java 根据word模板生成word 文档
先下载jacob_1.10.1.zip。
解压后将jacob.dll放到windows/system32下面或\j2sdk\bin下面。
将jacob.jar加入项目。
/*
* Java2word.java
*
* 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”}。
