Java使用jacob将微软office中word、excel、ppt转成pdf

时间:2018-12-20 09:33:28 编辑:猪哥 来源:转载

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:


 com.jacob
 jacob
 1.7
 system
 ${basedir}/../fileConvertApp/src/main/webapp/WEB-INF/lib/jacob.jar

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();
  } 
 }
