TIKA提取MP3文件

下面給出的程序是用於提取MP3文件內容和元數據：

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)); } } }

保存上述代碼保存爲JpegParse.java，並通過使用下面的命令從命令提示編譯：

javac Mp3Parse.java
java Mp3Parse

在這裏，我們傳遞一個example.mp3文件具有以下屬性：

執行上述程序後，將得到下面的輸出。

如果給定的文件有任何的歌詞，我們的應用程序將捕獲和顯示，和輸出。
