我在文件夹C：\ DemoFilesExcel \ demo1.xlsx和C：\ DemoFilesExcel \ demo2.xlsx中有两个xlsx文件。
我想创建一个新的xlsx C：\ DemoFilesExcel \ merged.xlsx，它将这两个文件作为merged.xlsx工作簿中的两个工作表。
这是在java中使用apache POI完成的。任何想法怎么做
//Open the first excel file.
Workbook SourceBook1 = new Workbook("F:\\Downloads\\charts.xlsx");
//Define the second source book.
//Open the second excel file.
Workbook SourceBook2 = new Workbook("F:\\Downloads\\picture.xlsx");
//Combining the two workbooks
SourceBook1.combine(SourceBook2);
//Save the target book file.
SourceBook1.save("F:\\Downloads\\combined.xlsx");
http://www.aspose.com/docs/display/cellsjava/Combine+Multiple+Workbooks+into+a+Single+Workbook
下面这段代码可用于将两个excel文件合并为两个工作簿中的两个工作簿。这将复制具有相同结构的两个excel文件。
它对我有用。

我最初的想法是使用XSSFWorkbook的cloneSheet方法来完成这个技巧，我成功地复制了关系和绘图但却无法复制数据本身。为什么？因为XSSFSheet的方法写入和读取受到保护，我确实通过扩展它并使两个方法写入和读取公共来提出我自己的XSSFSheet版本，但这意味着我将不得不使用XSSFSheet替换来复制和编辑每个源文件它与我的XSSFSheet版本相比，意味着太多的编码，我没有那个项目的时间。
这个问题的原始答案发布在：
How to copy a sheet between Excel workbooks in Java
但是，我的项目要求不同，所以我即兴创作了答案。
我添加了一个名为combine的方法，它接受目标工作簿和源工作簿。
这些方法遍历源工作簿中的所有工作表，并将它们添加到目标工作簿。原来的答案缺乏关系和绘画的复制。
我还要复制的工作簿缺少Footer，neede Gridlines要关闭，并且适合页面。所以这是我的解决方案：
