/** ExcelUtil工具类实现功能:* 导出时传入list<T>,即可实现导出为一个excel,其中每个对象Ｔ为Excel中的一条记录.* 导入时读取excel,得到的结果是一个list<T>.T是自己定义的对象.* 需要导出的实体对象只需简单配置注解就能实现灵活导出,通过注解您可以方便实现下面功能:* 1.实体属性配置了注解就能导出到excel中,每个属性都对应一列.* 2.列名称可以通过注解配置.* 3.导出到哪一列可以通过注解配置.* 4.鼠标移动到该列时提示信息可以通过注解配置.* 5.用注解设置只能下拉选择不能随意填写功能.* 6.用注解设置是否只导出标题而不导出内容,这在导出内容作为模板以供用户填写时比较实用.*/
