FTP funktioniert nicht in Apache Kamel

Question

Ich versuchte Apache Kamel in Beispielen für ftp gebaut und mit springboot integrieren. Wenn ich keine ausführe, erhalte ich eine Fehlermeldung, nicht den Download der Datei. Im Folgenden finden Sie das Code-Snippet und die Protokolle. Aus den Logs konnte ich sehen, dass der Server erfolgreich verbunden ist, aber ich kann die Datei nicht im Ordner /tmp/ sehen.

Und der Code:

@SpringBootApplication 
public class MySpringBootRouter extends FatJarRouter { 

    @Override 
    public void configure() throws Exception{ 

     // configure properties component 
     PropertiesComponent pc = getContext().getComponent("properties", PropertiesComponent.class); 
     pc.setLocation("classpath:ftp.properties"); 

     // lets shutdown faster in case of in-flight messages stack up 
     getContext().getShutdownStrategy().setTimeout(10); 

     from("sftp://<mylinuxserver>:22/tmp/sample.txt?username=abc&password=123") 
      .to("file:/tmp/sample.txt") 
      .log("Downloaded file ${file:name} complete."); 

     System.out.println("*********************************************************************************"); 
     // System.out.println("Camel will route files from the FTP server: " 
     //  + getContext().resolvePropertyPlaceholders("{{ftp.server}}") + " to the target/download directory."); 
     System.out.println("You can configure the location of the ftp server in the src/main/resources/ftp.properties file."); 
     System.out.println("Use ctrl + c to stop this application."); 
     System.out.println("*********************************************************************************"); 
    } 
}

Sie könnten versuchen, mit Stepwise Option und/oder jschLoggingLevel zu TRACE

auch Filezilla zur Überprüfung mit einem App.
