#docx4j介绍

docx4j是一个用于创建和操作Microsoft Open XML (Word docx, Powerpoint pptx, 和 Excel xlsx)文件的Java类库。

#开发环境

笔记仅供参考,具体开发环境可能存在版本差异。

OS:Windows 10

JDK:SUN 1.8

Eclipse:4.5[STS Spring定制版]

Maven:3.3.9

#使用介绍

这个问题之前是用卓正office解决的文档合成，我个人不是很满意效果。现在找到了新的方案感觉挺不错的，所以只是演示合成。我感觉poi也是可以的，但是我并没发现有合并文档的方法。也许是我不够深入吧。

#测试结果

图片文字样式都可以合成，唯独插入的表单是个合成的时候位置不对。有待研究用法。
