Spring integration ftp/sftp spring集成-localDirectory不能为null
我正在尝试轮询ftp服务器的文件并处理它们。我想在没有xml配置的情况下完成它。我正在使用SpringBoot(1.2.5)和SpringIntegrationFTP(4.1.5) 我为会话工厂创建了一个beanSpring integration ftp/sftp spring集成-localDirectory不能为null,spring-integration,Spring Integration,我正在尝试轮询ftp服务器的文件并处理它们。我想在没有xml配置的情况下完成它。我正在使用SpringBoot(1.2.5)和SpringIntegrationFTP(4.1.5) 我为会话工厂创建了一个bean @Bean public DefaultFtpSessionFactory ftpSessionFactory() { DefaultFtpSessionFactory ftpSessionFactory = new DefaultFtpSessionFactory()
@Bean
public DefaultFtpSessionFactory ftpSessionFactory() {

ftpSessionFactory.setPort(Integer.parseInt(ftpProperties.ftpPort));
ftpSessionFactory.setUsername(ftpProperties.ftpUser);
ftpSessionFactory.setPassword(ftpProperties .ftpPassword);
return ftpSessionFactory;
}
我正在尝试如下配置ftp服务器轮询
@Bean
@InboundChannelAdapter(value = "receiveChannel", poller = @Poller(fixedRate="1000"))
public MessageSource pollFtpForFiles() {
File localDirectory = new File(sftpProperties.localDirectory);
System.err.println("LocalDirectory::"+localDirectory.getAbsolutePath()+"::exists::"+localDirectory.isDirectory());
FtpInboundFileSynchronizer ftpInboundFileSynchronizer = new FtpInboundFileSynchronizer(ftpSessionFactory());
ftpInboundFileSynchronizer.setRemoteDirectory(sftpProperties.remoteDirectory);
ftpInboundFileSynchronizer.synchronizeToLocalDirectory(localDirectory);
return new FtpInboundFileSynchronizingMessageSource(ftpInboundFileSynchronizer);
}
但当我运行应用程序时,我遇到了以下异常。
不知道我做错了什么。谁能帮帮我吗。(我用sftp试过,结果也一样)

谢谢
-Ramesh操作:
ftpInboundFileSynchronizer.synchronizeToLocalDirectory(localDirectory);
这不是你的责任
我相信你的意思就是这个塞特:
FtpInboundFileSynchronizingMessageSource.setLocalDirectory(localDirectory);
换句话说,您的@InboundChannelAdapter
应该如下所示:
@Bean
@InboundChannelAdapter(value = "receiveChannel", poller = @Poller(fixedRate="1000"))
public MessageSource pollFtpForFiles() {
File localDirectory = new File(sftpProperties.localDirectory);
System.err.println("LocalDirectory::"+localDirectory.getAbsolutePath()+"::exists::"+localDirectory.isDirectory());
FtpInboundFileSynchronizer ftpInboundFileSynchronizer = new FtpInboundFileSynchronizer(ftpSessionFactory());
ftpInboundFileSynchronizer.setRemoteDirectory(sftpProperties.remoteDirectory);
FtpInboundFileSynchronizingMessageSource messageSource = new FtpInboundFileSynchronizingMessageSource(ftpInboundFileSynchronizer);
messageSource.setLocalDirectory(localDirectory);
return messageSource;
}
