Java使用jacob将微软office中word、excel、ppt转成pdf
这篇文章主要为大家详细介绍了Java使用jacob将微软office中word、excel、ppt转成pdf，具有一定的参考价值，感兴趣的小伙伴们可以参考一下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：
<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
public void wps2pdf(string inputfile,string pdffile) {
file sfile = new file(inputfile);
file tfile = new file(pdffile);
activexcomponent wps = null;
try {
comthread.initsta();
wps = new activexcomponent("wps.application");
activexcomponent doc = wps.invokegetcomponent("documents").invokegetcomponent("open", new variant(sfile.getabsolutepath()));
doc.invoke("exportpdf", new variant(tfile.getabsolutepath()));
doc.invoke("close");
doc.saferelease();
} catch (exception e) {
system.out.println(e.getmessage());
} finally {
if (wps != null) {
wps.invoke("terminate");
wps.saferelease();
}
comthread.release();
}
}
