Dynamically selecting a RabbitMq queue in Exchange

From producer I have to send message to an RabbitMQ Exchange. this message will contain specific attribute, for example , queue name, based on this attribute, I have to dynamically decide the queue to send this message.[queue to bind from exchange, to send this particular message].

is there any way to intercept the message arriving to a RabbitMQ Exchange, using spring integration, At present , I have the following spring integration config file.

I don't know to how to create a bean to get Exchange Messages and route the message to smsQueue, emailQueue etc., queues.

thanks for you suggestions and replies.

With RabbitMQ (AMQP) you don't send to queues, you send to exchanges with a routing key, and bindings determine which queue(s) get the message.

<rabbit:direct-exchange name="si.test.exchange">
    <rabbit:bindings>
        <rabbit:binding queue="si_test_queue" key="si.test.binding" />
    </rabbit:bindings>
</rabbit:direct-exchange>

<int-amqp:outbound-channel-adapter
    channel="toRabbit" amqp-template="amqpTemplate" exchange-name="si.test.exchange"
    routing-key="si.test.binding" />

Instead of routing-key you can use routing-key-expression with something like headers['foo'] or @someBean.determineRoutingKeyFor(payload).
