IOException: org.apache.poi.xssf.usermodel.XSSFWorkbookFactory not found - check if poi-ooxml-*.jar is on the classpath.

这个错误是由于缺少poi-ooxml包所致。您需要将该jar包添加到您的项目中。可以在https://poi.apache.org/download.html下载poi-ooxml-*.jar并将其放入您的classpath中。如果您在使用Maven或Gradle等依赖管理工具,则可以将其添加到您的依赖项中。

你这个代码要使用什么版本的poi库import java.io.File;import java.io.FileInputStream;import java.io.FileOutputStream;import java.io.IOException;import org.apache.poi.ss.usermodel.Cell;import org.apache.poi.ss.usermodel.Row;import org.apache.poi.ss.usermodel.Sheet;import org.apache.poi.ss.usermodel.Workbook;import org.apache.poi.xssf.usermodel.XSSFWorkbook;public class ExcelModifier { public static void main(String[] args) { try { // 打开 Excel 文件 FileInputStream file = new FileInputStream(new File("path/to/excel/file.xlsx")); // 创建工作簿对象 Workbook workbook = new XSSFWorkbook(file); // 获取第一个工作表 Sheet sheet = workbook.getSheetAt(0); // 获取要修改的单元格 Row row = sheet.getRow(0); Cell cell = row.getCell(0); // 修改单元格的值 cell.setCellValue("New Value"); // 保存修改后的 Excel 文件 FileOutputStream outFile = new FileOutputStream(new File("path/to/excel/file.xlsx")); workbook.write(outFile); outFile.close(); System.out.println("Excel 文件修改成功!"); } catch (IOException e) { e.printStackTrace(); } }}
这段代码使用的是Apache POI的XSSF版本,即针对Excel 2007及以上版本的XML格式的Workbook。所以需要在项目中引入以下Maven依赖或手动导入相应jar包:
```xml
<dependency>
<groupId>org.apache.poi</groupId>
<artifactId>poi-ooxml</artifactId>
<version>4.1.2</version>
</dependency>
```
或者手动下载jar包,然后添加到项目的classpath中。
