開發(fā)文件篩選分類功能

文件分類功能一、目錄21.技術原理2.效果圖預覽3.實現(xiàn)步驟4.功能驗證測試二、技術原理3（1）視圖層：分類展示圖片（2）控制層：接收視圖層的消息，向服務層發(fā)送文件篩選參數(shù)，并將服務層返回的結果發(fā)送到視圖層（3）服務層：獲取當前賬號的所有圖片對象，將圖片對象封裝到集合中返回給控制層三、效果預覽圖4四、步驟實現(xiàn)5在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代碼public

ListgetCategoryStoredList(StringrootPath,int

type){List<?extendsSwiftObject>swiftObjects=this.list(rootPath);logger(rootPath+"執(zhí)行getCategoryStoredList方法，文件分類查詢");List<SwiftObject>objects=newArrayList<>();for(SwiftObjectso:swiftObjects){StringfileName=so.getName();switch(type){case1:if(UtilTools.isImage(fileName)){objects.add(so);}break;case2:if(UtilTools.isDoc(fileName)){objects.add(so);}break;case3:if(UtilTools.isMediea(fileName)){objects.add(so);}break;四、步驟實現(xiàn)6在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代碼case4:if(UtilTools.isMp3(fileName)){objects.add(so);}break;case5:if(!UtilTools.isImage(fileName)&&!UtilTools.isDoc(fileName)&&!UtilTools.isMediea(fileName)&&!UtilTools.isMp3(fileName)&&!so.isDirectory()){objects.add(so);}break;default:break;}}四、步驟實現(xiàn)7在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代碼List<FileBean>list=newArrayList<>();for(SwiftObjectso:objects){FileBeanfb=newFileBean();fb.setName(this.getName(so.getName()));boolean

flag=so.isDirectory();fb.setIsdirectory(flag);if(!flag){fb.setLength(so.getSizeInBytes());}fb.setPath(so.getName());fb.setLastmodified(DateUtil.cstToHMS(so.getLastModified()));list.add(fb);}return

list;}四、步驟實現(xiàn)8publicListgetCategoryStoredList(Stringusername,int

type,Stringupath){SwiftDFSswiftdfs=newSwiftDFS();ListcategoryStoredList=swiftdfs.getCategoryStoredList(username,type);return

categoryStoredList;}在cn/edu/sict/cloud/storage/service/SwiftStorageService.java添加如下代碼9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;}四、步驟實現(xiàn)10給main.jsp的標簽添加鏈接，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>

全部文件</a><aclass="list-group-item"href="category.action?type=2"><spanclass="glyphiconglyphicon-fileleft-icon">
