无法在Spring Integration中使用基于注释的FTPInbound Adapter在文件夹之间传输/复制文件

Question

我使用以下代码使用FTP入站适配器进行文件传输，但文件不会被传输。任何关于此的线索都会非常有用。

@Bean
public IntegrationFlow ftpIn()
{


    DefaultFtpSessionFactory defSession=new DefaultFtpSessionFactory();
    defSession.setUsername("anonymous");
    defSession.setPassword("anonymous!!");
    defSession.setPort(21);
    defSession.setHost("10.47.116.158");


    File localDirectory=new File("C:\\FTP_Default");
    File remoteDirectory=new File("C:\\FilesFromServer");




    return IntegrationFlows.from(Ftp.inboundAdapter(defSession).localDirectory(localDirectory).remoteDirectory("C:\\FilesFromServer")
            .autoCreateLocalDirectory(true),
            e -> e.poller(Pollers.fixedRate(50)).autoStartup(true))
            .channel(this.inputChannel())
            .handle(System.out::println).get();



}
 @Bean
     public DirectChannel inputChannel() {
        return new DirectChannel();
    }

上述问题的解决方案是：

@Bean
public IntegrationFlow ftpIn()
{


    DefaultFtpSessionFactory defSession=new DefaultFtpSessionFactory();
    defSession.setUsername(userId);
    defSession.setPassword(password);
    defSession.setPort(port);
    defSession.setHost(host);
    defSession.setClientMode(2);
    **String remoteDirectory=DefaultFtpSessionFactory.DEFAULT_REMOTE_WORKING_DIRECTORY;**



    File localDirectory=new File("C:\\FilesFromServer");




    return IntegrationFlows.from(Ftp.inboundAdapter(defSession).localDirectory(localDirectory).remoteDirectory(remoteDirectory)
            .autoCreateLocalDirectory(true),
            e -> e.poller(Pollers.fixedRate(50)))
            .channel(this.inputChannel())
            .handle(m -> System.out.println(m.getPayload())).get();


}
 @Bean
     public DirectChannel inputChannel() {
        return new DirectChannel();
    }
