开发文件复制黏贴功能

文件复制功能一、目录21.技术原理2.效果图预览3.实现步骤4.功能验证测试二、技术原理3（1）视图层：显示复制文件对话框（2）控制层：接收视图层的消息，向服务层发送文件复制参数，并将服务层返回的结果发送到视图层（3）服务层：调用swift服务对文件进行复制和粘贴，并将结果返回给控制层三、效果预览图4四、步骤实现5在cn/edu/sict/cloud/storage/service/SwiftStorageService.java添加如下代码public

booleancopyfile(Stringusername,List<Map<String,Object>>list){for(Map<String,Object>map:list){Stringpath=(String)map.get("path");Stringnewpath=(String)map.get("newpath");Stringname=(String)map.get("name");StringtisDir=(String)map.get("isDir");boolean

isDir="true".equals(tisDir)?true:false;SwiftDFSswiftdfs=newSwiftDFS();if(isDir){swiftdfs.copyDir(username+"/"+path,username+"/"+newpath);}else{swiftdfs.copyFile(username+"/"+path,username+"/"+newpath+name);}}return

true;}四、步骤实现6在cn/edu/sict/cloud/storage/service/SwiftStorageService.java添加如下代码/***取得路径下的所有文件夹*/publicListgetAllStoredDirectoryList(Stringusername,Stringpath,Stringupath){SwiftDFSswiftdfs=newSwiftDFS();Listlist=newArrayList();Stringup=null;if(path==null||path.equals("")){

len=rootpath.length();Stringpath=rmpath;Stringnewpath=rnpath;Stringname=rmpath.split("/")[rmpath.split("/").length-1];if(path.equals(newpath)){return

false;}this.copy(rootpath,rootpath,path,newpath+name+"/");copydirfile(rootpath,path,newpath,name,path);return

true;}四、步骤实现10在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代码private

voidcopydirfile(Stringrootpath,Stringpath,Stringnewpath,Stringname,Stringepath){List<?extendsSwiftObject>objs=this.list(rootpath,path);for(SwiftObjectswiftObject:objs){if(swiftObject.isDirectory()){Stringcpath=swiftObject.getName();Stringtpath=cpath.substring(path.length());Stringtnewpath=newpath+name+"/"+tpath;//strs[1];this.copy(rootpath,rootpath,cpath,tnewpath);copydirfile(rootpath,path,newpath,name,cpath);}else{Stringtemppath=swiftObject.getName();if(temppath.endsWith("/")){continue;}Stringtpath=temppath.substring(path.length());Stringtnewpath=newpath+name+"/"+tpath;//strs[1];this.copy(rootpath,rootpath,temppath,tnewpath);}}}四、步骤实现11在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代码public

booleancopyFile(Stringrpath,Stringrnewpath){Mapmappath=getSplitPath(rpath);Stringpath=mappath.get("path").toString();StringrootPath=mappath.get("rootPath").toString();Mapnmappath=getSplitPath(rnewpath);Stringnpath=nmappath.get("path").toString();Stringnrootpath=nmappath.get("rootPath").toString();boolean

isexist=this.isexist(nrootpath,npath);if(isexist){this.copy(rootPath,nrootpath,path,npath);return

true;}return

false;}四、步骤实现12在cn/edu/sict/cloud/storage/Web/StorageController.java添加如下代码@RequestMapping("/copyfile")@ResponseBodypublicObjectcopyfile(HttpServletRequestrequest,HttpServletResponseresponse,@RequestBodyList<Map<String,Object>>list){Useruser=getSessionUser(request);boolean

flag=false;flag=storage.copyfile(user.getUsername(),list);return

newMessageBean(flag,flag?Constants.SUCCESS_8:Constants.ERROR_9);}四、步骤实现13在cn/edu/sict/cloud/storage/Web/StorageController.java添加如下代码@RequestMapping("/homedir")@ResponseBodypublicObjecthomedir(HttpServletRequestrequest,HttpServletResponseresponse,Stringpath){Useruser=getSessionUser(request);Stringupath=request.getSession().getServletContext().getRealPath("/");Listlist=storage.getAllStoredDirectoryList(user.getUsername(),path,upath);return
