Polled Inbound Channel Adapter

Overview

Version 5.0.1 introduced a polled channel adapter, letting you fetch individual messages on demand — for example, with a MessageSourcePollingTemplate or a poller. See Deferred Acknowledgment Pollable Message Source for more information.

It does not currently support XML configuration.

The following example shows how to configure an AmqpMessageSource:

Java DSL
Java

@Bean
public IntegrationFlow flow() {
    return IntegrationFlow.from(Amqp.inboundPolledAdapter(connectionFactory(), DSL_QUEUE),
                    e -> e.poller(Pollers.fixedDelay(1_000)).autoStartup(false))
            .handle(p -> {
                ...
            })
            .get();
}

@Bean
public AmqpMessageSource source(ConnectionFactory connectionFactory) {
    return new AmqpMessageSource(connectionFactory, "someQueue");
}

See the Javadoc for configuration properties.

XML

This adapter currently does not have XML configuration support.

Batched Messages

See Batched Messages.

For the polled adapter, there is no listener container, batched messages are always debatched (if the BatchingStrategy supports doing so).
