I have a JMS outbound gateway which i use to send messages to multiple queues in a queue manager. The destination is determined on the fly using the destinationExpression method:

@Bean
public IntegrationFlow sendTo101() {
    return flow -> flow
            .handle(Jms
                    .outboundAdapter(context.getBean("connection101", ConnectionFactory.class))
                    .destinationExpression("headers.destinationName")
                    .configureJmsTemplate(spec -> spec
                            .explicitQosEnabled(true)
                            .get().setDeliveryDelay(180000)
                    )
                    .get(),
                    endpointSpec -> endpointSpec.advice(context.getBean(RequestHandlerRetryAdvice.class))
            );

}

Now there's a need to set a delivery delay to a certain subset of messages that come in. Is there any way to use the contents of the message to determine if i should add a delay or not?

I could have a filter further up which checks for this property and redirects the flow to another outbound gateway, but that would be quite a bit of redundant code so i wanted to make sure that there wasn't a better way.

Also, different messages require different delays. Is it possible to set a different delay per message? I do realize that the delay property is on the Message Producer and not something you set on the message according to the JMS spec, but i'm fine with making a new JMS producer per message even though it hinders performance.

Thanks for the help!
