Re Read file when using int-sftp:inbound-channel-adapter

Question

I have a int-sftp:inbound-channel-adapter which uses SftpPersistentAcceptOnceFileListFilter as part of a composite filter. Reading the documentation/ source code it should accept a file to be read again if the modified datetime has changed, but I cant get it to work, it only reads is the once. Im using redis as the store.

Any ideas what is wrong with the configuration, Im using spring integration 4.3.5

<int-sftp:inbound-channel-adapter id="sftpInboundAdapterCensus"
    channel="sftpInboundCensus"
    session-factory="sftpSessionFactory"
    local-directory="${sftp.localdirectory}/census-local"
    filter="censusCompositeFilter"
    remote-file-separator="/"
    remote-directory="${sftp.directory.census}">
    <int:poller cron="${sftp.cron}" max-messages-per-poll="1" error-channel="pollerErrorChannel"/>
</int-sftp:inbound-channel-adapter>

<bean id="censusCompositeFilter"
class="org.springframework.integration.file.filters.CompositeFileListFilter">
<constructor-arg>
 <list>
     <bean class="org.springframework.integration.sftp.filters.SftpSimplePatternFileListFilter">
         <constructor-arg value="*.xml" />
     </bean>
     <bean id="SftpPersistentAcceptOnceFileListFilter" class="org.springframework.integration.sftp.filters.SftpPersistentAcceptOnceFileListFilter">
         <constructor-arg ref="metadataStore" />
         <constructor-arg value="censusSampleLock_" />
     </bean>
 </list>
</constructor-arg>
</bean>

The SftpPersistentAcceptOnceFileListFilter only controls what we fetch from the server. You also need a FileSystemPersistentAcceptOnceFileListFilter in the local-filter (which determines which files that have been fetched end up being emitted as messages). The local filter is an AcceptOnceFileListFilter by default.

Thanks again Gary, that worked. Ive reread the documentation and actually it does say exactly that, I must have mis read it. http://docs.spring.io/autorepo/docs/spring-integration/4.3.7.RELEASE/reference/html/sftp.html – sdiaz1000 Apr 28 '17 at 07:08
