本文实例为大家分享了java使用jacob将微软office文档转成pdf的具体代码，供大家参考，具体内容如下
在使用jacb前，我们需要去下载 jacob.jar 和 jacob-1.18-x64.dll
其次，我们需要将jacob-1.18-x64.dll放入到jdk的bin目录下才可以使用
第三，使用jacb之前，我们需要确保office能正常使用
如果你现在使用的是maven工程，那么不好意思，现在还没有发布正式的jacb资源文件，我们需要自定的maven依赖，如下：
|
1 2 3 4 5 6 7 |
<dependency> <groupid>com.jacob</groupid> <artifactid>jacob</artifactid> <version> 1.7 </version> <scope>system</scope> <systempath>${basedir}/fileconvertapp/src/main/webapp/web-inf/lib/jacob.jar</systempath> </dependency> |
然后需要注意的是jar的地址，需要根据自己的情况修改
接下来我们贴一下具体使用的代码片段

根据自己的调试，试验一下吧。
另外还有一段wps转pdf，也贴一下，供大家参考一下
