近期項目中用到將用戶上傳的word文檔轉換為pdf文件。用java實現，于是乎在google上百度了一下。得出兩種解決方案。
1、使用OpenOffice轉PDF；
2、使用MS Office的OLE自動化功能；
同樣也得到如下的帖子

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 = "D:\\workspace\\word2pdf\\src\\tests.doc";
String toFilename = filename + ".pdf";
System.out.println("啟動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("打開文檔" + filename);
Dispatch doc = Dispatch.call(docs,//
"Open", //
filename,// FileName
false,// ConfirmConversions
true // ReadOnly
).toDispatch();
System.out.println("轉換文檔到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("轉換完成..用時：" + (end - start) + "ms.");
} catch (Exception e) {
System.out.println("========Error:文檔轉換失敗：" + e.getMessage());
} finally {
if (app != null)
app.invoke("Quit", wdDoNotSaveChanges);
}
}
} 需要使用到的jar
jacob.jar
另外拷貝jacob.dll到 Windows System32目錄下
