POI实现数据表格导出功能（页面—>后台）
需求：需要导出一个excele，导出包含两部分内容（1.jsp界面table 指定的两个列（非全部） 2.手动绘制的一部分其他内容。）最后要将两部分内容合并成一个新的excele并导出。
框架：SpringMVC（功能跟框架实质没关系，只需要关注一点，将所需要的参数传递到对应方法中或者向需要导出的方法发出请求即可）。
由于是变看POI 文档边做，dome 写的不好，现将优化前dome 贴出作为笔记，供后参考。
前端界面使用标签使用href带参 向Controller发起请求： dome 如下；
模板导出
Controller 后台接收参数做处理，调用模板生成类生成模板：dome 如下；
/***
* 导出配置模板
* **/
