[Pulgin] 利用swfupload实现java文件批量上传

URL:http://blog.csdn.net/xuweilinjijis/article/details/8876305

之前在网上找过很多相关资料，很多所谓的批量上传都是忽悠人的，真正的批量上传指的是 用户一次性可以选择多个文件，然后上传是将所有选取的文件上传到服务器。java中真正可以实现批量上传的技术大致有两种：一种是通过flash；一种是 通过applet；不过html5也可以支持批量拖选。两种方式有各自的优缺点，其中flash对于浏览器兼容性较好，基本可以满足市面上大众浏览器，缺 点就是对于上传文件大小有限制，如果用户只需要上传一些图片或者文档文件的话，这种选择还是比较理想的；applet方式可以上传大文件，但是需要浏览器 支持jdk并安装相关插件。

      今天这个项目采用的是flash方式。整体设计思路：采用ext+swfupload进行上传界面显示，后台采用strust2来处理上传文件。



最终项目运行效果图如下：
