Apache Camel SFTP:“JSCHEException:无效的私钥：[B@7c033a39“使用OpenSSH私钥

Question

我试图连接到一个sftp服务器与一个新的私钥，开始与BEGIN OPENSSH PRIVATE KEY（旧版本开始与BEGIN RSA PRIVATE KEY）。

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

当连接Camel SFTP（版本3.10）时，我得到一个错误

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-键很好。

我从这个答案中发现错误是由过时的Jsch版本引起的——但这应该在3.10中针对驼峰SSH进行修复https://issues.apache.org/jira/browse/CAMEL-16554，但我想这不会影响sftp？

我如何连接？

有sftp配置来设置“密码”和“密钥交换协议”——这些相关吗？

要替换由camel ftp starter引入的Jsch库，可以使用如下所示的exclude标记：

    <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。
