通过 Apache POI 和 Java 网络应用程序读取 Excel，但显示错误为 "java.io.IOException: org/apache/commons/compress/archivers/zip/ZipFile"

Question

在 java 网络应用程序中，我需要读取 excel 文件的单元格。我在这里使用apachi poi。但它显示错误如下

java.io.IOException: org/apache/commons/compress/archivers/zip/ZipFile

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.*;
import java.util.Iterator;
import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.*;


public class importservlet extends HttpServlet { 

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {

    PrintWriter out=response.getWriter();        
    try{

      File file=new File("E:\Book1.xlsx");
      Workbook wb = WorkbookFactory.create(file);
      Sheet sheet = wb.getSheetAt(0);
      out.println(sheet.getRow(1).getCell(1).getCellType());
      wb.close();
      }
    catch(Exception e){
        out.println(e);
     }
    
     }

     }

我使用了以下 jar 文件

• poi-4.1.0

• poi-ooxml-4.1.0

• poi-ooxml-schemas-4.1.0

• xmlbeans-3.1.0

• commons-collections 4.4.3
