poi导出图片如图：
主要代码：
注：此为SSH项目 条件导出

在前端写两个按钮
<button type="button" onclick="exportExcel2()" class="btn btn-info">
<span class="glyphicon glyphicon-circle-arrow-down"></span>导出Excel
</button>
<button type="button" onclick="importExcel()" class="btn btn-warning">
<span class="glyphicon glyphicon-circle-arrow-up"></span>导入Excel
</button>
定义方法 在条件查询表单中加个id，查询字段都加个name值以便传到后台进行查询
<script type="text/javascript">
// 页面加载函数
$(function(){
//初始化
importExcelHTML = $("#importExcelDiv").html();
})
// 导出Excel
function exportExcel2(){
// 获取条件查询的form表单
var searchForm = document.getElementById("searchForm");
// 给form表单设置提交路径
searchForm.action = "<%=request.getContextPath()%>/excelController/exportExcel2.do";
// 提交form表单
searchForm.submit();
}
// 导入Excel
function importExcel(){
$("#importExcelDiv").html(importExcelHTML);
initImportInput();
importDialog = bootbox.dialog({
title:"<h3>导入Excel</h3>",
message:$("#importExcelDiv form")
})
}
</script>
导入时的弹框
<!-- 导入页面内容 -->
<div id="importExcelDiv" style="display:none;">
<form id="importExcelForm" class="form-horizontal">
<div class="form-group">
<label for="firstname" class="col-sm-2 control-label">选择文件</label>
<div class="col-sm-8">
<input type="file" class="form-control" name="uploadExcel" id="excel"/>
</div>
