read file from SFTP and dump to local folder using mulesoft

问题

Can someone provide me an mulesoft xml where the flow is reading files from SFTP location and dumping it to the local directory.

I have written following code but it does not work: subflow :

    <sub-flow name="loadFtpFile">
    <logger message="Load FTP File: #[flowVars.fileName]" level="INFO" doc:name="Load FTP File"/>
    <logger message="#[payload]" level="DEBUG" doc:name="Log Payload"/>
</sub-flow>

And the flow is :

<flow name="readFTP">
     <logger message="Read FTP file" level="INFO" doc:name="Read FTP file"/>
    <set-variable variableName="sftpEndpoint" value="sftp://{someUser}:{password}@{host}:22/incoming/test" doc:name="Set SFTP Endpoint"/>
    <set-variable variableName="fileName" value="debug.log" doc:name="Set File Name"/>
    <flow-ref name="loadFtpFile" doc:name="loadFtpFile"/>
   <file:outbound-endpoint path="C:\Users\Vikas\home\product" responseTimeout="10000" doc:name="Templocation" />

here is a example from the official documentation.

configuation:

<mule xmlns="http://www.mulesoft.org/schema/mule/core"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xmlns:sftp="http://www.mulesoft.org/schema/mule/sftp"
      xmlns:file="http://www.mulesoft.org/schema/mule/file"
      xmlns:spring="http://www.springframework.org/schema/beans"
      xsi:schemaLocation="
          http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-current.xsd
          http://www.mulesoft.org/schema/mule/sftp http://www.mulesoft.org/schema/mule/sftp/current/mule-sftp.xsd
          http://www.mulesoft.org/schema/mule/file http://www.mulesoft.org/schema/mule/file/current/mule-file.xsd
          http://www.mulesoft.org/schema/mule/core http://www.mulesoft.org/schema/mule/core/current/mule.xsd">

    <!-- This placeholder bean lets you import the properties from the sftp.properties file. -->
    <spring:bean id="property-placeholder" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <spring:property name="location" value="classpath:sftp.properties"/>
    </spring:bean>

    <flow name="sftp2file">
        <sftp:inbound-endpoint host="${sftp.host}" port="${sftp.port}" path="/home/test/sftp-files" user="${sftp.user}" password="${sftp.password}"> 
                    <file:filename-wildcard-filter pattern="*.txt,*.xml"/> 
                </sftp:inbound-endpoint>
        <file:outbound-endpoint path="/tmp/incoming" outputPattern="#[message.inboundProperties.originalFilename]"/> 
    </flow>
</mule>

and here the references properties file:

sftp.user=memyselfandi
sftp.host=localhost
sftp.port=8081
sftp.password=icannottellyou

try it out and feel free to ask more precise queation.
