问题 I am using the 3.10 Version of POI. Problem I am running into is that I am creating a xls,xlsx file. All looks good when writing the file. It is about 2MB.

问题 Consider that I've a excel sheet in below format: person age Foo 29 Bar 27 Now I want to read these values (using POI HSSF) and have to process them. What's the best way to do that? Note that I do not have a Object Person in my application, becasue the values that may come in excel sheet is arbitrary (i.e. it may not be the person name and age).

问题 Using: XWPFDocument document = new XWPFDocument(); How do I assign it so it doesn't overwrite the file if it already exists? 回答1: The following will create a brand new, empty XWPF Word Document to work with: XWPFDocument document = new XWPFDocument(); Whereas this will open up an existing one for editing: XWPFDocument document = new XWPFDocument(OPCPackage.open("MyFile.docx")); Or if you have an InputStream rather than a file: XWPFDocument document = new XWPFDocument(inputStream); 来源： https:/
