使用OpenNTF POI从Excel中获取值，但row.getCellType（）不再起作用

Question

我正在使用UpdateSite在Domino 10服务器上使用OpenNTF的最新POI版本

https://poi4xpages.openntf.org/

我的代码在Excel中读取单元格值

由于某种原因，rowdata.getCell（0）.getCellType（）方法不再起作用，并且在运行时会产生错误，因此我无法检查单元格包含的值的类型。

方法getStringCellValue（）和getNumericCellValue（）仅在Excel单元格中的值属于该类型时才有效，即，如果我有一个包含100的单元格，则它始终是一个数字。

在我的列中，我同时拥有100和100a，如果我将100a与getNumericCellValue（）一起使用，则会产生错误。

hsCurrent.put("FILE", inputFile);
Workbook wb = ioAction.run(null, hsCurrent);
worksheet = wb.getSheetAt(0);
rowdata = worksheet.getRow(1);
kod = rowdata.getCell(0).getStringCellValue();
price = rowdata.getCell(3).getNumericCellValue();

由于getCellType（）无法正常工作，我需要找到另一种方法来处理所收到的错误，如何在Java中做到这一点。

此外，如果您知道getCellType（）为何存在问题，请告诉我。

还请注意，所有这些方法都会检查excel中单元格的value，not它是哪种类型的单元格]

让我知道是否需要提供更多信息
