uploadify + SpringMVC文件批量上傳及下載

週末閒得無事，就隨便寫寫，如標題所示，玩了一下uploadfy上傳組件，相似uploadfy之類的Flash上傳組件有不少，如SWFUpload、Sapload、AlanXUpload等等，對比以後，我最終選擇了uploadfy。

   因爲我比較喜歡用SpringMVC,相對於Struts2來講，SpringMVC更輕巧。不扯這些，仍是先來上幾張我一天勞動成果的效果圖吧！
  








主要作了下使用UploadFy組件實現文件的批量上傳，UploadFy是有帶實時進度信息的，用戶體驗應該還不錯，用戶上傳完成後跳至文件列表頁面，下面的分頁信息是我自定義的分頁標籤，上面就是一些簡單的信息查詢，而後每一個文件均可以點擊「下載」連接直接下載，刪除和編輯功能沒實現，但後臺方法是寫好了的。由於個人重點是學習使用UploadFy組件進行文件上傳下載練習的，因此刪除編輯就忽略了。
    這個小示例程序我採用的是SpringMVC + Hibernate4完成的，項目結構圖以下：


依賴的全部jar包如圖：
