How to use the RedeliveryPolicy in case of failed messages for outbound->inbound->httpgateway(messages failing here)->EXTERNAL SERVICE - spring

Question

How to use the RedeliveryPolicy in case of failed messages in outbound->inbound->httpoutboundgateway(messages failing here)->external service
the failed messages are not getting retried based on the RedeliveryPolicy mainly because the message is already dequeued before the exception occurs.
<int:channel id="jmsOutChannel" />
<jms:outbound-channel-adapter id="outboundJMSAdaptor" jms-template="jmsTemplate"
channel="jmsOutChannel"
destination-name="#{somebean.queueName}"/>
<int:channel id="jmsInChannel" />
<jms:message-driven-channel-adapter
channel="jmsInChannel" destination-name="#{somebean.queueName}"
connection-factory="jmsConnectionFactory" message-converter="jmsMessageConverter"/>
<int:header-enricher input-channel="jmsInChannel" output-channel="outbound_gateway_channel">
<int:header name="addressId" expression="payload.getId()"/>
<int:header name="Accept-Language" value="en_GB"/>
<int:header name="X-Source-CountryCode" value="GB"/>
<int:header name="X-Source-Operator" value="Enterprise"/>
<int:header name="X-Source-Division" value="CustomerManagement"/>
<int:header name="X-Source-System" value="${sapwebservices.http.header.source.system}"/>
<int:header name="X-Source-Timestamp" expression="new java.text.SimpleDateFormat('yyyy-MM-dd HH:mm:ss').format(new java.util.Date())"/>
<int:header name="Accept" value="application/json"/>
<int:header name="Content-Type" value="application/json;charset=UTF-8"/>
</int:header-enricher>
<bean id="httpRequestFactory" class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory">
<property name="connectTimeout" value="${sapwebservices.http.rest.timeout}"/>
<property name="readTimeout" value="${sapwebservices.http.rest.timeout}"/>
<property name="httpClient" ref="httpClient"/>
</bean>
<int:object-to-json-transformer input-channel="outbound_gateway_channel"

<http:outbound-gateway mapped-request-headers="Accept*, Content-Type, X-*, HTTP_REQUEST_HEADERS"

expected-response-type="java.lang.String"
charset="UTF-8"
request-factory="httpRequestFactory">
<http:uri-variable name="id" expression="headers['addressId']"/>
</http:outbound-gateway>
And for the redelivery policy I have,
<bean id="jmsTemplate" class="org.springframework.jms.core.JmsTemplate">
<property name="messageConverter" ref="jmsMessageConverter" />
<property name="connectionFactory">
<bean class="org.springframework.jms.connection.SingleConnectionFactory">
<property name="targetConnectionFactory">
<ref local="jmsConnectionFactory" />
</property>
</bean>
</property>
</bean>
<bean id="jmsConnectionFactory" class="org.apache.activemq.spring.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://localhost:61616"/>
<property name="userName" value="admin"/>
<property name="password" value="admin"/>
<property name="redeliveryPolicy" ref="redeliveryPolicy"/>
<property name="nonBlockingRedelivery" value="true"/>
</bean>
<bean id="redeliveryPolicy" class="org.apache.activemq.RedeliveryPolicy">
<property name="maximumRedeliveries" value="${sapwebservice.redeliveryPolicy.maximumRedeliveries}"/>
<property name="initialRedeliveryDelay" value="${sapwebservice.redeliveryPolicy.initialRedeliveryDelay}"/>
<property name="backOffMultiplier" value="${sapwebservice.redeliveryPolicy.backOffMultiplier}"/>
<property name="useExponentialBackOff" value="${sapwebservice.redeliveryPolicy.useExponentialBackOff}"/>
<property name="redeliveryDelay" value="${sapwebservice.redeliveryPolicy.redeliveryDelay}"/>
</bean>
<bean id="demoQueue" class="org.apache.activemq.command.ActiveMQQueue">
<constructor-arg value="demo.queue"/>
</bean>
<bean id="jmsMessageConverter" class="sap.converter.JMSMessageConverter"/>
<amq:broker useJmx="true" persistent="false">
<amq:destinationPolicy>
<amq:policyMap>
<amq:defaultEntry>
<amq:policyEntry queue=">">
<amq:deadLetterStrategy>
<amq:individualDeadLetterStrategy queuePrefix="dlq." useQueueForQueueMessages="true"/>
</amq:deadLetterStrategy>
</amq:policyEntry>
</amq:defaultEntry>
</amq:policyMap>
</amq:destinationPolicy>
<amq:transportConnectors>
<amq:transportConnector uri="tcp://localhost:0" />
</amq:transportConnectors>
</amq:broker>
Expected result is to retry based in the RedeliveryPolicy and finally end up in dlq if all the retrials are failed.

Set acknowledge="transacted" on the message-driven channel adapter.
Spring Integration versions 4.2 and later (the current version is 5.1.7) set it to that by default; for earlier versions you have to set it in your configuration so the flow runs in a transaction and the dequeue is rolled back after an exception is thrown.
