解决如何使用layui导入Excel表数据

1.前端页面html代码展示

 <button type="button" lay-submit="" class="layui-btn layui-btn-warm" lay-  filter="uploadImg"><i class="layui-icon"></i>导出Excel</button>

2.前端页面js代码展示

 layui.use(['table', 'form', 'layer', 'vip_table',"element", "laypage", "upload"],    function () {// 操作对象var form = layui.form, table = layui.table, layer = layui.layer, vipTable = layui.vip_table, $ = layui.jquery;var element = layui.element;var laypage = layui.laypage;var upload = layui.upload;//主要是这个//导入excel表//选完文件后不自动上传upload.render({elem: '#importData',url: '${pageContext.request.contextPath }/infoSheet/ajaxUpload',auto: true,accept: 'file' //普通文件//,multiple: true// ,bindAction: '#test19',done: function(res){console.log(res)//上传完毕//如果上传失败if(res.code > 0){return layer.msg("导入失败",{icon:5,time:1000});}//上传成功return layer.msg("导入成功",{icon:6,time:1000});}});});

3.java后台代码
