环境准备

1、Office（wps无法转换）
2、window服务
3、pom依赖

        <!-- PDF-jacob --><dependency><groupId>net.sf.jacob-project</groupId><artifactId>jacob</artifactId><version>1.14.3</version></dependency><!-- PDF-ITEXT --><dependency><groupId>com.itextpdf</groupId><artifactId>itextpdf</artifactId><version>5.3.4</version></dependency><dependency><groupId>com.itextpdf</groupId><artifactId>itext-asian</artifactId><version>5.2.0</version></dependency>

4、2个配置文件
jacob-1.14.3-x64.dll（对应jacob依赖版本）
放置于jdk对应bin目录下：

msyh.ttf (写水印的字体)
放置于对应目录下（因为将文件放置于项目中resource下，在打包时会把该文件编译，会造成文件损坏，所以我这边用的是绝对路径）

File sourceFile = FileUtil.file("D://root/test.xlsx");

//根据具体转换调用具体的转换方法，例如：
PDFHelper.xls2pdf(sourceFile.getAbsolutePath(), targetFile.getAbsolutePath());
