我在AMQ 5.12.0上有一个2代理群集，我正在通过Tomcat 8 Web应用程序发送消息。我有以下Camel（2.15.2）/ Spring（4.2.1）配置。我正在使用它来配置AMQ PooledConnectionFactory。
<camel:camelContext id="camel-client">
<camel:template id="camelTemplate"/>
</camel:camelContext>
<bean id="jmsConnectionFactory"
class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL"
value="failover:(tcp://dev2.wtgroupllc.com:61626?keepAlive=true&daemon=true&connectionTimeout=3000,tcp://dev3.wtgroupllc.com:61626?keepAlive=true&daemon=true&connectionTimeout=3000)?timeout=1000" />
</bean>
<bean id="pooledConnectionFactory"
class="org.apache.activemq.pool.PooledConnectionFactory" init-method="start" destroy-method="stop">
<property name="maxConnections" value="3" />
<property name="connectionFactory" ref="jmsConnectionFactory" />
</bean>
<bean id="jmsConfig"
class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="pooledConnectionFactory"/>
<property name="deliveryPersistent" value="true" />
<property name="concurrentConsumers" value="0"/>
</bean>
<bean id="activemq"
class="org.apache.activemq.camel.component.ActiveMQComponent">
<property name="configuration" ref="jmsConfig"/>
</bean>
当web应用程序启动时，我从beanFactory中获取ProducerTemplate并使用它向“primer”队列发送消息以启动maxConnection连接。随后我使用ProducerTemplate（“camelTemplate”）发送真实消息。只要只有1个经纪人在运行，camelTemplate就可以利用游泳池中的连接......
