阅读更多关于 how create a Word document from a template or existing document with Java?

问题 I have a document template where some fields are static and others are dynamic. I need to replace some data (name, last name, salary) and generate the new file. What library do you recommend to do this? Is POI appropriate? I am working with Spring, Java EE6 and Oracle. 回答1: You can give Apache POI a try but the HWPF and XWPF part of POI which are required to manipulate word files are really complicated to use - you need to have at least a good understanding how a word file is structured!

So my question: Is there any library which supports both? 回答1: Aspose covers all of Microsofts formats, but it is not free and not open source. Regarding open source Java

Detecting hidden cells in excel using apache poi

阅读更多关于 Detecting hidden cells in excel using apache poi

问题 We are using apache poi 3.8 to parse excels. We need to be able to detect (and skip) hidden rows as they tend to contain junk data in our usecases. It would seem this should work: row.isFormatted() && row.getRowStyle().getHidden() But there never appears to be any row-level formatting (getRowStyle() always returns null). As a last resort we thought checking cell styles might work: for (int i = 0; i < row.getLastCellNum(); i++) { Cell cell = row.getCell(i); if (cell != null && cell
