Question

使用以下代码从Excel工作表中检索数据：

import java.io.FileInputStream;
import java.io.IOException;
import org.apache.poi.xssf.usermodel.XSSFCell;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
    public class poi_excel {
        public static void main(String[] args) throws IOException {
        // TODO Auto-generated method stub
        FileInputStream fis =new FileInputStream("F:\\Selenium Using Web Driver\\Plugins\\HEC_login.xlsx");
        XSSFWorkbook wb=new XSSFWorkbook(fis);
        XSSFSheet sheet=wb.getSheet("script");
        XSSFRow row=sheet.getRow(1);
        XSSFCell cell=row.getCell(1);
        String value = cell.getStringCellValue();
        System.out.println(value);
                }    }

发生以下错误

WARNING: An illegal reflective access operation has occurred

请提供解决方案以解决此问题。

Answer 1

XSSFSheet sheet=wb.getSheet("script.type");

输入文件类型（.xlsx或其他）代替type，然后重试。

编辑：同时检查文件是否在工作目录中。

Apache POI - Excel（poi-bin-3.17）无法处理Selenium获取警告错误？
