Tika判断数据类型（可准确判断）版权声明

try (InputStream is = theInputStream;
        BufferedInputStream bis = new BufferedInputStream(is);) {
    AutoDetectParser parser = new AutoDetectParser();
    Detector detector = parser.getDetector();
    Metadata md = new Metadata();
    md.add(Metadata.RESOURCE_NAME_KEY, theFileName);
    MediaType mediaType = detector.detect(bis, md);
    return mediaType.toString();//Return是文件类型
}
