Spring MultipartFile 文件上传【注解】& JQuery uploader plugin - paggywong - ITeye技术网站
首先准备工作：
我用的是Spring 3.02 +Gson1.71+JQuery 1.52+JQuery Uploader Plugin
applicationContext.xml:
&!-- 激活spring的注解. --&
&context:annotation-config /&
&!-- 扫描注解组件并且自动的注入spring beans中.
例如,他会扫描@Controller 和@Service下的文件.所以确保此base-package设置正确. --&
&context:component-scan base-package="com.swind.web" /&
&!-- 配置注解驱动的Spring MVC Controller 的编程模型.注:次标签只在 Servlet MVC工作! --&
&mvc:annotation-driven /&
dispatcher-servlet.xml
&bean id="multipartResolver" class="org.springframework.monsMultipartResolver"&
&property name="maxUploadSize"&
&value&&/value&
&/property&
&property name="maxInMemorySize"&
&value&4096&/value&
&/property&
&property name="defaultEncoding"&
&value&UTF-8&/value&
&/property&
&servlet-mapping&
&servlet-name&Dispatcher&/servlet-name&
&url-pattern&/&/url-pattern&
&/servlet-mapping&
服务端：Controller、Service都是从网上Copy来的，加以修改。
Controller：
为JQuery uploader 删除增加了一个handleDelete方法。

3秒自动关闭窗口extjs - How to get Sencha file upload field to accept multiple files - Stack Overflow
Join the Stack Overflow Community
Stack Overflow is a community of 7.1 million programmers, just like you, helping each other.
J it only takes a minute:
I have Sencha Ext JS application where I use File form field (Ext.form.field.File) to upload files. It's working fine, but I want users to be able to select multiple files for upload at once, like , for example. I have another, non-Sencha site (in which I had direct control over HTML) where I solved this problem by using multiple attribute of the INPUT element:
&input type="file" name="files" multiple&
Sencha, however, doesn't support multiple files in file upload field natively, at least as of current version (4.1). Perhaps it's possible to alter HTML output emitted by Sencha for &input& element, but I am not sure how.
You can create a xtype:
Ext.define('fileupload',{
extend: 'Ext.form.field.Text'
,alias: 'widget.fileupload'
,inputType: 'file'
,listeners: {
render: function (me, eOpts) {
var el = Ext.get(me.id+'-inputEl');
size: me.inputSize || 1
if(me.multiple) {
multiple: 'multiple'
And use it in your form:
,items: [{
xtype: 'fileupload'
,vtype: 'file'
,multiple: true // multiupload (multiple attr)
,acceptMimes: ['doc', 'xls', 'xlsx', 'pdf', 'zip', 'rar'] // file types
,acceptSize: 2048
,fieldLabel: 'File &span class="gray"&(doc, xls, xlsx, pdf, zip, 2 MB max)&/span&'
,inputSize: 76 // size attr
,msgTarget: 'under'
,name: 'filesToUpload[]'
See example on
There is a plugin for this maybe you can use it:
