B. java 實現ftp上傳如何創建文件夾

准備條件：java實現ftp上傳用到了commons-net-3.3.jar包

首先建立ftphost連接

publicbooleanconnect(Stringpath,Stringaddr,intport,Stringusername,Stringpassword){
		try{
			//FTPClientftp=newFTPHTTPClient(addr,port,username,password);
			ftp=newFTPClient();
			intreply;
			ftp.connect(addr);
			System.out.println("連接到："+addr+":"+port);
			System.out.print(ftp.getReplyString());
			reply=ftp.getReplyCode();

			if(!FTPReply.isPositiveCompletion(reply)){
				ftp.disconnect();
				System.err.println("FTP目標伺服器積極拒絕.");
				System.exit(1);
				returnfalse;
			}else{
				ftp.login(username,password);
				ftp.enterLocalPassiveMode();
				ftp.setFileType(FTPClient.BINARY_FILE_TYPE);
				ftp.changeWorkingDirectory(path);
				System.out.println("已連接："+addr+":"+port);
				returntrue;
			}
		}catch(Exceptionex){
			ex.printStackTrace();
			System.out.println(ex.getMessage());
			returnfalse;
		}
	}

然後再利用ftpclient的makeDirectory方法創建文件夾

	publicvoidcreateDir(Stringdirname){
		try{
			ftp.makeDirectory(dirname);
			System.out.println("在目標伺服器上成功建立了文件夾:"+dirname);
		}catch(Exceptionex){
			System.out.println(ex.getMessage());
		}
	}

斷開host連接

	publicvoiddisconnect(){
		try{
			ftp.disconnect();
		}catch(IOExceptione){
			e.printStackTrace();
		}
	}

最後是程序的調用方法

	publicstaticvoidmain(String[]args){
		FtpUploadTestftpupload=newFtpUploadTest();
		if(ftpupload.connect("","172.39.8.x",20,"administrator","abc@123")){
			ftpupload.createDir("/UPLOAD");
			ftpupload.disconnect();
		}
	}

C. java ftpclient怎麼傳輸多個文件

/**

* @Version1.0 Jul 27, 2008 4:31:09 PM by 崔紅保（[email protected]）創建
* @param url FTP伺服器hostname

* @param password FTP登錄密碼
* @param path FTP伺服器保存目錄

* @param input 輸入流
* @return 成功返回true，否則返回false
*/
publicstaticboolean uploadFile(String url,int port,String username, String password, String path, String filename, InputStream input) {
boolean success = false;
FTPClient ftp = new FTPClient();
try {
int reply;
ftp.connect(url, port);//連接FTP伺服器
//如果採用默認埠，可以使用ftp.connect(url)的方式直接連接FTP伺服器
ftp.login(username, password);//登錄
reply = ftp.getReplyCode();
if (!FTPReply.isPositiveCompletion(reply)) {
ftp.disconnect();
return success;
}
ftp.changeWorkingDirectory(path);
ftp.storeFile(filename, input);

input.close();
ftp.logout();
success = true;
} catch (IOException e) {
e.printStackTrace();
} finally {
if (ftp.isConnected()) {
try {
ftp.disconnect();
} catch (IOException ioe) {
}
}
}
return success;
}<pre></pre>

D. java如何實現將FTP文件轉移到另一個FTP伺服器上

你有FTPClient就比較好辦，假如你的兩台FTP伺服器分別為fs1和fs2

在本地開發代碼思路如下：

1. 通過FTPClient連接上fs1，然後下載（可以循環批量下載）到本地伺服器，保存到一個臨時目錄。

2. 下載完成後，FTPClient斷開與fs1的連接，記得必須logout。

3. 本地伺服器通過FileInputStream將剛下載到臨時目錄的文件讀進來，得到一個List<File>集合。

4. 通過FTPClient連接上fs2，循環List<File>集合，將文件上傳至fs2的特定目錄，然後清空臨時目錄，上傳完畢後，斷開fs2的連接，同樣必須logout。
   

E. 用java有一個ftp路徑地址，需要把傳送一些數據到ftp中怎樣實現

1.使用的FileZillaServer開源，安裝過後建立的本地FTP伺服器。2.使用的apache上FTP工具包，引用到工程目錄中。3.IDE，Eclipse，JDK6上傳和目錄的實現原理：對每一個層級的目錄進行判斷，是為目錄類型、還是文件類型。如果為目錄類型，採用遞歸調用方法，檢查到最底層的目錄為止結束。如果為文件類型，則調用上傳或者方法對文件進行上傳或者操作。貼出代碼：（其中有些沒有代碼，可以看看，還是很有用處的）！

F. java如何實現兩台ftp伺服器之間的文件傳輸10

�0�2我知道apache有個commons net包，其中的FTPClient類可以實現客戶端和服務之間的文件傳輸，但是我如果使用這種方式的話，就得將一台伺服器上的文件傳到我本地，再將這個文件傳到另一台伺服器上，感覺這中間多了一步操作；我想請問大家如何能不通過本機，直接操作兩台伺服器，將文件從一台伺服器傳到另一台伺服器上，如果有人知道實現方式，希望不吝賜教，謝謝了！問題補充：<div class="quote_title"suziwen 寫道</div<div class="quote_div"把JAVA程序放在其中一台FTP服務 器A上，通過A伺服器上的JAVA登錄到另一台FTP伺服器，F代碼執行文 件的上傳，下載。 / /</div / /謝謝你們的回答，你們說的這種方式我明白。
