java OpenOffice officetopdf
最近项目需要实现下载Office文档时自动转成PDF文档,以下代码支持2003及2007版的Word,PPT,Excel转换,并支持自定义添加水印、页眉、页脚
实现需要事先安装OpenOffice(我这里安装的是OpenOffice 4)
OpenOffice 下载: http://www.openoffice.org/
JodConverter 下载地址 http://sourceforge.net/projects/jodconverter/files/JODConverter
需要代码正常运行还需要其他Jar包(见附件)
Java代码:
