与在 java 中使用 Apache POI 阅读 Excel 相关的问题
Issue related to Reading Excel using Apache POI in java
我正在尝试创建 2007 年的 excel 文件。
从其他文件创建 Excel 的方案。
输入文件：- InputFile.xlsx with One Sheet
计算文件：- Model.xlsx 有四个 sheets
计算文件说明:- 1) 第一个 Sheet 是输入文件
2) 第二个 sheet 是输出 3) 第三个和第四个 Sheet 是计算 sheets.
在 Java 中使用 Apache POI 我正在阅读 Excel 文件。在我正在读取文件的一个函数中，获取输入文件 InputFiles.xlsx
在第二个函数中，我在 model.xlsx 文件中合并了两个 sheet。 i.e.in Model.xlsx 的第一个 sheet 合并 InputFile.xlsx
的第一个 sheet
在第三个函数中，我正在读取输出，这会影响写入 model.xlsx 并读取它。

问题是：- 在 java 中使用 apache poi 读取第二个 sheet 时，如果 Model.xlsx 包含更新数据，它会读取以前的数据而不是 calculation.even 之后的更新数据java 只读以前的 data.This 很奇怪找我任何解决方案。
请帮助我。
谢谢。

问题是：- 在 java 中使用 apache poi 读取第二个 sheet 时，如果 Model.xlsx 包含更新数据，它会读取以前的数据而不是 calculation.even 之后的更新数据java 只读以前的 data.This 很奇怪找我任何解决方案。
请帮助我。
谢谢。
