码 −

javac Mp3Parse.java
java Mp3Parse

Example.mp3 文件具有以下属性 −
