Spring integration recipient-list-router issue

Question

I am using a recipient-list-router in my application to send message to different JMS outbound adapters as shown here:

queue -> recipient-list-router  -> queue1 -> JMS outbound adapter 1
                                -> queue2 -> JMS outbound adapter 2

I am facing two issues:

selector-expression runs initially only, not for each message forwarded
if any JMS broker is down then message is not getting sent to another JMS broker.

Following is the XML configuration:

<i:recipient-list-router input-channel="result-pack-output-channel" >
           <i:recipient channel="result-pack-output-channel-1" 
                          selector-expression="#{utils.isHourInInterval('LN')}"/>
            <i:recipient channel="result-pack-output-channel-2" 
                          selector-expression="#{utils.isHourInInterval('NY')}"/>
            <i:recipient channel="result-pack-output-channel-3" 
                        selector-expression="#{utils.isHourInInterval('HK')}" />
            <i:recipient channel="result-pack-output-channel-4" 
                        selector-expression="#{utils.isHourInInterval('ME')}"/> 
 </i:recipient-list-router>

Please show us some java code or the XML configuration of your implementation. Otherwise it´s hard to help you. Also, are you seeing any exceptions? — Tobias, Jul 12 '18 at 07:20

#{...} expressions are evaluated once, during context initialization. Here, you need runtime expressions. In runtime expressions you reference other beans with @ - so...

selector-expression="@utils.isHourInInterval('LN')"

EDIT

I missed your second question - use ignore-send-failures="true">.

Please also mention `AbstractMessageRouter.ignoreSendFailures`. (I've spent too much time in gitter so lost my chance to answer ;-)) – Artem Bilan Jul 12 '18 at 13:08
Thanks @Gary Russell. I did the change but not sure whether expression is working. tried to put log line in bean but not printing. Will update after checking in detail. – Keyur Mahajan Jul 13 '18 at 11:05
@ArtemBilan Thanks for the efforts :) – Keyur Mahajan Jul 13 '18 at 11:05
