本文章向大家介绍如何在Java中使用jacob将word转换成pdf,主要包括如何在Java中使用jacob将word转换成pdf的使用实例、应用技巧、基本知识点总结和需要注意事项,具有一定的参考价值,需要的朋友可以参考一下。
Java主要应用于:1. web开发;2. Android开发;3. 客户端开发;4. 网页开发;5. 企业级应用开发;6. Java大数据开发;7.游戏开发等。
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();
}
}
