jeesite导入excel表格做法

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：根据前面两篇博文去操作，建立左树右表的单表增删改查，在原有的根据字段查询数据的查询按钮右边，加入导入按钮

课程表生成

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"

                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">

                <shiro:hasPermission name="jsl:jslCourse:edit">

                </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}"

                    </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

        super();
    }

    public JslCourse(String id){
        super(id);
    }

    @JsonIgnore
    @NotNull(message="归属公司不能为空")
    @ExcelField(title="归属公司", align=2, sort=20)
    public Office getCompany() {
        return company;
    }

    public void setCompany(Office company) {
        this.company = company;
    }

    @JsonIgnore
    @NotNull(message="归属部门不能为空")
    @ExcelField(title="归属部门", align=2, sort=25)

    @ExcelField(title="课程名", align=2, sort=30)
    public String getCoursename() {
        return coursename;
    }

    public void setCoursename(String coursename) {
        this.coursename = coursename;
    }
    @ExcelField(title="课室", align=2, sort=35)
    @Length(min=0, max=64, message="上课教室长度必须介于 0 和 64 之间")
    public String getClassroom() {
        return classroom;
    }

    public void setClassroom(String classroom) {
        this.classroom = classroom;
    }


    @ExcelField(title="听课老师", align=2, sort=40)
    @Length(min=0, max=64, message="听课老师长度必须介于 0 和 64 之间")
    public String getListenteacher() {
        return listenteacher;
    }
    public void setListenteacher(String listenteacher) {
        this.listenteacher = listenteacher;
    }

    @ExcelField(title="任课老师", align=2, sort=45)
    @Length(min=0, max=64, message="任课老师长度必须介于 0 和 64 之间")

    }

    public void setCourseteacher(String courseteacher) {
        this.courseteacher = courseteacher;
    }
    @ExcelField(title="专业班级", align=2, sort=50)

    }
    @ExcelField(title="听课时间", align=2, sort=55)
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    public Date getCoursetime() {
        return coursetime;
    }

    public void setCoursetime(Date coursetime) {
        this.coursetime = coursetime;
    }

}

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
