doc或docx(word)或image类型文件批量转PDF脚本
doc或docx(word)或image类型文件批量转PDF脚本
1.实际生产环境中遇到文件展示只能适配PDF版本的文件,奈何一万个文件有七千个都是word或者image类型的,由此搞个脚本批量转换下上传至OSS,为前端提供数据支撑。
2.环境准备,这里使用的是aspose-words-18.6-jdk16-crack.jar工具包,资源包就不提供了,网上百度一下即可。
3.javaMaven项目,jdk1.8.maven3.6
4.使用aspose-words-18.6-jdk16-crack.jar工具包会产生水印,需要配置resources下去除水印配置:

7.上述就是word或者image类型的批量脚本,可以在工具类中单元测试之后在使用批量逻辑代码。
