Spring integration for sftp

Question

How can I move file from local system to remote FTP using SFTP adapter. I am going through the examples and all are mentioning to copy files from remote FTP to local machine

Here's configuration based on yours that I actually checked to be working, you can use it as a starting point.

<?xml version="1.0" encoding="UTF-8"?>

<bean id="sftpSessionFactory" class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory">
    <property name="host" value="localhost"/>
    <property name="user" value="user01"/>
    <property name="password" value="abc123"/>
    <property name="port" value="990"/>
</bean>

<int:channel id="sftpChannel"/>

<file:inbound-channel-adapter directory="#{T(System).getProperty('java.io.tmpdir')}" id="fileInbound"
                              channel="sftpChannel" filename-pattern="*.xml">
    <int:poller fixed-rate="1000" max-messages-per-poll="100"/>
</file:inbound-channel-adapter>

<int-sftp:outbound-channel-adapter id="sftpOutboundAdapter" session-factory="sftpSessionFactory"
                                   channel="sftpChannel" charset="UTF-8" remote-directory="/"
                                   remote-file-separator="/"/>

</beans>

Problems with your configuration:

1. You use sftpSessionFactory as a channel in inbound-channel-adapter. It should define the message channel to which the payload shall be forwarded to, so in your case it seems like it should be publishToSFTPChannel
2. publish-subscribe-channel used instead of simple point-to-point channel
