Apache poi is an open-source library of the Apache Software Foundation. Poi provides APIs for Java programs to read and write Microsoft Office files.

Perhaps the hssf name is a bit funny. In essence, it is a very seri

The overall realization idea is:Every time you query out 2w data and write to a temporary fileThen write these files into an Excel, or compress the files into a zip file, and then provide the zip file to the download (Zip packaging is used here because it can also be zip-packaged on Linux).This

Reason:Java's encoding of text is based on Unicode, so if you use Zipinputstream and Zipoutputstream to handle compression and decompression, and you run into a Chinese filename or path, then of course it's Unicode. However, the current compression and decompression software, such as WinZip, does not support Unicode, and it does not handle a file that is encoded in Unicode with a filename. So how do you make the compression files that WinZip can handle? There are two ways of doing this: one is t

Reason:Java encoding of the text is based on Unicode, so if Zipinputstream and Zipoutputstream to deal with the compression and decompression work, encountered in the Chinese file name or path, it is of course the Unicode to deal with ROM. However, now on the market compression and decompression software, such as WinZip, but does not support Unicode, a file name in Unicode-encoded file, it will not be processed. So how do you make the compression file that WinZip can handle? There are two ways o

Java uses POI to export data in ExcelThe Export and Import functions of data need to be used in recent projects. My colleagues and I are responsible for the export function, which is relatively simple. As for the comrades who want to see the import, I do not have it for the moment, so don't waste time on this article. However, the import function will be added later.When I see some blogs that reference various util toolkit, I can simply use apache

The poi component of Apache is a powerful API used to operate Microsoft office suites in Java. It supports Word, Excel, and powperpoint.

If the number of elements of each iterator is inconsistent, the returned list is the same length as the shortest object, and with the * operator, the tuple can be decompressed as a list.Grammarzip([iterable, ...])Parameters ITERABL--
