一、实现页面导入excel
目录：1.配置文件 2.页面展示 3.后台代码 4.图片粘贴演示1.配置文件
<!-- 文件上传-->
码 
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!--1024*200即最大支持上传200kB,如果有需求可以调大，依次类推。-->
<property name="maxUploadSize" value="204800"/>
<!--resolveLazily属性启用是为了推迟文件解析，以便在UploadAction 中捕获文件大小异常-->
<property name="resolveLazily" value="true"/>
</bean> 2.页面展示

<span>注意事项:</span><br>
<p>1、通过此功能将外部渠道的信息导入到CLM系统。</p>
<p>2、导入的Excel不能隐藏列(如果有隐藏列会导致导入数据出现问题)。</p>
<p>3、目前只支持excel(以.xlsx或.xls结尾)文件导入，请下载Excel模板并严格按模板要求整理信息数据。<a href="/upload/importExcelTemplate.xlsx">excel模板下载</a></p>
<p>注释：如果需要增加列，请联系开发人员。</p>

<form name = "frm" action="/clm/clmCustomer/excelImport" method="post" enctype="multipart/form-data">

alert("请选择导入的文件！");
}else{

@RequestMapping(value = "/clmCustomer/excelImportView", method = { RequestMethod.GET })
public String list(HttpServletRequest request, Model model, HttpServletResponse response) {
return "/clmpool/excelImportView";//导出页面
}

* @return
*/

@ResponseBody
@Transactional
