我的整合，java 經過aspose轉PDF ，支持各類格式 JPG ，TXT， PPT， EXCEL， DOC 免費開箱即用版

1.  導入jar包

（linux服務器轉出來的PDF會有中文框框亂碼，經過下載字體能解決，網上有解決辦法）

itextpdf-5.5.6.jar

aspose-words-18.6-jdk16.jar

aspose.slides-15.9.0.jar

aspose-cells-8.5.2.jar

itext-asian-5.2.0.jar

連接：https://pan.baidu.com/s/1DRAnRxT037hibWey5uJ_AA 提取碼：f3q1  

2.配置文件   XML

放在WEB-INF  下 classes目錄下  ，配置代碼：
