    </bean>
    <bean id="myFilter" class="com.ali.util.FtpFilter"/>
    <bean id="onceFilter" class="com.ali.util.OnceFilter"/>
    <int-ftp:inbound-channel-adapter id="ftpInbound1"
                                     channel="inboundFileChannel"
                                     **session-factory="ftpClientFactory"**
                                     charset="UTF-8"
                                     auto-create-local-directory="true"
                                     delete-remote-files="true"
                                     remote-directory="/directoryA"
                                     remote-file-separator="/"
                                     temporary-file-suffix=".writing"
                                     local-filter="myFilter"
                                     filter="onceFilter"
                                     local-directory="file:output">
        **<int:poller fixed-rate="5000"/>**
</int-ftp:inbound-channel-adapter>
    <int-ftp:inbound-channel-adapter id="ftpInbound2"
                                     channel="inboundFileChannel"
                                     **session-factory="ftpClientFactory"**
                                     charset="UTF-8"
                                     auto-create-local-directory="true"
                                     delete-remote-files="true"
                                     remote-directory="/directoryB"
                                     remote-file-separator="/"
                                     temporary-file-suffix=".writing"
                                     local-filter="myFilter"
                                     filter="onceFilter"
                                     local-directory="file:output">
        **<int:poller fixed-rate="5000"/>**
</int-ftp:inbound-channel-adapter>

Is there another way?
