org.apache.tika.exception.TikaException：无法关闭临时资源

问题描述

我正在Windows 10 jre 1.8.0_241上使用Apache Tika，并且已经使用ant导入了 Tika 1.24.1 。 我有以下代码从PDF中提取内容：

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;

import org.apache.tika.Tika;
import org.apache.tika.exception.TikaException;
import org.apache.tika.metadata.Metadata;
import org.apache.tika.metadata.TikaCoreProperties;
import org.xml.sax.SAXException;

public class TikaExtraction {
    
   public static void main(final String[] args) throws IOException,TikaException {

      //Assume sample.txt is in your current directory              
      File file = new File("C:\\Users\\myPC\\Desktop\\testPDF.pdf");
      
      //Instantiating Tika facade class
      Tika tika = new Tika();
      String filecontent = tika.parseToString(file);
      System.out.println("Extracted Content: " + filecontent);
      
   }         
}

尝试从PDF提取内容时，出现以下异常：

我经历过TikaException: Failed to close temporary resource - how to fix?，但这是TesseractOCRParser的问题，而AutoDetectParser也遇到了同样的问题。 tmp文件位于Temp文件夹中，并且该文件似乎没有正确的解析内容。也没有冲突的罐子。任何有关如何解决该异常的见解将不胜感激！
