jeesite匯入excel表格做法
阿新 • • 發佈：2018-11-12
1、利用程式碼生成功能製作好單表增刪改查的模組
2、修改前段程式碼，插入‘匯入’按鈕並且寫好匯入彈出框介面，加入複製貼上使用者模組的前段程式碼
3、修改實體類，加上註釋
4、在控制器加入下載模板和匯入功能的響應方法
第一步：根據前面兩篇博文去操作，建立左樹右表的單表增刪改查，在原有的根據欄位查詢資料的查詢按鈕右邊，加入匯入按鈕
第二步：修改前段程式碼，如下：
<%@ page contentType="text/html;charset=UTF-8"%>
<%@ include file="/WEB-INF/views/include/taglib.jsp" 第三步：實體類中凡是要通過excel匯入的欄位都需要在實體類的欄位的get（）方法添加註釋

}
}第四步：在控制層新增響應匯入按鈕的操作，主要有兩個部分，一個是下載模板、一個是匯入響應
