Switch ConnectionFactory during runtime

I want to switch the connection to another message broker during runtime.

<bean id="qpidConnectionFactory" class="org.apache.qpid.client.AMQConnectionFactory">
    <constructor-arg name="url" ref="connectionURL" />
</bean>

<bean id="connectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">
    <property name="targetConnectionFactory" ref="qpidConnectionFactory" />
    <property name="sessionCacheSize" value="10" />
</bean>

How can I do this? Maybe with scopes? And what is about services, transaction managers or message listener which using this factory?

<bean id="transactionManager" class="org.springframework.jms.connection.JmsTransactionManager">
    <property name="connectionFactory" ref="connectionFactory" />
</bean>
