使用Uploadify上传并解析Excel-优快云博客

实际上就是附件上传上传之后用解析excel

示例：

1.用uploadfy上传需要jquery.uploadify.v2.1.4.min.js

js:

$("#attach").uploadify({
'uploader': '/resource/js/plugs/uploadify/uploadify.swf',//进度条，Uploadify里面含有
'script': '/meter/importMeterReading',//一般处理程序
'cancelImg': '/resource/js/plugs/uploadify/cancel.png',//取消图片路径
'buttonImg': '/resource/js/plugs/uploadify/uploadButton.jpg',//图片路径
'queueID': 'up_file_queue',
'auto': true,
'multi': true,
fileDataName : "attach",
height : 27,
width : 63,
method:'post',
removeCompleted : true,
fileExt:"*.xls;*.xlsx;",
fileDesc : 'xls;xlsx;',
sizeLimit:'10485760',
onComplete:function(event, ID, fileObj, response, data){
jQuery("#" + jQuery(event.target).attr('id') + ID).find('a').attr('href','javascript:void(0)').click(function(){
var ao = jQuery.parseJSON(response);
deleteAffix(ao.id,ao.filename,$(this));
});
jQuery("#" + jQuery(event.target).attr('id') + ID).addClass('completed');
//判断返回值
if(response=="\"fail\""){
$.messageBox({message:"导入失败",level: "error"});
return false;
}else if(response=="\"3\""){
$.messageBox({message:"只支持xls和xlsx格式",level: "info"});
$('#attach').uploadifyClearQueue();
return false;
}else if (response=="\"1\""){
$.messageBox({message:"请选择系统提供的模板",level: "info"});
$('#attach').uploadifyClearQueue();
return false;
}else{
$("#meterDialog").createDialog({
url:'/meter/toSureRecording',
width:870,
title:"请核对信息"
});
}
},
onError:function(event,ID,fileObj,errorObj){
debugger;
$.messageBox({message:"上传有误",level: "error"});
$('#attach').uploadifyClearQueue();
}
});

java：

public Object uploadContract(MultipartFile attach,HttpServletRequest request)
throws Exception {
try {
String uploadFileFileName=attach.getOriginalFilename();
String ext = uploadFileFileName.substring(uploadFileFileName
.lastIndexOf("."));
MeterRecordExcel excelReader=new MeterRecordExcel();
Object result=null;
if(ext.equals(".xls")){
result=excelReader.readExcelXLS(attach.getInputStream());
}else if(ext.equals(".xlsx")){
result=excelReader.readExcelXLSX(attach.getInputStream());
}else{
return 3;
}
if(null!=result && !result.toString().equals("1") && !result.toString().equals("3")){
//解析result 判断获取的数据是否合法
List<Map<String,Object>> importList=meterReadingRecordService.fenxiResultExcel((List<MeterRecord>)result);
request.getSession().setAttribute("importList", importList);
result="2";
}
return result;
} catch (Exception e) {
e.printStackTrace();
}
return "fail";
}
