java利用Freemark生成docx格式附件

xiaoxiao2023-10-04 140

1、首先去官网下载freemarker对应的jar包，我这边用的是这个架包 -- freemarker-2.3.18.jar。

2、然后新建一个document.docx 的world文件，新建后把要替换的地方放占位符如“${userName}”。

3、用你本地安装的解压工具打开压缩包（.docx可以看作是个压缩包），在word目录下，取出document.xml文件。

4、用notepad++打开，并且格式化xml,然后你的需求编辑（至于你要编辑成什么样得格式，网上可以找到）。

5、把你本地的document.docx和解压取出来编辑好的document.xml文件，相互替换后缀

（PS：把document.docx替换为document.xml,把document.xml替换为document.docx）。

不说那么多了上Code了.。
