用到的工具：jacob-1.17-M2.zip，文件解压后主要有三个文件：jacob.jar、jacob-1.17-M2-x64.dll和jacob-1.17-M2-x86.dll。

jacob.jar引入到项目工程中，jacob-1.17-M2-x64.dll放在C:\Windows\System32下，如果系统是32位的则把jacob-1.17-M2-x86.dll放在C:\Windows\System32下。

注意：文件名要用.doc，万不能用.docx。那样会打不开文件

代码示例：

/*

* Java2word.java

*

* Created on 2007年8月13日, 上午10:32

* To change this template, choose Tools | Template Manager

* and open the template in the editor.

*/

/*

* 传入数据为HashMap对象，对象中的Key代表word模板中要替换的字段，Value代表用来替换的值。

* word模板中所有要替换的字段(即HashMap中的Key)以特殊字符开头和结尾，如：$code$、$date$……，

以免执行错误的替换。

* 所有要替换为图片的字段，Key中需包含image或者Value为图片的全路径(目前只判断文件后缀名为：.bmp、

.jpg、.gif)。

* 要替换表格中的数据时，HashMap中的Key格式为“table$R@N”，其中：R代表从表格的第R行开始替换，N代表

word模板中的第N张表格；Value为ArrayList对象，ArrayList中包含的对象统一为String[]，一条String[]代

表一行数据，ArrayList中第一条记录为特殊记录，记录的是表格中要替换的列号，如：要替换第一列、第三列、

第五列的数据，则第一条记录为String[3] {“1”,”3”,”5”}。
