首先我自己的环境是windows xp ,office2007 ,jdk1.5;
1.先下载office2007 能另存为pdf的插件 SaveAsPDFandXPS.exe 安装。(纠结了好久才知道要安装这个插件，否则无法调用SaveAs方法)2.下载jacob，位置如下：jacob.jar 放在 E:\jdk1.5.0_14\lib
jacob.dll 放在 E:\jdk1.5.0_14\bin 源代码如下：package test.jacob;import java.io.File;import com.jacob.activeX.ActiveXComponent;import com.jacob.com.ComThread;import com.jacob.com.Dispatch;import com.jacob.com.Variant;public class Test { static final int wdFormatPDF = 17;// PDF 格式 public void wordToPDF(String sfileName,String toFileName){ System.out.println("启动Word..."); long start = System.currentTimeMillis(); ActiveXComponent app = null; Dispatch doc = null; try { app = new ActiveXComponent("Word.Application"); app.setProperty("Visible", new Variant(false)); Dispatch docs = app.getProperty("Documents").toDispatch(); // doc = Dispatch.call(docs, "Open" , sourceFile).toDispatch(); doc = Dispatch.invoke(docs,"Open",Dispatch.Method,new Object[] { sfileName, new Variant(false),new Variant(true) }, new int[1]).toDispatch(); System.out.println("打开文档..." + sfileName); System.out.println("转换文档到PDF..." + toFileName); File tofile = new File(toFileName); if (tofile.exists()) { tofile.delete(); } // Dispatch.call(doc, "SaveAs", destFile, 17); Dispatch.invoke(doc, "SaveAs", Dispatch.Method, new Object[] { toFileName, new Variant(17) }, new int[1]); long end = System.currentTimeMillis(); System.out.println("转换完成..用时：" + (end - start) + "ms."); } catch (Exception e) { e.printStackTrace(); System.out.println("========Error:文档转换失败：" + e.getMessage()); } finally { Dispatch.call(doc,"Close",false); System.out.println("关闭文档"); if (app != null) app.invoke("Quit", new Variant[] {}); } //如果没有这句话,winword.exe进程将不会关闭 ComThread.Release(); } public static void main(String[] args) { Test d = new Test(); d.wordToPDF("d:\\ftp\\aaa.docx", "d:\\ftp\\aaa.pdf"); }}
