云存储文件删除功能

云存储文件删除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：显示删除对话框（2）控制层：接收视图层的消息，向服务层发送文件搜索参数，并将服务层返回的结果发送到视图层（3）服务层：根据关键词搜索文件，将符合搜索条件的文件封装到集合中返回给控制层功能描述4实现步骤5在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代码public

voiddeleteFile(StringrootPath,StringsrcPath,Stringname,boolean

isDir){if(isDir){//删除文件夹this.deletefiles(rootPath,srcPath,name+"/");//删除文件夹中的文件this.deletedirfile(rootPath,srcPath,name+"/");}else{this.deletefiles(rootPath,srcPath,name);}}实现步骤6在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代码public

voiddeletefiles(StringrootPath,StringsrcPath,StringdestPath){//设置元数据boolean

flag=this.setMetadata(rootPath,srcPath);if(!flag){System.out.println("********重要：设置Metadata失败name-->"+srcPath);}//复制到回收站this.copy(rootPath,Constants.GARBAGE_PREFIX+rootPath,srcPath,destPath);//删除this.delete(rootPath,srcPath);}实现步骤7在cn/edu/sict/cloud/storage/sh/SwiftDFS.java添加如下代码private

voiddeletedirfile(StringrootPath,Stringpath,StringdestPath){List<?extendsSwiftObject>list=this.list(rootPath,path);for(SwiftObjectso:list){StringfilePath=so.getName();StringfileName=this.getName(filePath);if(this.isDirectory(filePath)){//文件夹//删除文件夹到回收站this.deletefiles(rootPath,filePath,destPath+fileName+"/");//删除文件夹下的文件deletedirfile(rootPath,filePath,destPath+fileName+"/");}else{//文件//删除文件到回收站this.deletefiles(rootPath,filePath,destPath+fileName);}}}实现步骤8在cn/edu/sict/cloud/storage/service/SwiftStorageService.java添加如下代码public

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

isDir="true".equals(tisDir)?true:false;SwiftDFSswiftdfs=newSwiftDFS();swiftdfs.deleteFile(user.getUsername(),path,name,isDir);}}实现步骤9在cn/edu/sict/cloud/storage/Web/StorageController.java添加如下代码@RequestMapping("/deletefiles")@ResponseBodypublicObjectdeletefiles(HttpServletRequestrequest,HttpServletResponseresponse,@RequestBodyList<Map<String,Object>>list){Useruser=getSessionUser(request);storage.deletefiles(user,list);return

newMessageBean(true,Constants.SUCCESS_5);}实现步骤10给删除按钮添加单击事件deletefile()，并实现删除功能functiondeletefile(){if(confirm("你确定要删除所选文件吗？")){varobjTable=document.getElementById("tab");vardata='[';for(vary=0;y<objTable.rows.length;y++){varcheckbox=objTable.rows[y].childNodes[1].childNodes[0].childNodes[5];if(checkbox.checked==true){varpath=checkbox.parentNode.parentNode.parentNode.childNodes[5].innerHTML;path=decodeURIComponent(path);vartd3=实现步骤11给删除按钮添加单击事件deletefile()，并实现删除功能checkbox.parentNode.parentNode.parentNode.childNodes[3];varimgpic=td3.getElementsByTagName("img");if(imgpic.length>0){isDir=true;varnames=td3.childNodes[0].childNodes[3].childNodes[0]varname=$(names).val();}else{isDir=false;varnames=td3.childNodes[0].childNodes[0]varname=$(names).text();}实现步骤12给删除按钮添加单击事件deletefile()，并实现删除功能data+='{"path":"'+path+'","name":"'+name+'","isDir":"'+isDir+'"}';if(y<(objTable.rows.length-1)){data+=',';}}}data+=']';vardata=eval('('+data+')');实现步骤13给删除按钮添加单击事件deletefile()，并实现删除功能$.ajax({url:"deletefiles.action",type
