云存儲(chǔ)文件分類功能

云存儲(chǔ)文件分類功能目錄技術(shù)原理實(shí)現(xiàn)步驟功能描述功能測(cè)試2技術(shù)原理3（1）視圖層：分類展示圖片（2）控制層：接收視圖層的消息，向服務(wù)層發(fā)送文件篩選參數(shù)，并將服務(wù)層返回的結(jié)果發(fā)送到視圖層（3）服務(wù)層：獲取當(dāng)前賬號(hào)的所有圖片對(duì)象，將圖片對(duì)象封裝到集合中返回給控制層功能描述4實(shí)現(xiàn)步驟5在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代碼public

ListgetCategoryStoredList(StringrootPath,int

categoryStoredList;}實(shí)現(xiàn)步驟10在cn/edu/sict/cloud/storage/Web/StorageController.java添加如下代碼@RequestMapping("/category")publicModelAndViewcategory(HttpServletRequestrequest,HttpServletResponseresponse,int

type){ModelAndViewview=newModelAndView();Useruser=getSessionUser(request);Stringupath=request.getSession().getServletContext().getRealPath("/");Listlist=storage.getCategoryStoredList(user.getUsername(),type,upath);view.addObject("list",list);view.addObject("search","true");view.addObject("type",type);view.setViewName("/main");return

view;}實(shí)現(xiàn)步驟11給main.jsp的標(biāo)簽添加鏈接，代碼如下：<divclass="list-groupcategory"style="margin:10px;"><aclass="list-group-item"id="r_active"href="home.action"><spanclass="glyphiconglyphicon-homeleft-icon"></span>
