使用Spring Integration FTP适配器将文件上载到服务器的注释配置

我无法使用基于注释的Spring Integration FTP Adapter配置将文件上传到服务器。我使用的代码是:

    @SuppressWarnings({ "unchecked", "rawtypes" })
@Bean
public IntegrationFlow ftpOut()
{


    DefaultFtpSessionFactory defSession=new DefaultFtpSessionFactory();
    defSession.setUsername("chh7kor");
    defSession.setPassword("Geetansh71!!");
    defSession.setPort(21);
    defSession.setHost("10.47.116.158");
    String remoteDirectory=DefaultFtpSessionFactory.DEFAULT_REMOTE_WORKING_DIRECTORY;


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

    return IntegrationFlows.from(Ftp.outboundAdapter(defSession, FileExistsMode.REPLACE).remoteDirectory(remoteDirectory)).get();



}

 @Bean
 public MessageChannel outputChannel() 
 {
     File f=new File(PATH_FOR_FILES_FROM_SERVER);
        File[] allSubFiles=f.listFiles();

        DirectChannel dC=new DirectChannel(); 

     for(File iterateFiles:allSubFiles)                    
        {
        final Message<File> messageFile = MessageBuilder.withPayload(iterateFiles).build();
          dC.send(messageFile);



        }
     return dC;

}

我正在尝试从本地文件夹中读取文件并将其推送到频道,但IntegrationFlow不允许我将频道附加到它。请告知如何实现相同,因为此片段没有帮助。

您似乎完全误解了Spring Java配置。 @Bean用于定义bean - 您不应该像在for循环中那样发送消息 - 应用程序上下文尚未准备好接受消息,此时它只是定义bean。

您还应将会话工厂配置为@Bean - 不在集成流@Bean中声明它。

最后,使用出站适配器启动流程毫无意义;你需要......

@Bean
public IntegrationFlow ftpOut() {
    String remoteDirectory=DefaultFtpSessionFactory.DEFAULT_REMOTE_WORKING_DIRECTORY;
    File localDirectory=new File("C:\\FTP_Default");

    return IntegrationFlows.from(outputChannel())
         .handle(Ftp.outboundAdapter(defSession, FileExistsMode.REPLACE).remoteDirectory(remoteDirectory)))
         .get();
}

然后,在创建上下文后,将消息发送到输出通道。

人们对上述问题的参考的一个工作实例是:

@Bean
public DefaultFtpSessionFactory sessionFactory()
{
    DefaultFtpSessionFactory defSession=new DefaultFtpSessionFactory();
    defSession.setUsername("chh7kor");
    defSession.setPassword("Geetansh71!!");
    defSession.setPort(21);
    defSession.setHost("10.47.116.158");

    return defSession;
}


@Bean
public IntegrationFlow ftpOut()
{


    String remoteDirectory=sessionFactory().DEFAULT_REMOTE_WORKING_DIRECTORY;


        return IntegrationFlows.from(messageChannel())
             .handle(Ftp.outboundAdapter(sessionFactory(), FileExistsMode.REPLACE).remoteDirectory(remoteDirectory+"/F").autoCreateDirectory(true))
             .get();


}

public static void main(String args[])
{
File f=new File(PATH_FOR_FILES_FROM_SERVER);
    File[] allSubFiles=f.listFiles();
    for (File file : allSubFiles) {
        if(file.isDirectory())
        {
            System.out.println(file.getAbsolutePath()+" is directory");
            //Steps for directory
        }
        else
        {
        System.out.println(file.getAbsolutePath()+" is file");
            //steps for files
        }
    }

    PollableChannel pC=ctx.getBean("pollableChannel", PollableChannel.class);

    for(File iterateFiles:allSubFiles)                    
    {
    final Message<File> messageFile = MessageBuilder.withPayload(iterateFiles).build();
        pC.send(messageFile);

        Thread.sleep(2000);
    }
}
