一、開發功能介紹： 簡單的一個excel匯入功能

二、Excel匯入模板（大致模板沒寫全）：

三、實體類註解：按照如下註解使用官網提供的匯入匯出方法即可實現功能。

}

四、過程中遇到的坑

　　註解只寫 @Excel(name = "綜合",orderNum = "24",groupName = "客戶分類"），匯入的時候，在分組結束後欄位聯絡人姓名的值無法獲取。網上百度了好多方法也沒有找到原因所在，官網聯絡也沒有得到原因。

　　所以根據官網的屬性介紹，添加了fixedIndex屬性，固定死列數，親測可以解決這個問題，但是這裡要注意 fixedIndex必須從0開始，否則會錯位獲取。

　　好了，大概就寫到這裡，如果有遇到以上和我一樣的問題，並且有更好的解決方式，歡迎留言評論，一起成長，謝謝各位大佬的指點！
