Spring統合ftpインバウンドチャネルアダプタ再帰的同期

Question

Spring統合では、ファイル（サブフォルダのファイルを含む）をftpインバウンドチャネルアダプタを使用して再帰的に同期できますか？

Answer 1

いいえ;しかし、あなたは...アウトバウンドゲートウェイとの再帰MGETとの完全なリモートディレクトリツリーを取得することができます

@SpringBootApplication 
@IntegrationComponentScan 
public class So42324318Application { 

    public static void main(String[] args) { 
     ConfigurableApplicationContext context = SpringApplication.run(So42324318Application.class, args); 
     List<File> files = context.getBean(Gateway.class).fetchFiles("foo/*"); 
     System.out.println(files); 
     context.close(); 
    } 

    @MessagingGateway(defaultRequestChannel = "fetchRecursive") 
    public interface Gateway { 

     public List<File> fetchFiles(String remoteDir); 

    } 

    @Bean 
    @ServiceActivator(inputChannel = "fetchRecursive") 
    public FtpOutboundGateway gateway() { 
     // Create a recursive MGET gateway that gets the remote directory from the payload 
     FtpOutboundGateway gateway = new FtpOutboundGateway(sessionFactory(), "mget", "payload"); 
     gateway.setOptions("-R"); 
     gateway.setLocalDirectoryExpression(new SpelExpressionParser().parseExpression("#remoteDirectory")); 
     return gateway; 
    } 

    @Bean 
    public SessionFactory<FTPFile> sessionFactory() { 
     return new CachingSessionFactory<>(ftpSF()); 
    } 

    private SessionFactory<FTPFile> ftpSF() { 
     DefaultFtpSessionFactory sf = new DefaultFtpSessionFactory(); 
     sf.setHost("10.0.0.3"); 
     sf.setUsername("ftptest"); 
     sf.setPassword("ftptest"); 
     sf.setClientMode(FTPClient.PASSIVE_LOCAL_DATA_CONNECTION_MODE); 
     return sf; 
    } 

}
