<script type="text/javascript" src="${ctxStatic}/js/jquery-form.js"></script>

$("#btnImportSubmit").click(function(){
var filepath = $("input[name='file']").val();
if(filepath!=""){
//ajaxFileUpload();
uploadPortraits();

CC.alert("没有要上传的文件!");
}
});

function uploadPortraits() {
var fileForm = $("#uploadForm");
var options  = {    
     url:'${ctx}/customer/admin/FinancialDataCollection/upload',    
     type:'post',  
     success:function(data){
     initData(data.resultData);
      $("#file").val("");
     },
     error: function (data, status, e){
              CC.alert("上传失败,请稍后在试!");
         }
 };
fileForm.ajaxSubmit(options);
}

Controller层

public Map<String,Object> upload(@RequestParam("file") MultipartFile file,HttpServletRequest request,Model model){}

之前由于使用ajaxFileUpload插件进行Excel上传,由于某些原因不兼容IE11,所以使用此方法替换.
