java操作word文档(jacob,poi)

项目需要,用户从系统里面下载word文档,该文档进行了填写限制和加密,用户只能在固定位置填写内容。现要求系统验证上传的附件是否从系统上下载下来的。

思路:系统上面的文档都加入一个固定书签,用户上传文档的时候,检验文档里是否包含这个书签。

采用jacob操作word文档

 

JACOB(java -com bridge)是一个 JAVA到微软的COM接口的桥梁。使用JACOB允许任何JVM访问COM对象,从而使JAVA应用程序能够调用COM对象。

下载地址:http://sourceforge.net/projects/jacob-project/

 

其中jacob-1.16.1-x64.dll 是用于64位机器上的,jacob-1.16.1-x86.dll用于32位的。

该dll放于 C:\Windows\system32 目录下。jacob.jar放于应用lib底下

测试代码

ActiveXComponent	word = null;
try {
        word = new ActiveXComponent("Word.Application");
        System.out.println("jacob当前版本:"+word.getBuildVersion());
}catch(Exception e ){
         e.printStackTrace();
}

下面再贴出网上常见的代码+自己整理的几个方法(模糊查询书签等)

注意插入书签+书签值的方法,要先插入书签值再选中书签值,之后插入书签。这样根据书签名才能取得书签值。否则根据网络上很多方法,都取不到书签值或者取到空。因为书签值可以是一个点也可以是一大段内容。

 采用jacob方式操作文档,经常会出现卡机的现象,所以最后采用poi方式来操作书签。若单纯的操作书签用poi方式还是比较简单的,但要操作表格、文档格式之类的还是用jacob功能比较强大。

InputStream input = null;
File docFile = new File( fileName );
HWPFDocument document = null;
try{
	input = new FileInputStream(docFile);//加载 doc 文档
	document = new HWPFDocument(input);//文件流方式创建hwpf
	Bookmarks bookmarks =  document.getBookmarks();//文档书签
	for(int i=0,length=bookmarks.getBookmarksCount();i<length;i++){
		bookmarkName = bookmarks.getBookmark(i).getName();
		//.....
	}
	
}catch( Exception e){
	
}finally{
	if( null != input )
			input.close();
}
