将office文件转化为html格式或者pdf格式
在转换之前，需要启动openOffice的服务：在openOffice目录下的命令窗口中执行soffice -headless -accept=”socket,host=127.0.0.1,port=8100;urp;” -nofirststartwizard即可启动
不知道如何启动的参照我的另外一篇文章
我用的maven工程，先要引入依赖，加到pom.xml中
<!-- https://mvnrepository.com/artifact/com.artofsolving/jodconverter -->
<dependency>
<groupId>com.artofsolving</groupId>
<artifactId>jodconverter</artifactId>
<version>2.2.1</version>
</dependency>
在D盘的这个目录下面加入这些个office文件和openOffice文件夹
话不多说，直接上代码。

执行代码，命令行没有报错
查看转换出来的文件doc转的html
ppt转的html
xls转的html
转换pdf只要把上面的注释代码打开即可，测试过是可以转换成pdf的，
docx的暂时不能转换，我查了一下说是jodconverter的2.2版本的好使。
大家还有什么问题可以私信于我。
