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

Question

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

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

当连接Camel SFTP(3.10版(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——密钥很好。

我从这个答案中发现，错误是由过时的Jsch版本引起的，但这本应在3.10中为Camel SSH修复https://issues.apache.org/jira/browse/CAMEL-16554，但我想这不会影响sftp？

如何连接？

有sftp配置来设置"ciphers"one_answers"keyExchangeProtocols"-这些相关吗？

依赖项

在项目pom我有

• org.apache.cocamel.springboot:ccamel ftp启动器

要替换由camelftp-starter引入的Jsch库，可以使用exclude标记，如下所示：

<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>

请确保没有其他依赖项拉取jcraft.jsch工件。
