• 注意版本号，不然会出问题

java demo

@Test
public void test() throws Exception {
    InputStream inputStream = Files.newInputStream(Paths.get("text.zip"));

    BodyContentHandler contentHandler = new BodyContentHandler(-1);
    Metadata metadata = new Metadata();
    ParseContext parseContext = new ParseContext();

    new AutoDetectParser()
            .parse(inputStream, contentHandler, metadata, parseContext);

	// 提取出来的内容
    System.out.println(contentHandler);
    System.out.println("-------------------------------------------");
    // 元数据信息
    String[] names = metadata.names();
    for (String name : names) {
        System.out.println(name + ":" + metadata.get(name));
    }
}
