Solutions for generating and printing word documents in Java

Users require the use of programs to generate standard word documents that can be printed and cannot be deformed. Many solutions have been used before, and the sacrifices are extremely fierce at customers' strict requirements.

It's okay for POI to read Word documents. It's not flattering to write documents. Complicated styles are hard to control. Imagine a 20-plus page. The word documents nested with many tables and images rely on POI to write code and output, it is worse for programmers than coal mining in Shanxi province. Besides, the document format is often changed.

It is okay to operate Excel on iText. It is also a nightmare for a large number of complicated words.

The output style through JSP is basically not up to standard, and printing is even worse.

Word supports XML format starting from 2003. It is easy to use XML.

The general idea is to first edit the word style with office2003 or 2007, then save it as xml, translate the xml into the FreeMarker template, and finally parse the FreeMarker template with java and output the Doc. It is tested that the word documents generated in this way fully comply with the office standards. Style and content control is very convenient, and printing is not distorted. The generated documents are exactly the same as the edited documents in the office.

See the actual results:

First, use office [Version 2003 or above, the following does not support xml format] to edit the document style. The red line in the figure is the part I want to output:

Save the edited document as XML

Use Firstobject free XML editor [use of Firstobject free XML editor can be found here] to mark the place where data needs to be filled in xml with FreeMarker. [for the syntax of FreeMarker, see here]
