我需要通过 sftp 连接到 ftp 服务器。我通过 ftp 和 ftps 成功连接了骆驼。

public static RouteBuilder getRouteBuilderSFTPS() {
        return new RouteBuilder() {
            public void configure() {
                from("sftp://666.66.666.66:22/POLP-FROAKS?fileName=testMsg.txt&username=POLP-FROAKS&password=pass&strictHostKeyChecking=no&ciphers=blowfish-cbc,aes128-ctr,aes128-cbc,3des-ctr,3des-cbc,aes192-cbc,aes256-cbc").
                to("file://target/test-reports667");
            }
        };
    }

我得到响应 org.apache.camel.component.file.GenericFileOperationFailedException: Cannot change directory to: POLP-FROAKS

我有相同的代码，但没有骆驼，它可以工作。骆驼版有什么问题？我也有点困惑为什么服务器不问我关于私钥的问题？

更新：

我正在尝试添加私钥：

JSch.setLogger(new MyJschLogger());
            JSch ssh = new JSch();

            final byte[] privateKey = getPrivateKeyAsByteStream(privateKeyPath);
            final byte[] passPrivateKey = "".getBytes();
            //TODO DB: invalid private key. If not use private key than we can download file
            ssh.addIdentity(username, privateKey, null, passPrivateKey);

            session = ssh.getSession(username, server, port);
            session.setPassword(password);
            session.setConfig("StrictHostKeyChecking", "no");

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

            final Vector files = sftp.ls(".");
            Iterator itFiles = files.iterator();
            while (itFiles.hasNext()) {
                System.out.println("Index: " + itFiles.next());
            }

            sftp.get(remoteFile, localFile);
            sftp.exit();

已读取密钥，但出现错误：
