我有一个使用 Spring MessageListenerContainers 和 ActiveMQ 的应用程序。按照 activemq 的文档，我已将其配置为使用 PooledConnectionFactory。
我的情况如下：
- 来自队列的两个 java-app 消费者（2 个不同的 tomcat）
- 主从 activemq 代理，带有故障转移 url
- PooledConnectionFactory 已配置
- 应用程序上的骆驼
- activemq 5.8.0，带有commons-pool 1.6
一切似乎都正常，但有时消息会重新传递给消费者，这会导致应用程序错误。
根据日志，我怀疑此错误是由 spring 的 PooledConnectionFactory bean 定义中的一些错误配置引起的，该定义甚至关闭了已使用的连接，然后强制回滚当前会话，从而重新传递消息
池的弹簧配置如下：
<bean id="AMQconnFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL">
<value>${activemq_url}?initialReconnectDelay=100&timeout=3000&jms.prefetchPolicy.all=1&jms.redeliveryPolicy.initialRedeliveryDelay=300000
</value>
</property>
</bean>
<bean id="sharedConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory" abstract="true">
<property name="connectionFactory" ref="AMQconnFactory" />
<property name="maxConnections" value="30" />
</bean>
<bean id="MotionJMSConnectionFactory" parent="sharedConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory"
init-method="start" destroy-method="stop" />
<bean id="sharedListenersProps" abstract="true" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<property name="maxConcurrentConsumers" value="1" />
<property name="concurrentConsumers" value="1" />
<property name="connectionFactory" ref="MotionJMSConnectionFactory" />
<property name="sessionTransacted" value="true" />
<property name="transactionTimeout" value="300"/>
</bean>
将我指向该方向的日志如下：

如果需要，我可以提供更多细节。
此致。

另外，我尝试将池大小减少到 1，现在，我更经常地收到以下堆栈（警告）：
