我正在尝试使用以下java代码使用org.apache.commons.net.ftp将文件存储在pureftp服务器上
import org.apache.commons.net.ftp.FTP;
import org.apache.commons.net.ftp.FTPReply;
import org.apache.commons.net.ftp.FTPSClient;
public void upload2ndToServer(String directory) throws Exception {
LOG.debug("upload2ndToServer " + directory);
FTPSClient ftp = new FTPSClient("TLS", false);
int reply;
ftp.connect(GetConfigValue("2nd", "RemoteAddress"));
ftp.addProtocolCommandListener(new PrintCommandListener(new PrintWriter(System.out)));
reply = ftp.getReplyCode();
if (!FTPReply.isPositiveCompletion(reply)) {
ftp.disconnect();
throw new Exception("Exception in connecting to FTP Server");
}
ftp.login(GetConfigValue("2nd", "RemoteLogin"), GetConfigValue("2nd", "RemotePassword"));
LOG.debug("FTP info: " + ftp.getStatus() + " : " + " : " + ftp.getReplyString());
ftp.changeWorkingDirectory(GetConfigValue("2nd", "RemoteDirectory"));
ftp.setFileType(FTP.BINARY_FILE_TYPE);
ftp.setControlEncoding("UTF8");
ftp.execPBSZ(0);
ftp.execPROT("P");
try {
upload(new File(directory), ftp);
} catch (Exception e) {
ftp.disconnect();
LOG.info("ERROR FTP disconnected: " + e.getMessage());
}
}
public void upload(File src, FTPSClient ftp) throws IOException {
LOG.debug("upload " + src.getPath());
if (src.isDirectory()) {
LOG.debug("directory " + src.getName());
ftp.makeDirectory(src.getName());
ftp.changeWorkingDirectory(src.getName());
for (File file : src.listFiles()) {
upload(file, ftp);
}
ftp.changeToParentDirectory();
} else {
InputStream input = null;
try {
ftp.enterLocalPassiveMode();
LOG.debug("FTP info: " + ftp.getStatus() + " : " + " : " + ftp.getReplyString());
BufferedInputStream buffIn = null;
buffIn = new BufferedInputStream(new FileInputStream(src.getPath()));
boolean result = ftp.storeFile(src.getName(), buffIn);
buffIn.close();
LOG.debug(result + " stored file " + src.getName() + " code:" + ftp.getReplyCode());
LOG.debug("reply" + ftp.getReplyString());
} finally {
IOUtils.close(input);
}
}
}
正如您从日志中看到的那样，该进程登录并创建了一个目录，但是它会继续尝试在该新目录中存储一个 37KB 的文件。该过程在“150 Accepted data connection”作为响应后挂起并且未完成。

有人对如何解决此问题提出建议吗？
您能解释一下 filezilla 日志行226-Options: -a -l 的含义吗？
