本文介绍如何使用jacob库在Word中添加水印，特别指出如何修改代码以仅在文档的最后一页插入水印，避免了全局覆盖的问题。

想请教一下大佬们我是用jacob来为word添加水印，word添加上了但是是所有页面dou都添加了，请问一下怎么只在word最后一页添加水印呢？

代码如下

package com.oa.commons.jacob;

   /**
   * Created by qiuzhb on 2018/5/29.
   * 给word文档添加水印
   */
import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.ComThread;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;
import com.oa.commons.util.FileUtils;

/**

* 给word文档添加水印
*/
public class test2 {
   // 声明一个静态的类实例化对象
//private static AddWatermarkUtil test;
// 声明word文档对象
private Dispatch doc = null;
// 声明word文档当前活动视窗对象
private Dispatch activeWindow = null;
// 声明word文档选定区域或插入点对象
private Dispatch docSelection = null;
// 声明所有word文档集合对象
private Dispatch wrdDocs = null;
// 声明word文档名称对象
private String fileName;
// 声明ActiveX组件对象：word.Application,Excel.Application,Powerpoint.Application等等
private ActiveXComponent wrdCom;

   /**

*
* @param wordPath
* word文档的路径
* @param waterMarkPath
* 添加的水印图片路径
* @return 是否成功添加
*/
//第一次签名调用此方法此方法不会出现还没添加就删除的报错
public boolean addWaterMark(String wordPath, String waterMarkPath,int left,int top) {
try {
if (initWordObj()) {
openDocument(wordPath);
getActiveWindow();
setWaterMark(waterMarkPath,left,top);
closeDocument();
closeWordObj();
return true;

} else
return false;
} catch (Exception e) {
e.printStackTrace();
closeDocument();
closeWordObj();
return false;
}
}
//重新签名调用此方法
public boolean addWaterMark1(String wordPath, String waterMarkPath,int left,int top) {
try {

} else
