有没有办法通过org.apache.commons.net.ftp.FTPClient
实现安全的FTP?使用org.apache.commons.net.ftp.FTPClient保护FTP
如果不是,还有什么其他Java选项?

您可以使用org.apache.commons.net.ftp。 FTPSClient而不是org.apache.commons.net.ftp。 FTPClient有安全的FTP http://commons.apache.org/proper/commons-net/apidocs/org/apache/commons/net/ftp/FTPSClient.html
如何努力Apache的骆驼,
Apache FTPClient目前不支持SFTP。但是,您可以使用JSch - Java Secure Channel。
Onkar Joshi更详细地介绍了用于在Java中进行FTP,SFTP,FTPS文件传输的库。
使用JSch与SFTP传输文件的例子如下:
...
private static final Logger logger = Logger.getLogger(YourClass.class.getName());
public boolean sendDataViaSFTP(String contents) throws Exception {
String hostname = "<FTP hostname/IP>";
String username = "<FTP username>";
String password = "<FTP password>";
String remoteDirectory = "<FTP remote directory>";
int ftpPort = 22;
logger.info("*** Creating FTP session. ***");
JSch jsch = new JSch();
Session session = null;
Channel channel = null;
ChannelSftp c = null;
//Now connect and SFTP to the SFTP Server
try {
//Create a session sending through our username and password
session = jsch.getSession(username, hostname, ftpPort);
logger.info("*** FTP Session created. ***");
session.setPassword(password);
//Security.addProvider(new com.sun.crypto.provider.SunJCE());
//Setup Strict HostKeyChecking to no so we dont get the
//unknown host key exception
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);
session.connect();
logger.info("*** Session connected. ***");
//Open the SFTP channel
logger.info("*** Opening FTP Channel. ***");
channel = session.openChannel("sftp");
channel.connect();
c = (ChannelSftp) channel;
//Change to the remote directory
logger.info("*** Changing to FTP remote dir: " + remoteDirectory + " ***");
c.cd(remoteDirectory);
//Send the file we generated
try {
String filename = "myfile.txt";
logger.info("*** Storing file as remote filename: " + filename + " ***");
ByteArrayInputStream bis = new ByteArrayInputStream(contents.getBytes());
c.put(bis, filename);
return true;
} catch (Exception e) {
logger.info("*** Storing remote file failed. " + e.toString() + " ***");
throw e;
}
} catch (Exception e) {
logger.info("*** Unable to connect to FTP server. " + e.toString() + " ***");
throw e;
} finally {
//
//Disconnect from the FTP server
//
try {
if(session != null)
session.disconnect();
if(channel != null)
channel.disconnect();
if(c != null)
c.quit();
} catch (Exception exc) {
logger.severe("*** Unable to disconnect from FTP server. " + exc.toString()+" ***");
}
logger.info("*** SFTP Process Complete. ***");
}
}
...
首先,确保你理解FTPS(安全FTP)和SFTP之间的差异:
FTPS versus SFTP versus SCP
如果您需要FTPS(安全FTP),你可以使用FTPSClient
而不是从FTPClient
阿帕奇百科全书库:
https://commons.apache.org/proper/commons-net/apidocs/org/apache/commons/net/ftp/FTPSClient.html
如果需要SFTP,请参阅:

你发现了什么了吗? – Rob
有没有原因你不能SSH?如果不是,请尝试Apache Mina或Jsch – amphibient
将它切换到“FTPSClient”的子类是什么? –
