Question

我正在开发一个使用Spring JMS（v3.1.0）来使用来自主题（IBM WebSphere MQ v7）的一些消息的应用程序，并且MQ上的监视显示每次调用我们刷新/重新调用的监听器注册持久订阅。这导致MQ上出现意外的过载。值得一提的是，该应用程序正在IBM WepSphere v7上运行。

这是我们的配置：

<bean id="myMessageListenerContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
    <property name="destinationResolver" ref="jmsDestResolver"/>
    <property name="destination" ref="myTopic"/>
    <property name="connectionFactory" ref="myTopicConnectionFactory"/>
    <property name="messageListener" ref="myMessageListener" />
    <property name="pubSubDomain" value="true" />
    <property name="subscriptionDurable" value="true"/>
    <property name="durableSubscriptionName" value="${durableSubscriptionName}"/>
    <property name="sessionTransacted" value="true"/>
    <property name="transactionManager" ref="transactionManager" />
    <property name="taskExecutor" ref="taskExecutor" />

    <!-- Only CACHE_CONSUMER will lead to a fixed registration:
    http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/jms/listener/DefaultMessageListenerContainer.html#isRegisteredWithDestination%28%29
    -->
    <property name="cacheLevelName" value="CACHE_CONSUMER" />

    <!-- clientId already specified on the Topic Connection Factory -->
</bean>

<!-- Lookup the topic -->
<jee:jndi-lookup id="myTopic" jndi-name="${myTopic.jndiName}" />

<!-- Lookup the topic connection factory -->
<jee:jndi-lookup id="myTopicConnectionFactory" jndi-name="${myTopicConnectionFactory.jndiName}" />

<!-- Implements javax.jms.MessageListener -->
<bean id="myMessageListener" class="com.sample.jms.MyMessageListener" />

<!-- Get WebSphere work manager --> 
<bean id="taskExecutor" class="org.springframework.scheduling.commonj.WorkManagerTaskExecutor">
   <property name="workManagerName" value="${taskManager.jndiName}" />
</bean>

<!-- 
    Lookup WebSpere transaction manager. More info see: 
    http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/transaction.html#transaction-application-server-integration-websphere 
 -->
<bean id="transactionManager" class="org.springframework.transaction.jta.WebSphereUowTransactionManager"/>

修改：这些是我们正在使用的属性：

durableSubscriptionName=myMessageListenerContainer
myTopic.jndiName=jms/myTopic
myTopicConnectionFactory.jndiName=jms/myTopicConnectionFactory
taskManager.jndiName=wm/default

任何想法如何解决？谢谢！安德烈

在我自己的Websphere + Spring研究中，我遇到了这个问题。也许它会对你有所帮助：
