我想从“FolderPath”列下的Excel工作表中读取并获取文件夹路径，并在名为“Documentum”的父文件夹下创建文件夹结构列表。我附上了样本excel数据，如下所示。我可以通过硬编码要创建的文件夹路径从下面的代码创建一个文件夹。对于Eg，在这种情况下，它是： / documentum。
FOLDERPATH
/documentum/folder1
/documentum/folder2
/documentum/folder3
/documentum/folder8/folder9
**
请提示，我如何在以下代码中添加此功能。我尝试使用excel POI但没有运气，因为我在POI中没有多少工作，对以下代码的任何样本修改或建议都有帮助。

您可以使用Apache POI库。如果您正在运行自己的脚本，则需要将其添加到类路径中;如果您正在执行documentum作业（由documentum JMS执行），则需要将其添加到java_methods目录中

我将在这里发布我的POI代码：
首先：
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
您可以从我的示例中提取我如何使用它：
我用过：
代码： rowStart = 1;意味着我逐行从数据行开始处理。 lastColumn = 4;意味着我有4列。
修复代码，如何找到你喜欢的。
// Create Workbook instance holding reference to .xlsx file
XSSFWorkbook workbook;
try
{
workbook = new XSSFWorkbook(file);
// Get first/desired sheet from the workbook
XSSFSheet sheet = workbook.getSheetAt(0);

int rowEnd = sheet.getLastRowNum();
for (int rowNum = rowStart; rowNum < rowEnd; rowNum++)
