Using spring-integration 5.0.7 to throttle the bridging of msgs between two JMS queues.
suggest:
<int:bridge input-channel="pollable" output-channel="subscribable">
<int:poller max-messages-per-poll="10" fixed-rate="5000"/>
</int:bridge>
But schema validator complains "no nested poller allowed for subscribable input channel" on bridge elt.
But, if I put the poller on the input-channel-adapter as in:
<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns:int="http://www.springframework.org/schema/integration"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

">
<int:channel id="inChannel" />
<int:channel id="outChannel" />
<int-jms:inbound-channel-adapter id="jmsIn" connection-factory="jmsConnectionFactory" destination-name="_dev.inQueue" channel="inChannel">
<int:poller fixed-delay="5000" max-messages-per-poll="2"/>
</int-jms:inbound-channel-adapter>
<int-jms:outbound-channel-adapter id="jmsOut" connection-factory="jmsConnectionFactory" destination-name="_dev.outQueue" channel="outChannel"/>
<int:bridge input-channel="inChannel" output-channel="outChannel">
</int:bridge>
</beans:beans>
Nothing is ever moved from input to output.
How can I bridge from one JMS queue to another with a rate-limit?
Update:
Turning on logging confirms nothing getting picked up from input channel but otherwise not helpful:
