uploadify + SpringMVC文件批量上传及下载

周末闲得无事，就随便写写，如标题所示，玩了一下uploadfy上传组件，类似uploadfy之类的Flash上传组件有很多，如SWFUpload、Sapload、AlanXUpload等等，对比之后，我最终选择了uploadfy。

   由于我比较喜欢用SpringMVC,相对于Struts2来说，SpringMVC更轻巧。不扯这些，还是先来上几张我一天劳动成果的效果图吧！
  








主要做了下使用UploadFy组件实现文件的批量上传，UploadFy是有带实时进度信息的，用户体验应该还不错，用户上传完成后跳至文件列表页面，下面的分页信息是我自定义的分页标签，上面就是一些简单的信息查询，然后每个文件都可以点击“下载”链接直接下载，删除和编辑功能没实现，但后台方法是写好了的。因为我的重点是学习使用UploadFy组件进行文件上传下载练习的，所以删除编辑就忽略了。
    这个小示例程序我采用的是SpringMVC + Hibernate4完成的，项目结构图如下：


依赖的所有jar包如图：
