我正在使用Apache Camel和camel-amqp组件来与ASB队列进行通信。
<bean id="jmsConnectionFactory" class="org.apache.qpid.jms.JmsConnectionFactory">
<property name="remoteURI" value="amqps://${service.bus.uri}?amqp.idleTimeout=120000" />
<property name="username" value="${service.bus.username}" />
<property name="password" value="${service.bus.password}" />
<property name="receiveLocalOnly" value="true" />
</bean>
<bean id="jmsCachingConnectionFactory" class="org.springframework.jms.connection.CachingConnectionFactory">
<property name="targetConnectionFactory" ref="jmsConnectionFactory" />
</bean>
<bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="jmsCachingConnectionFactory"/>
<property name="cacheLevelName" value="CACHE_CONSUMER"/>
</bean>
...
<route>
...
<to uri="amqp:queue:{{service.bus.queue}}?exchangePattern=InOnly"/>
</route>
我的路由第一次运行时，将为 {{service.bus.queue}} 创建 AmqpFixedProducer。如果我设法重新运行路由(10 分钟后(，则出现以下错误：
Caused by: javax.jms.JMSException: The link 'G24:360891:qpid-jms:sender:ID:b60452dd-5a2e-4478-a462-7ca280ecd953:1:2:1:themis-test' is force detached by the broker due to errors occurred in publisher(link252).

似乎应用程序对两个调用使用相同的生产者，因为与 ASB 的连接在 10 分钟后关闭。
我的问题是我该如何管理？
有没有办法检索由 Camel 自动创建的生产者，并且 OnException 部分关闭它并重试？我怎样才能找到制片人？
多谢！
通过将
cacheLevelName修改为CACHE_NONE而不是CACHE_CONSUMER解决了问题。
<bean id="jmsConfig" class="org.apache.camel.component.jms.JmsConfiguration">
<property name="connectionFactory" ref="jmsCachingConnectionFactory"/>
<property name="cacheLevelName" value="CACHE_NONE"/>
</bean>
