        response.reset();
        excelUtils.setResponse(response);
        excelUtils.setDataLists(dataList);

        excelUtils.setFileName("安全风险认领");
        excelUtils.exportForExcelsOptimize();

    }

前端：由于Ajax回调函数不能处理  所以在前端写了一个隐藏起来的form表单当作 条件载体 

<a class="btn size-M btn-primary radius" href="javascript:void(0);" id="export"><i class="Hui-iconfont">&#xe644;</i> 导出</a>

<form id='downloadR' class='hidden' method='get' action="../../xxxx/getExcle">
    <input id="dateYearMonthR" type="text" name="dateYearMonth"/>
</form>

然后js

$('#export').click(function () {
        var dateYearMonth = $('#dateYearMonth1').val();
        if (dateYearMonth) {
            //给表单里的内容填充   传到后台当作条件进行数据库查询
            $('#dateYearMonthR').val(dateYearMonth);
            $('#downloadR').submit();
        } else {
            layer.msg('请选择已经添加过的认领单!',{icon:0, time: 3000});
        }
    });
