Question

我正在尝试配置Apache ServiceMix以实现以下网络拓扑：

enter image description here

我在Service Mix，Camel，ActiveMq等方面很新，我试图解决的主要问题是将消息从DC1.ActiveMqBroker的输出队列路由到DC2.ActiveMqBroker的Input队列。

我确信这应该很容易。有人能指出我的好文章或编写粗略的配置片段（在Spring / Blueprint中，无所谓）？

更新

很抱歉长篇文章，但我没有看到其他方式来解释我的问题。

我的示例配置：

<broker xmlns="http://activemq.apache.org/schema/core" brokerName="dc2" dataDirectory="${karaf.data}/activemq/dc2" useShutdownHook="false">
    <destinationPolicy>
        <policyMap>
            <policyEntries>
                <policyEntry queue="input" producerFlowControl="true" memoryLimit="1mb"/>
                <policyEntry queue="output" producerFlowControl="true" memoryLimit="1mb"/>
            </policyEntries>
        </policyMap>
    </destinationPolicy> 
    <managementContext>
        <managementContext createConnector="false"/>
    </managementContext>
    <persistenceAdapter>
        <kahaDB directory="${karaf.data}/activemq/dc2/kahadb"/>
    </persistenceAdapter>
    <transportConnectors>
        <transportConnector name="openwire" uri="tcp://localhost:61619"/>
    </transportConnectors>
</broker>

<bean id="dc1activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">
    <property name="brokerURL" value="tcp://localhost:61619" />
</bean>

<bean id="dc2activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">
    <property name="brokerURL" value="tcp://localhost:61618" />
</bean>

<camelContext xmlns="http://camel.apache.org/schema/blueprint">
    <route>
        <from uri="dc1activemq:queue:output"/>
        <log message="Took message from dc1 to dc2"/>
        <to uri="dc2activemq:queue:input"/>
    </route>
</camelContext>

我经常遇到以下错误：

我假设你已经掌握了Camel如何在ServiceMix中启动并且有一些（至少）概念验证路线......如果没有，start there。还假设您知道2个消息代理的URL，并且它们已经设置好了。

鉴于此，一种解决方案是注册两个ActiveMQComponents：

<bean id="dc1activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">
   <property name="brokerURL" value="tcp://DC1BrokerLocation:12345" />
</bean>

<bean id="dc2activemq" class="org.apache.activemq.camel.component.ActiveMQComponent">
   <property name="brokerURL" value="tcp://DC2BrokerLocation:12345" />
</bean>

然后在你的骆驼背景中：

<camelContext xmlns="http://camel.apache.org/schema/blueprint">
   <route>
      <from uri="dc1activemq:queue:whateverTheOutQueueIsCalled"/>
      <log message="Took message from dc1 to dc2"/>
      <to uri="dc2activemq:queue:whateverTheInQueueIsCalled"/>
   </route>
   <route>
      <from uri="dc2activemq:queue:whateverTheOutQueueIsCalled"/>
      <log message="Took message from dc2 to dc1"/>
      <to uri="dc1activemq:queue:whateverTheInQueueIsCalled"/>
   </route>
<camelContext>

使用Service Mix路由队列
