一個javaFTP的客戶端

1、文檔根源為:從網絡采集整理.word版本可編寫.支持.一個javaFTP的客戶端使用的了apache的commons-net實現批量下載,上傳,刪除等功能:import;import;import;import;import;import;import;import;import;import;import;publicclassFtpClientHandlerprivateFTPClientf=newFTPClient();privateStringhost=;privateStringusername=test;privateStringpassword=test;privateStrin

2、gr_workDirector=./;privateStringl_workDirector=./;privateStringconfig_file=./config/perties;privateStringremote_files=*;privateStringlocal_files=*;publicFtpClientHandler()throwsIOExceptionsuper();init();publicvoidinit()throwsIOException文檔根源為:從網絡采集整理.word版本可編寫.支持.FileInputStreamfis=newFileInputStream

3、(config_file);Propertiesconfig=newProperties();config.load(fis);host=config.getProperty(Boss_FTP_Url);username=config.getProperty(Username);password=config.getProperty(Password);r_workDirector=config.getProperty(Remote_workdirector);l_workDirector=config.getProperty(Local_workdirector);remote_files=

4、config.getProperty(Remote_download_files);local_files=config.getProperty(Local_upload_files);privatevoidconnection()throwsSocketException,IOExceptionf.connect(host);f.login(username,password);f.changeWorkingDirectory(r_workDirector);privatevoidclose()throwsIOExceptionif(f!=null)f.disconnect();public

5、voidDeleteFiles()throwsIOExceptionconnection();FTPListParseEngineengine=f.initiateListParsing(remote_files);FTPFilefiles=engine.getFiles();for(inti=0;i);f.dele(filesi.getName();文檔根源為:從網絡采集整理.word版本可編寫.支持.close();publicvoidDownloadFiles()throwsFileNotFoundException,IOExceptionconnection();FTPListPars

6、eEngineengine=f.initiateListParsing(remote_files);FTPFilefiles=engine.getFiles();for(inti=0;i);f.retrieveFile(filesi.getName(),newFileOutputStream(newFile(l_workDirector+filesi.getName();close();publicvoidStorFiles()throwsFileNotFoundException,IOExceptionconnection();Filefile=newFile(l_workDirector)

7、;/在此目錄中找文件BFSFileSearchsearch=newBFSFileSearch();ListfileList=search.scanFiles(file,local_files);for(inti=0;ifileList.size();i+)StringfileName=(String)fileList.get(i);f.storeFile(fileName,newFileInputStream(newFile(l_workDirector+fileName);close();文檔根源為:從網絡采集整理.word版本可編寫.支持.此中利用了深度搜尋體制來對*,?等通配符的支持:i

8、mport;import;import;import;publicclassBFSFileSearch/*paramfileName*String需要查找的文件，可含通配符如*.javaparambaseFileString欲查找的文件夾paramArrayList*fileList結果集paramcountint控制結果數目，為0，表示返回全部的般配的文件*/publicvoidscanFiles(Filebase,StringfileName,ListfileList,intcount)Queuequeue=newQueue();/實例化行列queue.put(base);/入隊while

9、(!queue.isEmpty()Filef=(File)queue.get();/if(f.exists()&f.isDirectory()出行列for(inti=0;i=count)return;fileList.add(filePath);/增添到結果集/*overwritemethodscanFilesparambaseparamfileNamereturn*/publicListscanFiles(Filebase,StringfileName)Queuequeue=newQueue();/實例化行列queue.put(base);/入隊ListfileList=newArrayLi

10、st();while(!queue.isEmpty()Filef=(File)queue.get();/出行列文檔根源為:從網絡采集整理.word版本可編寫.支持.if(f.exists()&f.isDirectory()Stringfiles=f.list();for(inti=0;ifiles.length;i+)Filef2=newFile(f,filesi);if(f2.isDirectory()/queue.put(f2);文件夾則進行列else/文件則進行般配StringfilePath=f2.getAbsolutePath();filePath=filePath.substrin

11、g(filePath.lastIndexOf(/)+1);/if(wildcardMatch(fileName,提取文件名filePath)/般配成功fileList.add(filePath);/增添到結果集returnfileList;publicbooleanwildcardMatch(Stringpattern,Stringstring)intstringLength=string.length();intstringIndex=0;for(intpatternIndex=0;patternIndexpattern.length();+patternIndex)charc=patter

12、n.charAt(patternIndex);if(c=*)while(stringIndexstringLength)returnfalse;elseif(stringIndex=stringLengthc!=string.charAt(stringIndex)returnfalse;+stringIndex;returnstringIndex=stringLength;classQueue/先進先出的行列privateVectorvector=newVector();publicvoidput(Objectobject)/vector.addElement(object);入隊publicObjectget()/出隊Objectobject=peek();if(object!=null)vector.removeElementAt(0);文檔根源為:從網絡采集整理
