java通过aspose实现文档间格式转换
aspose简述
Aspose.Total是Aspose公司旗下的最全的一套office文档管理方案，主要提供.net跟java两个开发语言的控件套包，通过它，我们可以有计划地操纵一些商业中最流行的文件格式：Word, Excel, PowerPoint, Project,等office文档以及PDF文档。如需下载aspose.total官方网址：https://downloads.aspose.com/total/
- 以下这是基于java语言版的，如果需要.net语言的可以去官网参考学习。

以上测试基本通过，转换时如是PDF转Word如不需图片之类用PDFbox包即可解决，且效果不错，有其他参数参与的用aspose.Words效果较好。使用转换图片类型的PDF文件效果较差，不推荐。
