本篇文章基于java把数据库中的数据以Excel的方式导出，欢迎各位大神吐槽：
1、基于maven jar包引入如下：

|
<dependency>
<groupId>net.sourceforge.jexcelapi</groupId>
<artifactId>jxl</artifactId>
<version>2.6.12</version>
</dependency>
|
2、首先创建数据库对应的实体类VO ：UserVO（具体代码省略）；
3、确定导出Excel内的title列，并放在数组里：String[] （具体代码省略）；
4、编写导出Excel的方法：
传入参数：
Excel名称，Excel内的title列数组String[]，数据集合List<UserVO>
