      //Assume that boy.jpg is in your current directory
      File file=new File("E:\\上海项目测试\\metadata\\boy.jpg");

      //Parser method parameters

      BodyContentHandler handler = new BodyContentHandler();
      Metadata metadata = new Metadata();
      FileInputStream inputstream = new FileInputStream(file);

      parser.parse(inputstream, handler, metadata, context);
      System.out.println(handler.toString());

      //getting the list of all meta data elements 
      String[] metadataNames = metadata.names();

      for(String name : metadataNames) {                
         System.out.println(name + ": " + metadata.get(name));
      }
   }
