how to polling int:gateway to start int-ftp:outbound-gateway? - spring

Question

firstly thanks for attention
i define outbound-gateway ftp adapter to run ftp command on target server,my goal is run periodically ls,mv,get,... commands on server and run task on batch library job, my code is:
<bean id="ftpClientFactory1" class="org.springframework.integration.ftp.session.DefaultFtpSessionFactory">
<property name="host" value="127.0.0.1"/>
<property name="port" value="21"/>
<property name="username" value="banks_reader"/>
<property name="password" value="123456"/>
<property name="clientMode" value="2"/>
<property name="fileType" value="2"/>
</bean>
<int:gateway id="gw" service-interface="ir.ali.util.ToFtpFlowGateway"
default-request-channel="inbound1"/>
<int:channel id="inbound1"/>
<int-ftp:outbound-gateway id="gateway1"
session-factory="ftpClientFactory1"
request-channel="inbound1"
reply-channel="outbound"
reply-timeout="777"
auto-create-local-directory="false"
auto-startup="true"
filename-pattern="*"
remote-file-separator="/"
command="ls"
command-options="-dirs -R"
expression="payload"
mput-regex=".*"
>
</int-ftp:outbound-gateway>
<int:channel id="outbound">
<int:interceptors>
<int:wire-tap channel="logger"/>
</int:interceptors>
</int:channel>
<int:channel id="outboundJobRequestChannel"/>
<int:logging-channel-adapter id="logger" log-full-message="true" />
<int:transformer input-channel="outbound" output-channel="outboundJobRequestChannel">
<bean class="ir.ali.configuration.FileMessageToJobRequest"/>
</int:transformer>
<int:splitter id="splitter" input-channel="outbound" output-channel="ftpChannel"/>
<int:channel id="ftpChannel">
<int:queue/>
</int:channel>
and in Application Class send message to inbound1 channel and start int-ftp:outbound-gateway the code is:
final ToFtpFlowGateway toFtpFlow = ctx.getBean(ToFtpFlowGateway.class);
try {
List<Boolean> rmResults = toFtpFlow.lsGetAndRmFiles("/");
} catch (Exception e) {
e.printStackTrace();
}
it's worked correctly , the problem is that i needed run periodically ls and mv ,... recursive command on the server,how to run toFtpFlow.lsGetAndRmFiles("/"); periodically to start int-ftp:outbound-gateway ?
