云存储文件列表功能

云存储文件列表功能目录技术原理实现步骤功能描述功能测试2技术原理3（1）视图层：展示所有文件信息（2）控制层：接收视图层的消息，向服务层发送文件列表参数，并将服务层返回的结果发送到视图层（3）服务层：获取当前账号的云存储对象，将获取到的云存储对象转换为本地模拟文件系统功能描述4实现步骤5在cn/edu/sict/cloud/storage/sh/bean文件夹下创建FileBean.javapublic

classFileBean{private

boolean

isdirectory;//是否是目录private

boolean

haschild;//是否有子文件夹privateStringname;//文件名称privateStringpath;//文件路径privateStringlength;//文件大小privateStringlastmodified;//最后修改时间privateStringfilepath;//如果是文件，存放文件的临时路径public

booleanisHaschild(){return

haschild;}public

voidsetHaschild(boolean

haschild){this.haschild=haschild;}public

booleanisIsdirectory(){return

isdirectory;}public

voidsetIsdirectory(boolean

isdirectory){this.isdirectory=isdirectory;}实现步骤6在cn/edu/sict/cloud/storage/sh/bean文件夹下创建FileBean.javapublicStringgetFilepath(){return

filepath;}public

voidsetFilepath(Stringfilepath){this.filepath=filepath;}publicStringgetLength(){return

length;}public

voidsetLength(long

length){this.length=UtilTools.convertFileSize(length);}publicStringgetLastmodified(){return

lastmodified;}public

voidsetLastmodified(Stringlastmodified){this.lastmodified=lastmodified;}publicStringgetName(){return

name;}public

voidsetName(Stringname){=name;}publicStringgetPath(){return

path;}public

voidsetPath(Stringpath){this.path=path;}}实现步骤7在cn/edu/sict/cloud/storage/sh/文件夹下swiftDFS.java添加如下代码publicListgetFile(Stringrpath){Mapmappath=this.getSplitPath(rpath);StringrootPath=mappath.get("rootPath").toString();Stringpath=mappath.get("path").toString();List<?extendsSwiftObject>objs=this.list(rootPath,path);Listlist=newArrayList();for(SwiftObjectobj:objs){FileBeanfb=newFileBean();StringfilePath=obj.getName();fb.setPath(filePath);fb.setName(this.getName(filePath));boolean

flag=this.isDirectory(filePath);fb.setIsdirectory(flag);实现步骤8在cn/edu/sict/cloud/storage/sh/文件夹下swiftDFS.java添加如下代码if(!flag){ fb.setLength(obj.getSizeInBytes());}fb.setLastmodified(DateUtil.cstToHMS(obj.getLastModified()));list.add(fb);} return

list;}实现步骤9在cn/edu/sict/cloud/storage/sh/文件夹下swiftDFS.java添加如下代码privateMap<String,String>getSplitPath(Stringpath){String[]strPath=path.split("/");StringrootPath="";path="";for(int

i=0;i<strPath.length;i++){if(i==0){rootPath=strPath[0];}else{if(i==strPath.length-1){if(strPath[i].contains(".")){path+=strPath[i];}else{path+=strPath[i]+"/";}实现步骤10在cn/edu/sict/cloud/storage/sh/文件夹下swiftDFS.java添加如下代码}else{path+=strPath[i]+"/";}}}Mapmap=newHashMap();map.put("rootPath",rootPath);map.put("path",path);return

map;}实现步骤11在cn/edu/sict/cloud/storage/util文件夹下新建ComparatorFile.javapublic

classComparatorFileimplementsComparator<FileBean>{publicComparatorFile(){}public

intcompare(FileBeanf1,FileBeanf2){boolean

f1dir=f1.isIsdirectory();boolean

f2dir=f2.isIsdirectory();if(f1dir&&f2dir){return0;}else

if(!f1dir&&f2dir){return1;}else

if(f1dir&&!f2dir){return-1;}else

if(!f1dir&&!f2dir){return0;}return0;}}实现步骤12在cn/edu/sict/cloud/storage/service/SwiftStorageService.java添加如下代码publicListgetAllStoredList(Stringusername,Stringpath){SwiftDFSswiftdfs=newSwiftDFS();Stringup=null;up=username+"/"+path;Listlist=swiftdfs.getFile(up);ComparatorFilecomparator=newComparatorFile();

if(!list.isEmpty()){

synchronized(list){Collections.sort(list,comparator);

}

}return

list;}实现步骤13在cn/edu/sict/cloud/storage/Web/StorageController.java添加如下代码@RequestMapping("/home")publicModelAndViewhome(HttpServletRequestrequest,HttpServletResponseresponse,Stringpath){ModelAndViewview=newModelAndView();Useruser=getSessionUser(request);path=UtilTools.converStr(path);Listlist=storage.getAllStoredList(user.getUsername(),path);view.addObject("path",path);view.addObject("search","false");view.addObject("list",list);view.setViewName("/main");view.addObject("type",0);return

view;}实现步骤14在main.jsp的table标签中添加如下代码<tbodyid="tab"><c:forEachvar="fb"items="${list}"><tr><tdstyle="top:-6px;position:relative;left:13px;"><labelclass="checkboxtable-checkboxposition"for="checkbox1"><spanclass="iconsmain-icons">

<spanclass="first-iconfui-checkbox-unchecked"></span>

<spanclass="second-iconfui-checkbox-checked"></span></span>

<inputtype="checkbox"name='check'class="main-tabinput"onclick="show()"></label></td><td><spanstyle="display:block"><c:iftest="${fb.isdirectory==true}">实现步骤15在main.jsp的table标签中添加如下代码<imgsrc="assets/images/0.png"class="objimg"><a

href="home.action?path=${fb.path}"><inputname="objimg"type="text"style="display:none"value="${}"></c:if>${}<c:iftest="${fb.isdirectory==true}"></a>实现步骤16在main.jsp的table标签中添加如下代码</c:if></span><divclass="edit-name"style="display:none;"><inputclass="box"type="text"value="${}"><aclass="sure"
