【问题描述】：
我想从 "FolderPath" 列下的 Excel 工作表中读取和获取我的文件夹路径，并在名为 "Documentum" 的父文件夹下创建一个文件夹结构列表>。我附上了如下示例 excel 数据。我可以通过硬编码要创建的文件夹路径，从以下代码创建一个文件夹。例如，在这种情况下它是：/documentum.
文件夹路径
/documentum/folder1
/documentum/folder2
/documentum/folder3
/documentum/folder8/folder9
**
请建议，如何在下面的代码中添加此功能。我尝试使用 excel POI，但运气不佳，因为我在 POI 中工作不多，对以下代码的任何示例修改或建议都会有所帮助。

听起来您在问如何从 Excel 中提取数据，但您已经知道如何执行 Documentum 部分（从路径创建文件夹）。那是对的吗？在这种情况下，将其标记为 Excel 或 Java 问题而不是 Documentum 可能会更好。
-
是的，你是对的，我想在这里了解如何从 excel 中读取路径，迭代 excel 表中的列以获取文件夹路径并在 documentum 中创建文件夹。目前我可以在代码中创建硬编码的文件夹“/documentum”。任何关于在documentum中创建文件夹的excel读写建议都会有所帮助。
