Java导出Excel使用POI之SXSSFWorkbook方式

这里用来自我总结和参考，所以东西看起来可能会有些乱。

<a class="easyui-linkbutton" id='export' iconCls="icon-export" plain="false" onclick="mesExceptionBill.exportServerData(1);" href="javascript:void(0);">导出Excel(带回复)</a>
<a class="easyui-linkbutton" id='exportNoReply' iconCls="icon-export" plain="false" onclick="mesExceptionBill.exportServerData(2);" href="javascript:void(0);">导出Excel</a>

//Excel服务器端导出
MesExceptionBill.prototype.exportServerData = function(exportType) {
    $('#exportType').val(exportType);
    var param = JSON.stringify(serializeObject($('#mesExceptionBill').form()));
    var url = "platform/mms/mes/mesexceptionbillz/mesExceptionBillController/operation/sub/"
            + "exportServer?param=" + param;// 服务器请求地址
    var a = document.getElementById("export");
    a.setAttribute("href", url);
    a.setAttribute("target", "_blank");
    var b = document.getElementById("exportNoReply");
    b.setAttribute("href", url);
    b.setAttribute("target", "_blank");
