有人可以帮我解决一下吗？
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，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"));
}
无法设置它，因为您不与 WriteOutContentHandler 交互。顺便说一句，它默认设置为 -1，这意味着没有限制。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);
}
最佳答案
您一定忽略了内容处理程序具有带写入限制的构造函数。
ContentHandler textHandler = new BodyContentHandler(int writeLimit);
