如何在使用java配置从SFTP服务器获取文件后关闭入站通道适配器

Question

您好我很新，春天尝试使用SFTP入站通道适配器从sftp服务器获取文件，但无法关闭适配器，我尝试使用下面的代码片段，但Main不会重新启动入站适配器和所以adapter.start（）和adapter.stop（）;不工作。请提供关闭InboundChannelAdapter的任何工作示例。

public SftpInboundFileSynchronizer sftpInboundFileSynchronizer() {
   SftpInboundFileSynchronizer fileSynchronizer = new SftpInboundFileSynchronizer(sftpSessionFactory());
   fileSynchronizer.setDeleteRemoteFiles(false);
   fileSynchronizer.setRemoteDirectory(sftpFolder);
   fileSynchronizer.setFilter(new SftpSimplePatternFileListFilter("*.pdf"));
   return fileSynchronizer;

}

@Bean
@InboundChannelAdapter(channel = "stream",poller = @Poller(fixedDelay ="5000",maxMessagesPerPoll = "1"),autoStartup="false")
public MessageSource<File> sftpMessageSource() {
   SftpInboundFileSynchronizingMessageSource source = new SftpInboundFileSynchronizingMessageSource(
           sftpInboundFileSynchronizer());
   source.setLocalDirectory(new File("ftp-inbound"));
   source.setAutoCreateLocalDirectory(true);
   source.setLocalFilter(new AcceptOnceFileListFilter<File>());
   return source;

}

@Bean
@Transformer(inputChannel = "stream", outputChannel = "data")
public org.springframework.integration.transformer.Transformer transformer()  {
   return new StreamTransformer();

}

@Bean
@ServiceActivator(inputChannel = "stream")
public MessageHandler handler() {

   return new MessageHandler() {

      @Override
         public void handleMessage(Message<?> message) throws MessagingException {
            System.out.println("payload"+ message.getPayload());
            //System.out.println(""+message.);

         }

   };
}

@Bean
@ServiceActivator(inputChannel = "controlBusChannel")
public ExpressionControlBusFactoryBean controlBus() throws Exception {
    ExpressionControlBusFactoryBean controlBus = new ExpressionControlBusFactoryBean();
    return controlBus;
}
