英文:
Java FTPSClient TLS FTP connection to pureftp server hangs on storeFile
问题
以下是您提供的代码部分的翻译：
我尝试使用以下Java代码将文件存储在pureftp服务器上，使用org.apache.commons.net.ftp库。
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 {
// ...（代码的其余部分）
}
public void upload(File src, FTPSClient ftp) throws IOException {
// ...（代码的其余部分）
}
关于日志部分，这是您的日志内容：
如您所见，此过程登录并创建一个目录，但在尝试将一个37KB大小的文件存储在该新目录中时挂起。进程在“150 Accepted data connection”响应之后挂起，无法完成。

英文:
I'm trying to store a file on a pureftp server using the following java code using org.apache.commons.net.ftp
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);
}
}
}
As you can see from the log, the process logs in and creates a directory, however it then hangs on trying to store a 37KB file in that new directory. The process hangs after '150 Accepted data connection' as a response and does not complete.

Does anyone have a suggestion as how to resolve this issue?
Can you explain what the filezilla log line 226-Options: -a -l means?

原来，如果我将依赖关系从
<dependency>
<groupId>commons-net</groupId>
<artifactId>commons-net</artifactId>
<version>3.7</version>
切换到
<dependency>
<groupId>commons-net</groupId>
<artifactId>commons-net</artifactId>
<version>3.6</version>
然后，它按预期工作。
英文:
It turns out that if I switch the dependency from
<dependency>
<groupId>commons-net</groupId>
<artifactId>commons-net</artifactId>
<version>3.7</version>
</dependency>
to
<dependency>
<groupId>commons-net</groupId>
<artifactId>commons-net</artifactId>
<version>3.6</version>
</dependency>
It then works as expected.
