Excel导入功能(Ajaxfileupload)

前言：

前端采用Easyui+Ajaxfileupload实现

后端采用springmvc框架，其中把解析xml封装成了一个jar包，直接调用即可

准备：

前端需要导入（easyui导入js省略，自行导入即可）
Ajaxfileupload.js 下载地址：http://files.cnblogs.com/files/holdon521/ajaxfileupload.zip
后端需要导入：
ht-excel.jar      下载地址：http://files.cnblogs.com/files/holdon521/ht-excel.zip

前端代码：

<div class="easyui-layout" fit="true" style="overflow-y:auto;">
        <div class="ht-info">
            <div class="ht-tip icon-tip"></div>
            <div>电视台类型导入</div>
        </div>
        <div>
               <form id="uploadform" action="" method="post" enctype="multipart/form-data">
                <table>
                    <tr>
                        <td>请选择文件:</td>
                        <td>
                        <input type="file" name="file" id="file" ></input>
                        </td>
                    </tr>
                </table>
            </form>
        </div>
        <div region="south" border="false" style="text-align:right;height:30px;line-height:30px;background:#EAF2FF;">
            <a href="#" onclick="ajaxFileUploadForType()"class="easyui-linkbutton" icon="icon-ok" >提交</a>
            <a class="easyui-linkbutton" icon="icon-cancel" href="javascript:$ht.win.close('uploadTvType')">取消</a>

</div>
<script type="text/javascript">

后端代码：

注：实体类对应Excel里列名称，可以设置非空校验（如果为空，这默认该行数据获取不到），重写父方法即可，以下代码注释重写了
