Looping channel to update the header enricher to place file in multiple targets












0














Trying to place a file in multiple directories using single outbound gateway using spring-integration-file.I Know that it's not possible with such a channel adapter to send to several directories at a time.



In order to achieve that, having a loop in front of the file:outbound-gateway to modify message header target directory on each iteration and send all of them to the same channel again and again.



But getting exception as mentioned below.



Any suggestion how to loop it or update the header and execute the adapter again



file : Outbound gateway:



<!-- header enricher -->
<integration:header-enricher input-channel="filesHeaderEnricherChannel" output-channel="filesOut">
<integration:header name="TARGET_COUNT" method="getTargetCount" ref="headerEnricher"/>
<integration:header name="TARGET_DIR" method="getTargetPath" ref="headerEnricher"/>
</integration:header-enricher>

<integration:chain id="filesOutChain" input-channel="filesOut">
<integration:transformer expression="headers.FILE"/>
<file:outbound-adapter id="fileMover"
auto-create-directory="true"
directory-expression="headers.TARGET_DIR"
mode="REPLACE">
<file:request-handler-advice-chain>
<ref bean="retryAdvice" />
</file:request-handler-advice-chain>
</file:outbound-adapter>
</integration:chain>

<!-- decreasing the count on each loop -->
<!-- looping to header enricher channel again as output channel to update the target directory -->
<integration:filter input-channel="filesOut" expression="headers.TARGET_COUNT != 0" output-channel="filesHeaderEnricherChannel"
discard-channel="filesArchiveChannel" throw-exception-on-rejection="true">
<integration:request-handler-advice-chain>
<ref bean="retryAdvice" />
</integration:request-handler-advice-chain>
</<integration:filter>

          You don't need to have a <integration:gateway request-channel="filesOutChainChannel" in the end of your chain. you should just configure a chain to output into the filesOutChainChannel and there in the filter it seems you do right things.



          The problem with the gateway that it waits for reply, but since you loop it into the filesHeaderEnricherChannel back you grow the call stack with with waiting gateways again and again.

          • have tried your solution. am not getting the call stack exception now after replaced the gateway with adapter. But the call doesnot go back to the loop "filesHeaderEnricherChannel". attached edited code above for your reference.

          • Looks like you didn't understand me and did a big mistake in your config. Now you have to round-robin subscribers on the filesOut channel. My point was to have an outpup-channel on the chain, however I see you have changed a gateway to the ` <file:outbound-adapter>, so you are not going to wait for reply. That's fine too. so, consider to make that filesOut` as <publish-subscribe-channel>. Also not sure why do you need a retryAdvice on that filter...
