Java將WORD轉成PDF

開發環境：windows。請務必在windows操做系統中進行本操做，由於word須要在服務器上轉爲pdf。

請在電腦上安裝word，注意是安裝word，不是安裝wps（這一點很是重要）。

請在電腦上安裝word轉pdf的插件：「軟件名：SaveAsPDFandXPS」，下載地址：http://download.csdn.net/download/tiandixuanwuliang/10006993

請把系統須要調用的dll文件放置在java環境的jre的bin目錄下，例如：C:\Program Files\Java\jdk1.7.0_13\bin\jacob-1.18-x64.dll，（請注意本身電腦32位仍是64位）下載地址：http://download.csdn.net/download/tiandixuanwuliang/10007003

將jacob.jar放到C:\Windows\System32目錄下。同時將其引入的工程文件中。

工程中的使用方式以下：

import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;
import com.lowagie.text.Document;
import com.lowagie.text.DocumentException;
import com.lowagie.text.Image;
import com.lowagie.text.PageSize;
import com.lowagie.text.pdf.PdfWriter;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
