Java操作Jxl实现导出数据生成Excel表格数据文件

Java操作Jxl实现导出数据生成Excel表格数据文件。

本文实现背景Web项目：前台用的框架是Easyui+Bootstrap结合使用，需要引入相应的Js、Css文件。页面：Jsp、拦截请求：Servlet、逻辑处理：ClassBean、数据库：SQLserver。

注意：Bean中操作SQL语句进行处理是公司内部方法，可替换为其它方法自行扩展！主要看代码逻辑业务处理！

使用SQLserver数据库进行多表连接查询得出需要展出的数据

则前台数据展示使用的是Easyui中的datagrid数据列表进行展示。

随机点击一行数据，点击详情个人信息弹窗打开，数据以及被填充到弹窗中！

拉到底部可见导出按钮，点击导出发送请求：传入个人就诊编号及卡号进行SQL查询个人数据实现导出

此时此刻Java操作Jxl生成Excel文件成功直接，让我们打开文件查看数据是否和我们后台设置的预期效果一致！

表格数据和预期效果一致代码如下：
