Apache Camel SFTP: "JSchException: invalid privatekey: [B@7c033a39" with OpenSSH private key

Question

我正在尝试使用以 BEGIN OPENSSH PRIVATE KEY 开头的“新”私钥（“旧”版本以 BEGIN RSA PRIVATE KEY 开头）连接到 sftp 服务器。

-----BEGIN OPENSSH PRIVATE KEY-----
...
-----END OPENSSH PRIVATE KEY-----

使用 Camel SFTP（3.10 版）连接时出现错误

org.apache.camel.component.file.GenericFileOperationFailedException: Cannot connect to sftp://username1@localhost:55040
...
Caused by: com.jcraft.jsch.JSchException: invalid privatekey: [B@7c033a39

如果我在命令行上连接，它会按预期工作 - 密钥很好。

我从this answer 发现该错误是由过时的 Jsch 版本引起的——但这应该在 3.10 https://issues.apache.org/jira/browse/CAMEL-16554 中为 Camel SSH 修复，但我想这不会影响 sftp？

如何连接？

sftp config 可以设置“密码”和“密钥交换协议” - 这些是否相关？

要替换camel-ftp-starter引入的Jsch库，可以使用exclude标签，如下：

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <!-- First define the library of jsch fork -->
        <dependency>
            <groupId>com.github.mwiede</groupId>
            <artifactId>jsch</artifactId>
            <version>0.1.63</version>
        </dependency>
        <dependency>
            <groupId>org.apache.camel.springboot</groupId>
            <artifactId>camel-ftp-starter</artifactId>
            <version>3.9.0</version>
            <!-- exclude original jsch -->
            <exclusions>
                <exclusion>
                    <artifactId>jsch</artifactId>
                    <groupId>com.jcraft</groupId>
                </exclusion>
            </exclusions>
        </dependency>
    </dependencies>

确保没有其他依赖项拉动 jcraft.jsch 工件。
