Apache Tika：从归档文件中删除文件名和MIME类型

Question

我希望Tika只输出文件名和文件的MIME类型。我用RecursiveParserWrapperHandler找到了一些解决方案，但问题是BodyContentHandler总是试图解析整个文件，并将文本放在正文内容中。在我的例子中，我只需要映射(fileName、MIMEType)作为返回结果，而不需要解析整个文件。我怎么能那么做？

 static public List<Metadata> recursiveParserWrapperExample() throws IOException,
        SAXException, TikaException {
    Parser p = new AutoDetectParser();

    ContentHandlerFactory factory = new BasicContentHandlerFactory(
            BasicContentHandlerFactory.HANDLER_TYPE.HTML, -1);
    RecursiveParserWrapper wrapper = new RecursiveParserWrapper(p);
    Metadata metadata = new Metadata();
    metadata.set(TikaCoreProperties.ORIGINAL_RESOURCE_NAME, "test.rar");
    ParseContext context = new ParseContext();
    RecursiveParserWrapperHandler handler = new RecursiveParserWrapperHandler(factory, -1);
    try (InputStream stream = new FileInputStream(new File("C:\\Users\\alex\\home\\projects\\self\\zip\\test.rar"))) {
        wrapper.parse(stream, handler, metadata, context);
    }
    return handler.getMetadataList();
}

我找到了解决方案，它是如此简单，只是改变

    ContentHandlerFactory factory = new BasicContentHandlerFactory(
        BasicContentHandlerFactory.HANDLER_TYPE.HTML, -1);

到

    ContentHandlerFactory factory = new BasicContentHandlerFactory(
        BasicContentHandlerFactory.HANDLER_TYPE.IGNORE, -1);

就这样，现在处理程序将只从文件返回metdata。
