aspose office转pdf

office文件转pdf
今天有点上火，直接上货采用方式aspose(破解版)，非商业版
springboot
依赖包下载（所需依赖不能通过pom下载需要手动下载以后添加到项目）
添加maven依赖

一切准备好以后在linux时生成需要有windows字体否则可能会出现pdf乱码问题
将字体导入到linux后执行
sudo fc-cache -fv ##更新字体
fc-list :lang=zh ##查看中文字体
烧脑的一天结束了！！！！！！！！！！！！！！希望能够帮助各位看官！！！
好了,暂时未处理统计数据可能出现负值的情况，如有需要请联系578616864进行交流
