apache-tika - 如何使用TIka读取大文件？

Question

我正在使用 Tika 解析大型 pdf 和 word 文档，但我收到以下错误消息。

Your document contained more than 100000 characters, and so your requested limit has been reached. To receive the full text of the document, increase your limit. (Text up to the limit is however available).

如何提高限​​制？

Answer 1

假设您基本上遵循 Tika example for extracting to plain text ，那么您需要做的就是 create your BodyContentHandler with a write limit of -1禁用写入限制，如 javadocs 中所述

您的代码将类似于 ( inspired by the example ):

BodyContentHandler handler = new BodyContentHandler(-1);

InputStream stream = ContentHandlerExample.class.getResourceAsStream("test.doc");
AutoDetectParser parser = new AutoDetectParser();
Metadata metadata = new Metadata();
try {
    parser.parse(stream, handler, metadata);
    return handler.toString();
} finally {
    stream.close();
}
