1、利用代码生成功能制作好单表增删改查的模块
2、修改前段代码，插入‘导入’按钮并且写好导入弹出框界面，加入复制粘贴用户模块的前段代码
3、修改实体类，加上注释
4、在控制器加入下载模板和导入功能的响应方法
第一步：界面 加入导入按钮
第二步：修改前段代码，如下：
<%@ page contentType="text/html;charset=UTF-8"%>
<%@ include file="/WEB-INF/views/include/taglib.jsp"%>
<html>
<head>
<title>课程表管理</title>
<meta name="decorator" content="default" />
<script type="text/javascript">
$(document).ready(function() {
$("#btnImport").click(function(){
$.jBox($("#importBox").html(), {title:"导入数据", buttons:{"关闭":true},
bottomText:"导入文件不能超过5M，仅允许导入“xls”或“xlsx”格式文件！"});
});
});
function page(n, s) {
$("#pageNo").val(n);
$("#pageSize").val(s);
$("#searchForm").submit();
return false;
}
</script>
</head>
<body>
<div id="importBox" class="hide">
<form id="importForm" action="${ctx}/jsl/jslCourse/import"
method="post" enctype="multipart/form-data" class="form-search"
style="padding-left: 20px; text-align: center;"
onsubmit="loading('正在导入，请稍等...');">
<br />
<input id="uploadFile" name="file" type="file"
style="width: 330px" />
<br /> <br />
<input id="btnImportSubmit"
class="btn btn-primary" type="submit" value=" 导 入 " /> <a
href="${ctx}/jsl/jslCourse/import/template">下载模板</a>
</form>
</div>
<ul class="nav nav-tabs">
<li class="active"><a href="${ctx}/jsl/jslCourse/">课程表列表</a></li>
<shiro:hasPermission name="jsl:jslCourse:edit">
<li><a href="${ctx}/jsl/jslCourse/form">课程表添加</a></li>
</shiro:hasPermission>
</ul>
<form:form id="searchForm" modelAttribute="jslCourse"
action="${ctx}/jsl/jslCourse/" method="post"
class="breadcrumb form-search">
<input id="pageNo" name="pageNo" type="hidden" value="${page.pageNo}" />
<input id="pageSize" name="pageSize" type="hidden"
value="${page.pageSize}" />
<ul class="ul-form">
<li><label>上课教室：</label> <form:input path="classroom"
htmlEscape="false" maxlength="64" class="input-medium" /></li>
<li><label>任课老师：</label> <form:input path="courseteacher"
htmlEscape="false" maxlength="64" class="input-medium" /></li>
<li class="btns"><input id="btnSubmit" class="btn btn-primary"
type="submit" value="查询" /></li>
<li class="btns"><input id="btnImport" class="btn btn-primary"
type="button" value="导入" /></li>
<li class="clearfix"></li>
</ul>
</form:form>
<sys:message content="${message}" />
<table id="contentTable"
class="table table-striped table-bordered table-condensed">
<thead>
<tr>
<th>归属公司</th>
<th>归属部门</th>
<th>课程名称</th>
<th>上课教室</th>
<th>听课老师</th>
<th>任课老师</th>
<th>专业班级</th>
<th>听课时间</th>
<th>更新时间</th>
<th>备注信息</th>
<shiro:hasPermission name="jsl:jslCourse:edit">
<th>操作</th>
</shiro:hasPermission>
</tr>
</thead>
<tbody>
<c:forEach items="${page.list}" var="jslCourse">
<tr>
<td><a href="${ctx}/jsl/jslCourse/form?id=${jslCourse.id}">
${jslCourse.company.name} </a></td>
<td>${jslCourse.office.name}</td>
<td>${jslCourse.coursename}</td>
<td>${jslCourse.classroom}</td>
<td>${jslCourse.listenteacher}</td>
<td>${jslCourse.courseteacher}</td>
<td>${jslCourse.professionalclass}</td>
<td><fmt:formatDate value="${jslCourse.coursetime}"
pattern="yyyy-MM-dd HH:mm:ss" /></td>
<td><fmt:formatDate value="${jslCourse.updateDate}"
pattern="yyyy-MM-dd HH:mm:ss" /></td>
<td>${jslCourse.remarks}</td>
<shiro:hasPermission name="jsl:jslCourse:edit">
<td><a href="${ctx}/jsl/jslCourse/form?id=${jslCourse.id}">修改</a>
<a href="${ctx}/jsl/jslCourse/delete?id=${jslCourse.id}"
onclick="return confirmx('确认要删除该课程表吗？', this.href)">删除</a></td>
</shiro:hasPermission>
</tr>
</c:forEach>
</tbody>
</table>
<div class="pagination">${page}</div>
</body>
</html>
第三步：实体类中凡是要通过 excel 导入的字段都需要在实体类的字段的 get（）方法添加注释

第四步：在控制层添加响应导入按钮的操作，主要有两个部分，一个是下载模板、一个是导入响应
