apache camelでFTPが動作しない

Question

私はftpのサンプルで構築されたapache camelを試していて、springbootと組み込みました。どちらも実行していないときは、ファイルのダウンロードではなくエラーメッセージが表示されます。以下はコードスニペットとログです。ログから、サーバーが正常に接続されているのを確認できましたが、/tmp/フォルダにファイルが表示されません。

とコード：

@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("*********************************************************************************"); 
    } 
}

あなたもアプリを使用して検証のためにFilezillaのを使用してTRACE

に Stepwiseオプション および/または jschLoggingLevelを使用してみてください。
