本文介绍了解析文档时的Apache Tika和字符限制的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
可以请任何人帮我解决一下吗?
Could please anybody help me to sort it out?
可以这样做
Tika tika = new Tika();
tika.setMaxStringLength(10*1024*1024);
但是如果你不直接使用Tika,就像这样:
But if you don't use Tika directly, like this:
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,因为你不与之交互 WriteOutContentHandler
。顺便说一下,它默认设置为 -1
,这意味着没有限制。但是由此产生的限制是100000个字符。
There is no way to set it up, because you don't interact with the WriteOutContentHandler
. Btw it is set to -1
by default which means no restrictions. But the resulting restriction is 100000 characters.
/**
* 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);
}
推荐答案
你一定忽略了content handler有一个带有writelimit的构造函数。
You must have overlooked that the content handler has constructor with writelimit.
ContentHandler textHandler = new BodyContentHandler(int writeLimit);
