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。
