SFTP #Poller not triggering polling nothing happens - spring-integration

Question

I am trying to set the spring boot application which will pool the csv . i do not see any activity happning in the spring boot application nor on filezilla SFTP server but if I change the same code to FTP then it works
#Component
#EnableIntegration
public class IntegrationConfiguration {
#Autowired
FTPConfigProperties ftpConfigProperties;
#Autowired
private BeanFactory beanFactory;
#Value("classpath:certificate.crt")
Resource certficateFile;
#Bean
public SessionFactory<ChannelSftp.LsEntry> ftpSessionFactory() {
DefaultSftpSessionFactory factory = new DefaultSftpSessionFactory();
factory.setHost("127.0.0.1");
factory.setPort(990);
factory.setUser("abhinav");
factory.setPassword("nssdw");
factory.setPrivateKey(certficateFile);
factory.setAllowUnknownKeys(true);
return new CachingSessionFactory<ChannelSftp.LsEntry>(factory, 100000);
}
#Bean
public SftpInboundFileSynchronizer ftpInboundFileSynchronizer() {
SftpInboundFileSynchronizer fileSynchronizer = new SftpInboundFileSynchronizer(ftpSessionFactory());
fileSynchronizer.setDeleteRemoteFiles(false);
fileSynchronizer.setRemoteDirectory("/");
fileSynchronizer.setFilter(filter());
fileSynchronizer.setDeleteRemoteFiles(false);
fileSynchronizer.setPreserveTimestamp(true);
fileSynchronizer.setBeanFactory(beanFactory);
return fileSynchronizer;
}
//here the poller is configured
#Bean
#InboundChannelAdapter(channel = "fromSftpChannel", poller = #Poller(fixedDelay = "10000"))
public MessageSource<File> ftpMessageSource() throws Exception {
SftpInboundFileSynchronizingMessageSource source = new SftpInboundFileSynchronizingMessageSource(
ftpInboundFileSynchronizer());
source.setLocalDirectory(new File("ftp-inbound"));
source.setAutoCreateLocalDirectory(true);
source.setMaxFetchSize(1);
source.setBeanFactory(beanFactory);
source.setUseWatchService(true);
return source;
}
public CompositeFileListFilter<ChannelSftp.LsEntry> filter() {
CompositeFileListFilter<ChannelSftp.LsEntry> filter = new CompositeFileListFilter<ChannelSftp.LsEntry>();
filter.addFilter(new SftpSimplePatternFileListFilter("*.csv"));
filter.addFilter(acceptOnceFilter());
filter.addFilter(new LastModifiedLsEntryFileListFilter());
return filter;
}
#Bean
public SftpPersistentAcceptOnceFileListFilter acceptOnceFilter() {
SftpPersistentAcceptOnceFileListFilter filter = new SftpPersistentAcceptOnceFileListFilter(metadataStore(),"ftpPersistentAcceptOnce");
filter.setFlushOnUpdate(true);
return filter;
}
#Bean
public ConcurrentMetadataStore metadataStore() {
PropertiesPersistingMetadataStore propertiesPersistingMetadataStore = new PropertiesPersistingMetadataStore();
propertiesPersistingMetadataStore.setBaseDirectory("./metastore");
propertiesPersistingMetadataStore.setFileName("ftpStream.properties");
return propertiesPersistingMetadataStore;
}
#Bean
#ServiceActivator(inputChannel = "jobChannel", outputChannel = "nullChannel")
protected JobLaunchingMessageHandler launcher(JobLauncher jobLauncher) {
return new JobLaunchingMessageHandler(jobLauncher);
}
}
here the next call where I trigger the spring batch then it goes to service actuator
#Component
public class FileToJobTransformer implements ApplicationContextAware {
private ApplicationContext context;
#Autowired
private Job job;
#Transformer(inputChannel = "fromSftpChannel", outputChannel = "jobChannel")
public JobLaunchRequest transform(File aFile) throws Exception {
String fileName = aFile.getName();
JobParameters jobParameters = new JobParametersBuilder().addString(
"input.file", aFile.getAbsolutePath()).toJobParameters();
JobLaunchRequest request = new JobLaunchRequest(job, jobParameters);
return request;
}
#Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.context = applicationContext;
}
}
the custome code is as follow
public class LastModifiedLsEntryFileListFilter implements FileListFilter<ChannelSftp.LsEntry> {
private static final long DEFAULT_AGE = 60;
private volatile long age = DEFAULT_AGE;
public long getAge() {
return this.age;
}
public void setAge(long age) {
setAge(age, TimeUnit.SECONDS);
}
public void setAge(long age, TimeUnit unit) {
this.age = unit.toSeconds(age);
}
#Override
public List<ChannelSftp.LsEntry> filterFiles(ChannelSftp.LsEntry[] files) {
System.out.println("files = [" + files.length + "]");
List<ChannelSftp.LsEntry> list = new ArrayList<ChannelSftp.LsEntry>();
long now = System.currentTimeMillis() / 1000;
for (ChannelSftp.LsEntry file : files) {
if (file.getAttrs()
.isDir()) {
continue;
}
int lastModifiedTime = file.getAttrs()
.getMTime();
if (lastModifiedTime + this.age <= now) {
list.add(file);
}
}
Collections.reverse(list);
ArrayList<ChannelSftp.LsEntry> oneElementList = new ArrayList<ChannelSftp.LsEntry>(1) ;
oneElementList.add(list.get(0));
return oneElementList;
}
}
