I am trying to do a file upload using Spring Integration and i am stuck at the below error. My Private keys are perfectly fine though. What can be the problem area in this case?
If I run the sftp -i .....command with the same private key it works
I have defined a rest controller which invokes the gateway
gateway.uploadFile(file);
The Upload Config is as simple as this
@Bean
public DefaultSftpSessionFactory gimmeFactory(){
DefaultSftpSessionFactory factory = new DefaultSftpSessionFactory(true);
factory.setHost(sftpHost);
factory.setPort(sftpPort);
factory.setUser(sftpUser);
if (sftpPrivateKey != null) {
factory.setPrivateKey(sftpPrivateKey);
// factory.setPrivateKeyPassphrase(sftpPrivateKeyPassphrase);
} else {
factory.setPassword(sftpPasword);
}
factory.setAllowUnknownKeys(true);
return (factory);
}
@Bean
@ServiceActivator(inputChannel = "uploadfile")
MessageHandler uploadHandler(DefaultSftpSessionFactory factory){
SftpMessageHandler messageHandler = new SftpMessageHandler(factory);
messageHandler.setRemoteDirectoryExpression(new LiteralExpression("/upload/topsecret"));
messageHandler.setFileNameGenerator(message -> String.format("mytextfile_%s.txt", LocalDateTime.now()));
return messageHandler;
}
The Exception i get is below
