aspose word转pdf

关于word转pdf因为项目需要,网上找了很多的教程发现在windows上可以转换，linux上转换不成功。 以下为linux下 docker启动springboot项目转换的过程。

• 1.将windows下面的字体复制到linux目录下 windows目录为C:\Users\JO-09\AppData\Local\Microsoft\Windows\Fonts 如果word字体为楷体就找到simkai.ttf复制到linux的目录下，我这里复制到/tmp/sign/fonts
• 2.docker命令添加项目启动时的文件映射 -v /tmp/sign/fonts:/usr/share/fonts/
• 3.maven的导包

• 4.resource里面增加一个文件license.xml

6.windows测试

public static void main(String[] args) throws FileNotFoundException {
    WordToPdfUtils utils = WordToPdfUtils.getUtils();
   // utils.docxToPdf(new FileInputStream("D:/桌面/卷内文件1002247741864148992.docx"), new FileOutputStream("D:/桌面/test.pdf"));
    utils.docxToPdf(new FileInputStream("D:\jieou\projectCode\letter-open-api\letter-open-system\src\main\resources\jh522nc.docx") ,
            new FileOutputStream("D:\jieou\projectCode\letter-open-api\letter-open-system\src\main\resources\jh522nc222.pdf"));
}

7.正常打包部署到docker 8.可能遇到的问题：a.aspose.jar下载不了。b.乱码问题（乱码大概率是字体没有导入到linux导致的）
