Spring+SpringMVC+Maven+MyBatis+Mysql此环境下的POI导入
此文档讲解Excel导入的功能
1.1 POI导入excel
浏览器效果展示：
前端代码
前端Html代码：
<!-- 导入 -->
<div class="layui-inline">
<div class="layui-input-block" style="margin-left: 10px;">
<button type="button" permission="49" class="layui-btn layui-btn-small">

Js代码
//JS校验form表单信息
<script>
