struts：poi讀取excel檔案（相容2003、2007）
阿新 • • 發佈：2019-01-10
1、jsp程式碼：
<div style="margin-bottom:10px;"> <input type="file" name="filedata" id="file" multiple/> <input type="button" value="上傳" id="fileBtn"/> </div> <div style="margin-bottom:10px;"> 款項稽核頁-資料匯出為excel-資料格式.xlsx<a id="downBtn1" href="">下載1</a><input type="button" value="下載2" id="downBtn2"/> </div>
$("#fileBtn").click(function() { //獲取上傳圖片的檔名 var confirmfileImageName =$("#file").val(); //員工是否選擇了圖片 if(confirmfileImageName!=""){ $.ajaxFileUpload({ url:'ExcelReadAction', secureuri:false, fileElementId:'file',//file標籤的id dataType: 'json',//返回資料的型別 data:{},//一同上傳的資料 success: function (ret) {alert("上傳成功"); } }); } else { } }) $("#downBtn1").attr("href","/file/款項稽核頁-資料匯出為excel-資料格式.xlsx"); $("#downBtn2").click(function() { $.ajaxFileUpload({ url:'ExcelWriteAction', secureuri:false, fileElementId:'file',//file標籤的id dataType: 'json',//返回資料的型別 data:{},//一同上傳的資料 success: function (ret) {alert("上傳成功"); } }); })
2、struts配置
<!-- excel讀取 --> <action name="ExcelReadAction" class="com.dld.app.sales.action.ExcelOperateAction" method="excelRead"> <result type="json" name="success"> <param name="contentType">text/html</param> </result> </action> <!-- excel下載 --> <action name="ExcelWriteAction" class="com.dld.app.sales.action.ExcelOperateAction" method="excelWrite"> <result type="json" name="success"> <param name="contentType">text/html</param> </result> </action>
