我们正在创建一个 Mule 应用程序,它将在 Kubernetes 上的容器中运行,并将位于将连接到 JMS 2.0 Red Hat AMQ 7(基于 ActiveMQ Artemis)的副本集中。
pom.xml 已配置为获取 jms 客户端:
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>artemis-jms-client-all</artifactId>
<version>2.10.1</version>
</dependency>
JMS 配置配置为:
<jms:config name="JMS_Config" doc:name="JMS Config" doc:id="8621b07d-b203-463e-bbbe-76eb03741a61" >
<jms:generic-connection specification="JMS_2_0" username="${mq.user}" password="${mq.password}" clientId="${mq.client.id}">
<reconnection >
<reconnect-forever frequency="${mq.reconnection.frequency}" />
</reconnection>
<jms:connection-factory >
<jms:jndi-connection-factory connectionFactoryJndiName="ConnectionFactory" >
<jms:name-resolver-builder jndiInitialContextFactory="org.apache.activemq.artemis.jndi.ActiveMQInitialContextFactory" jndiProviderUrl="${mq.brokerurl}"/>
</jms:jndi-connection-factory>
</jms:connection-factory>
</jms:generic-connection>
<jms:consumer-config>
<jms:consumer-type >
<jms:topic-consumer shared="true" durable="true"/>
</jms:consumer-type>
</jms:consumer-config>
<jms:producer-config persistentDelivery="true"/>
</jms:config>
然后在 JMS 监听组件中:
<jms:listener doc:name="EMS JMS Listener" doc:id="318b4f08-daf6-41f4-944b-3ec1420d5c12" config-ref="JMS_Config" destination="${mq.incoming.queue}" ackMode="AUTO" >
<jms:consumer-type >
<jms:topic-consumer shared="true" subscriptionName="${mq.sub.name}" durable="true"/>
</jms:consumer-type>
<jms:response sendCorrelationId="ALWAYS" />
</jms:listener>
变量设置为:
mq.client.id=client-id-135a9514-d4d5-4f52-b01c-f6ca34a76b40
mq.sub.name=my-sub
mq.incoming.queue=my-queue
这是配置客户端的最佳方式吗?正如我们在部署到 K8s 时在日志中看到有关与 AMQ 服务器的连接的错误:
javax.jms.InvalidClientIDException: client-id-135a9514-d4d5-4f52-b01c-f6ca34a76b40 was already set into another connection
