问题描述

我正在尝试使用localhost配置在SFTP上进行连接，但是出现以下错误.但是，当我在FilleZilla上使用相同的配置时，它可以完美运行...

I'm trying to connect on SFTP using localhost configurations but I get the following error. But when I use the same configurations on FilleZilla it works perfect...

在FilleZilla服务器上:

At FilleZilla server:

(000017)06/08/2019 09:26:20 - (not logged in) (127.0.0.1)> Connected on port 21, sending welcome message...

这是Java中的错误:

Here is the error in Java:

com.jcraft.jsch.JSchException: connection is closed by foreign host
    at com.jcraft.jsch.Session.connect(Session.java:269)
    at com.jcraft.jsch.Session.connect(Session.java:183)
    at br.com.wasys.nps.service.SftpService.test(SftpService.java:26)

这是我的Java代码:

Here is my Java code:

JSch jsch = new JSch();

Session session = jsch.getSession("test", "localhost", 21);
session.setConfig("StrictHostKeyChecking", "no");
session.setPassword("root");
session.connect();

ChannelSftp channel = (ChannelSftp) session.openChannel("sftp");
channel.connect();
ChannelSftp sftpChannel = channel;

推荐答案

FileZilla是FTP服务器，而不是SFTP服务器.

FileZilla is FTP server, not SFTP server.

JSch是SFTP客户端.

JSch is SFTP client.

您不能使用JSch连接到FileZilla服务器.

You cannot use JSch to connect to FileZilla server.

您必须使用FTP库，例如 Apache Commont Net FTPClient .

You have to use an FTP library, like Apache Commont Net FTPClient.
