/**
* 共分为六部完成根据模板导出excel操作：
* 第一步、设置excel模板路径（setSrcPath）
* 第二步、设置要生成excel文件路径（setDesPath）
* 第三步、设置模板中哪个Sheet列（setSheetName）
* 第四步、获取所读取excel模板的对象（getSheet）
* 第五步、设置数据（分为6种类型数据：setCellStrValue、setCellDateValue、setCellDoubleValue、setCellBoole、setCellCalendarValue、setCellRichTextStrValue）
* 第六步、完成导出 （exportToNewFile）
