java 利用jacob将word转换成PDF

工作原理：调用word本身自带的另存为PDF格式

注意：JDK1.6 要使用jacob1.8+；JDK1.7要使用jac1.8-

注意32位和64的.dll的选择 以及.dll放的位置system32下（最好在自己电脑的jdk/bin下也放上）

import java.io.File;

import com.jacob.activeX.ActiveXComponent;

import com.jacob.com.Dispatch;

public class Word2PDF {

static final int wdDoNotSaveChanges = 0;// 不保存待定的更改。

static final int wdFormatPDF = 17;// PDF 格式

public static void main(String[] args) {

String filename = "e:/resource/s.doc";

String toFilename = filename + ".pdf";

System.out.println("启动Word...");

long start = System.currentTimeMillis();

ActiveXComponent app = null;

try {

app = new ActiveXComponent("Word.Application");

app.setProperty("Visible", false);

Dispatch docs = app.getProperty("Documents").toDispatch();

System.out.println("打开文档..." + filename);

Dispatch doc = Dispatch.call(docs,//

"Open", //

filename,// FileName

false,// ConfirmConversions

true // ReadOnly

).toDispatch();

System.out.println("转换文档到PDF..." + toFilename);

File tofile = new File(toFilename);

if (tofile.exists()) {

tofile.delete();

}

Dispatch.call(doc,//

"SaveAs", //

toFilename, // FileName

wdFormatPDF);

Dispatch.call(doc, "Close", false);

long end = System.currentTimeMillis();

System.out.println("转换完成..用时：" + (end - start) + "ms.");

} catch (Exception e) {

System.out.println("========Error:文档转换失败：" + e.getMessage());

} finally {

if (app != null)

app.invoke("Quit", wdDoNotSaveChanges);

}

}
