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

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

本文实例http://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

import java.io.File;

import org.apache.log4j.Logger;

import com.jacob.activeX.ActiveXComponent;

import com.jacob.com.Dispatch;

import com.jacob.com.Variant;

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();

}

}
