java - 无法在 selenium 代码中使用 poi 在 excel 文件中写入输出

Question

我正在编写一段代码，从 excel 工作表 获取数据并对其运行 selenium 测试，并将输出写入不同的 excel 文件中。但我无法查看输出文件中的输出。我收到错误，因为 excel 在 java 代码后的 .xlsx 消息中发现了不可读的内容。

我还从 Excel 文档中读取输入，并将输出写入单独的 excel(.xls) 文档中。与您不同的是，我使用了 HSSFWorkbook，它只允许我的输出以 .xls 格式编写，但这不会影响实现。

我看到的显着区别是您在关闭文件之前编写工作簿，如下所示: 工作簿.write(fileOut); fileOut.flush(); fileOut.close();

这就是我的实现方式:

        HSSFWorkbook workbook = new HSSFWorkbook();
        String fileName = "excelDoc\\" +(new SimpleDateFormat("dd-MM-yy--hh-mm-ss").format(Calendar.getInstance().getTime()))+ ".xls"; //relative location of file + Time stamp based file name (.xls)
        System.out.println(fileName);       
        FileOutputStream  file1 = new FileOutputStream (new File(fileName));    
        HSSFSheet spreadSheet = workbook.createSheet("Result Document");
        HSSFRow row = spreadSheet.createRow((short) 0);
        HSSFCell cell;
        //Creating rows and filling them with data 
        cell = row.createCell(0);
        cell.setCellValue(new HSSFRichTextString("Test No"));
        cell = row.createCell(1);
        cell.setCellValue(new HSSFRichTextString("Test Result"));
        //Please see below and compare
        file1.close();  //Closing the file       
        FileOutputStream outFile =new FileOutputStream(new File(fileName));  //Creating new file
        workbook.write(outFile);   //printing the data in the new file
        outFile.close();           //closing the new file
        System.out.println("The Result are now printed in the excel sheet");
