JAVA导入EXCEL文件，并且返回详细的导入信息（包括：成功、失败、原因）绝版
需要引入的文件全部由我自己封装（包括：Base64Util.java），随后几篇文章里我会逐个提供：
form表单
返回导入信息展示所需的div
数据导入情况分析：
关闭
总条数
成功数
失败数
相关的JS方法：
function alter(){
var v = $("#uploadEventFile").val();
if(v != ""){
// 避免多次点击按钮导致重复提交表单，msg反回页面后，页面会自动刷新，disabled将被解除 lenian 2018 06 14
$('#submitBtn').attr('disabled',true);
return true;
} else {
//confirm('请选择excel,再导入！');
alert("请选择您需要导入的Excel！");
return false;
}
}表单提交：
// submit提交方法(传参数)，原因：有些站段同时属于多个处室，必须通过传值判断
function toSubmit() {
var officeid = getUrlParam("officeid");
if(officeid == null) {
officeid = $("#deptid").val();
} else {
officeid = getUrlParam("officeid").replace("#", "")
}
$("#deptid", "#batchUpload").val(officeid);
}注：该方法用作页面接收参数用，适用于JSP、html等
function getUrlParam(k) {
var regExp = new RegExp('([?]|&)' + k + '=([^&]*)(&|$)');
var result = window.location.href.match(regExp);
if (result) {
return decodeURIComponent(result[2]);
} else {
return null;
}
