apache poi-将Pojo列表转换为HSSFSheet的任何方法？

Question

Would be a pretty awesome feature in apache POI HSSFBeanHelper.toHssfSheet(HSSFWorkbook workbook, List<Object> obj) that would create a HSSFSheet from a list of Pojo.

Does it exist?

Answer 1

There are two API's that both sit on top of POI that provide kind-of the functionality you suggest:

• http://jxls.sourceforge.net/
• http://jett.sourceforge.net/

Both libraries are extremely similar, on the JETT website there's even a handy comparison table

Both take an Excel file as a template and will fill it up with variables you provide (and these variables can include one or more lists of objects). So, creating a spreadsheet from a list of POJO's is very simple, but it's equally easy to provide Excel formulas that will be executed using the filled in data, and even charts and for me that's the real power of these libraries.
