java不同方式方式導入導出數據

方法一： 根據  easypoi  實現導入導出

導入：

前端部分：

<div style="vertical-align:top;padding-left:5px; position: relative; display:inline">
                <input id="excle" type="file" class="btn"/>
                <input  type="file" class="btn" style="position: absolute; width: 30px; height: 30px; top:0;opacity: 0">
            </div>

js:

$("#excle").change(function(){
        var file= document.getElementById("excle").files[0];
        var formData=new FormData();
        formData.append("file",file);
        top.jzts();
        $.ajax({
            //bbk2300/lecturerExcelImport.do
            url : "<%=basePath%>oce6001/Map6001ExcelImport.do",
            type : "POST",
            dataType:"JSON",
            data : formData,
            // 告訴jQuery不要去處理髮送的數據
            processData : false,
            // 告訴jQuery不要去設置Content-Type請求頭
            contentType : false,
            success:function (data) {
                top.hangge();
                tosearch(1);
                alert(data.meta.msg);
            },
            error: function(XMLHttpRequest, textStatus, errorThrown){
                top.hangge();
                tosearch(1);
                alert(JSON.parse(XMLHttpRequest.responseText).msg);
            }
        });

    })
