解析文档时的Apache Tika和字符限制

Question

可以请任何人帮我解决一下吗？

它可以这样做

   Tika tika = new Tika();
   tika.setMaxStringLength(10*1024*1024);

但如果你不直接使用Tika,就像这样:

ContentHandler textHandler = new BodyContentHandler();
Metadata metadata = new Metadata();
Parser parser = new AutoDetectParser();

ParseContext ps = new ParseContext();
for (InputStream is : getInputStreams()) {
    parser.parse(is, textHandler, metadata, ps);
    is.close();
    System.out.println("Title: " + metadata.get("title"));
    System.out.println("Author: " + metadata.get("Author"));
}

没有办法设置它,因为你没有与之交互WriteOutContentHandler.顺便说一下,它-1默认设置为没有限制.但由此产生的限制是100000个字符.

/**
 * The maximum number of characters to write to the character stream.
 * Set to -1 for no limit.
 */
private final int writeLimit;

/**
 * Number of characters written so far.
 */
private int writeCount = 0;

private WriteOutContentHandler(Writer writer, int writeLimit) {
    this.writer = writer;
    this.writeLimit = writeLimit;
}

/**
 * Creates a content handler that writes character events to
 * the given writer.
 *
 * @param writer writer
 */
public WriteOutContentHandler(Writer writer) {
    this(writer, -1);
}

您一定忽略了内容处理程序具有writelimit的构造函数.

ContentHandler textHandler = new BodyContentHandler(int writeLimit);
