开发重命名功能

文件重命名功能一、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：显示文件重命名的输入框（2）控制层：接收视图层的消息，向服务层发送文件和文件夹重命名参数，并将服务层返回的结果发送到视图层（3）服务层：调用swift服务对文件重命名，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

booleancreateDir(Stringusername,Stringpath,Stringname){SwiftDFSswiftdfs=newSwiftDFS();path+=name+"/";swiftdfs.createDir(username,path);return

true;}四、步骤实现6在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代码private

voidrenamedirfile(StringrootPath,Stringpath,StringnewPath){this.copy(rootPath,rootPath,path,newPath);this.delete(rootPath,path);}四、步骤实现7在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代码private

voidrenamecdirfile(Stringrootpath,Stringcpath,Stringpath,Stringnewpath){Stringstr1[]=newpath.split("/");Stringstr2[]=cpath.split("/");Stringstrpath="";for(int

i=0;i<str2.length;i++){if(i<str1.length){strpath+=str1[i]+"/";}else{strpath+=str2[i]+"/";}}this.copy(rootpath,rootpath,cpath,strpath);this.delete(rootpath,cpath);}四、步骤实现8在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代码public

booleanrenameFile(Stringrpath,Stringname){Mapmappath=getSplitPath(rpath);Stringpath=mappath.get("path").toString();Stringrootpath=mappath.get("rootPath").toString();Stringnewpath="";Stringstr[]=path.split("/");for(int

i=0;i<str.length;i++){if(i==str.length-1){newpath+=name;}else{newpath+=str[i]+"/";}}this.copy(rootpath,rootpath,path,newpath);this.delete(rootpath,path);return

true;}四、步骤实现9在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代码private

voidrenamecfilefile(StringrootPath,Stringcpath,Stringpath,StringnewPath){Stringstr1[]=newPath.split("/");Stringstr2[]=cpath.split("/");Stringstrpath="";for(int

i=0;i<str2.length;i++){if(i<str1.length){strpath+=str1[i]+"/";}else

if(i==str2.length-1){strpath+=str2[i];}else{strpath+=str2[i]+"/";}}this.copy(rootPath,rootPath,cpath,strpath);this.delete(rootPath,cpath);}四、步骤实现10在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代码private

booleanisexist(Stringrootpath,Stringnewpath){List<?extendsSwiftObject>objs=this.list(rootpath);for(SwiftObjectswiftObject:objs){if(swiftObject.getName().equals(newpath)){return

false;}}return

true;}private

voidcopy(StringsrcContainer,StringdestContainer,StringsrcPath,StringdestPath){ObjectLocationsrcLocation=ObjectLocation.create(srcContainer,srcPath);ObjectLocationdestLocation=ObjectLocation.create(destContainer,destPath);os.objectStorage().objects().copy(srcLocation,destLocation);}private

voiddelete(StringrootPath,StringsrcPath){os.objectStorage().objects().delete(rootPath,srcPath);}四、步骤实现11在cn/edu/sict/cloud/storage/service/SwiftStorageService.java添加如下代码public

booleanupdatefile(Stringusername,Stringpath,Stringname,boolean

isdir){SwiftDFSswiftdfs=newSwiftDFS();if(isdir){return

swiftdfs.renameDir(username+"/"+path,name);}else{return

swiftdfs.renameFile(username+"/"+path,name);}}四、步骤实现12在cn/edu/sict/cloud/storage/Web/StorageController.java添加如下代码@RequestMapping("/updatefile")@ResponseBodypublicObjectupdatefile(HttpServletRequestrequest,HttpServletResponseresponse,Stringpath,Stringname,boolean

isDir){Useruser=getSessionUser(request);boolean

flag=storage.updatefile(user.getUsername(),path,name,isDir);return

newMessageBean(flag,flag?Constants.SUCCESS_7:(isDir?Constants.ERROR_4:Constants.ERROR_5));四、步骤实现13用户选择某一文件触发单击事件show()：functionshow(){varobjTable=document.getElementById("tab");for(vari=0;i<objTable.rows.length;i++){varcheckbox=objTable.rows[i].childNodes[1].childNodes[0].childNodes[5];if(checkbox.checked==true){document.getElementById("delete").style.display="block";document.getElementById("download").style.display="block";document.getElementById("rename").style.display="block";document.getElementById("move").style.display="block";document.getElementById("copy").style.display="block";document.getElementById("selectColumn").style.display="block";break;}else{document.getElementById("delete").style.display="none";document.getElementById("download").style.display="none";document.getElementById("rename").style.display="none";document.getElementById("move").style.display="none";document.getElementById("copy").style.display="none";document.getElementById("selectColumn").style.display="none";}}}四、步骤实现14为重命名按钮添加单击事件rename()，并在js中添加如下代码:functionrenanme(){varnum=0;varobjTable=document.getElementById("tab");for(vary=0;y<objTable.rows.length;y++){varcheckbox=objTable.rows[y].childNodes[1].childNodes[0].childNodes[5];if(checkbox.checked==true){if(num<1){varrenamebox=checkbox.parentNode.parentNode.parentNode.childNodes[3].childNodes[2];varrenametxt=checkbox.parentNode.parentNode.parentNode.childNodes[3].childNodes[0];renametxt.style.display="none";renamebox.style.display="block";num+=1;}else{alert('不能同时重命名两个或两个以上文件');location.reload();break;}}}}四、步骤实现15在js中添加如下代码，获取用户输入的文件名、文件路径，判断是否为文件夹functionsure(){varobjTable=document.getElementById("tab");for(vary=0;y<objTable.rows.length;y++){varcheckbox=objTable.rows[y].childNodes[1].childNodes[0].childNodes[5];if(checkbox.checked==true){varchangename=checkbox.parentNode.parentNode.parentNode.childN
