当我尝试使用Apache Camel连接到由业务合作伙伴控制的SFTP主机时，我面临一个问题。我已经创建了一个ssh公共/私人密钥对，他们已经在他们的服务器上安装了公钥，并通过fileZilla和shell sftp连接，没有任何问题。但是当我尝试连接apache Camel时，我收到一个错误:验证方法"publickey,password"失败。我知道Camel中的jsch库有问题，但我已经升级到Camel 3.19版本，并且根据依赖树，可以通过./gradlew查看依赖，我使用jsch 'mwiede' 0.2.1版本的分支
我试图连接的SFTP服务器显然是相当旧的，但我没有影响。当使用shell sftp命令时，有必要使用选项'-oHostKeyAlgorithms=+ssh-dss'，但之后它的工作没有问题。
我在IntelliJ的MacOS上本地运行它-使用springboot 2.6.7和java 17骆驼路线是这样的
public void configure() {
String privateKeyString = Files.readString(Path.of("/Users/jaan/.ssh/id_rsa_cloud-integration_test"), StandardCharsets.UTF_8);
getCamelContext().getRegistry().bind("myPrivateKey", privateKeyString.getBytes(StandardCharsets.UTF_8));
from(aws2S3(bucketId + "?amazonS3Client=#s3Client" + awsGetObjectUriParams))
.choice()
.when(body().isNull())
.log("Looking for files in S3 bucket - but found none")
.otherwise()
.log("Found file in S3 [${headers.CamelAwsS3Key}]")
.process(exchange -> {
exchange.getIn().setHeader("CamelAwsS3BucketDestinationName", bucketId);
exchange.getIn().setHeader("CamelAwsS3DestinationKey", generateFileName(exchange));
log.info("Uploading file to S3 bucket [{}] and prefix [{}]", bucketId, exchange.getIn().getHeader("CamelAwsS3DestinationKey"));
})
.to(aws2S3(bucketId + "?amazonS3Client=#s3Client&operation=copyObject"))
.to(sftp(host+":22/test?maximumReconnectAttempts=1")
.binary(true)
.privateKey("#myPrivateKey")
.username(sshUserName)
.jschLoggingLevel("TRACE")
.serverHostKeys("ssh-dss")
.knownHostsFile("/Users/jka/.ssh/known_hosts")
我还尝试简单地将ssh私钥作为字符串复制到路由中。我收到的堆栈跟踪在

我希望我能得到一些帮助，使这项工作，避免被迫尝试实现它在纯java与sftp库
关于这个问题:使用"rsa-sha2-512"对libssh服务器执行JSch操作失败
解决方案是设置两个属性
.serverHostKeys("ssh-dss")
.publicKeyAcceptedAlgorithms("ssh-rsa")
然后成功了
