以上是java部分的代码， 导出按照workbook-->sheet-->row-->cell的大体流程走， 再加上格式设置， 加上值等等
前端需要弹出下载框，可以用：
window.open("objectgroup.do"+"?action=exportAssetExcel&ogid="+ogid+"&objectgroupname="+objectgroupname);
或者用form提交
jsp页面
<form action="exportExcel_program" method="post" id="exportExcel_program_form">
<input type="hidden" name="searchXML" id="searchXML"/>
</form>
js处理
$("#searchXML").val(searchXML);
$("#exportExcel_program_form").submit();
这里参数可能有中文，所以java部分要处理，可以参见上面java代码
