Support for ReturnListener on RabbitTemplate???

[nicolas.loriente]

I don't see a way to register a ReturnListener (used for mandatory and immediate undeliverable messages) on RabbitTemplate? It seems basic functionality... Plans to add it on future realease?

Thanks,

It was added in the 1.1.0.RELEASE; current version is 1.1.1.RELEASE.

See

	public void setReturnCallback(ReturnCallback returnCallback)

.

The RabbitTemplate.ReturnCallback looks like this...

	public static interface ReturnCallback {

		void returnedMessage(Message message, int replyCode, String replyText,
				String exchange, String routingKey);
	}

Requires:

1. A ConnectionFactory with

publisher-returns="true"

2. Only one ReturnCallback can be registered with each RabbitTemplate
3. Also need to setMandatory(true) / setImmediate(true) on the template.

We need to add this information to the reference guide I've opened a JIRA issue for that... https://jira.springsource.org/browse/AMQP-240

Hi Gary,

Thanks for the quick and detailed response. I see it on the APIs but there seems to be no schema support. Is this the case at this point?

Thanks,

This is on the template element in the 1.1 schema...

<xsd:attribute name="return-callback" type="xsd:string" use="optional">
	<xsd:annotation>
		<xsd:documentation><![CDATA[
A reference to an implementation of RabbitTemplate.ReturnCallback - invoked if
a return is received for a message published with mandatory or immediate set
that couldn't be delivered according to the semantics of those options.
		]]></xsd:documentation>
		<xsd:appinfo>
			<tool:annotation kind="ref">
				<tool:expected-type type="org.springframework.amqp.core.RabbitTemplate.ReturnCallback" />
			</tool:annotation>
		</xsd:appinfo>
	</xsd:annotation>
</xsd:attribute>
<xsd:attribute name="confirm-callback" type="xsd:string" use="optional">
	<xsd:annotation>
		<xsd:documentation><![CDATA[
A reference to an implementation of RabbitTemplate.ConfirmCallback - invoked if
a confirm (ack or nack) return is received for a published message.

Hi Gary,

Yes, you are right... I see it on the distribution. I had only checked to see if it was posted here http://www.springframework.org/schema/rabbit.

Thanks,

Nick.

Thanks; I see the 1.1 schema is missing from the site; sorry about that; I will fix it now.
