AMQP-206 Support Rabbit HA

[garyrussell]

• Configure a list of addresses in ConnectionFactory
• Allow arguments (e.g. HA) for temporary reply queue creation

AMQP-206 Add queue-arguments Attribute

now supports either element
or a queue-arguments attribute which is a reference to
a bean.

is promoted to a top-level bean,
allowing for re-use, such as...

<rabbit:queue-arguments id="haArgs">
<entry key="x-ha-policy" value="all" />
</rabbit:queue-arguments>

<rabbit:queue name="si.test.queue" queue-arguments="haArgs" />

AMQP-206 Fix Parser Tests

AMQP-206 ReConnect To Mirrored Queue

If a consumer is connected to a mirror (slave), and the
master dies, the queue is moved. The consumer is given a
cancel notification, indicating we need to reconnect.

However, the move might not be complete, so we retry the
queue declaration a number of times before failing.

AMQP-206 Polishing

Cleanup retry counter name; trap exception on cancel of
temporary reply queue.

AMQP-206 Add reply-queue to RabbitTemplate

Allow specification of an explicit queue for replies. Adds
a correlation header to sendAndReceive messages (spring_reply_correlation)
which is used to correlate replies on the reply queue.

The queue is supplied to the template via the reply-queue
attribute; the template must be added as a to a
for the same queue. For example...

<rabbit:template id="amqpTemplate" connection-factory="connectionFactory" reply-queue="si.test.replies" />

<rabbit:listener-container id="replyContainer" connection-factory="connectionFactory" task-executor="reply-exec">
    <rabbit:listener ref="amqpTemplate" queues="si.test.replies"/>
</rabbit:listener-container>

<rabbit:queue name="si.test.replies" queue-arguments="haArgs" />

AMQP-206 Stack Reply Correlation

Stacks (pushes/pops) correlation when using a fixed queue for
replies in sendAndReceive methods.

Now supports

templatsendAndReceive()->listener->templateSendAndReceive()->
listener->templateSendAndReceive->...

and the replies get correlated in each template appropriately.

AMQP-206 Polishing

Add exclusive test for addresses attribute; add parser test.

AMQP-206 Polishing

Improve configuration of reply-queue listener on rabbit template.
Previously a disjoint listener was required. Now the listener
is a child element of the template itself.

<rabbit:template id="withReplyQ" connection-factory="connectionFactory" reply-queue="reply.queue">
    <rabbit:reply-listener />
</rabbit:template>

The reply-listener is a full-blown listener container, but uses the
template's connection factory and so that attribute, as well as the
message-converter is disallowed at run-time.

AMQP-206 Polishing

Remove disallowed attributes from child element
in schema.
