Question

有效负载不会路由到全局出站队列jms：// orders-queue。它在流程中被注释掉了。但是，当我使用flow-ref = process-orders时，消息将被分派到process-orders流。为什么通过vm调度不起作用？

    <vm:endpoint name="orders-queue" path="email.orders.in" exchange-       pattern="one-way" doc:name="VM"/>


         <vm:endpoint name="events-queue" path="email.orders.in" exchange-pattern="one-way" doc:name="VM"/>

<flow name="order-flow" processingStrategy="synchronous">
        <vm:inbound-endpoint exchange-pattern="one-way" path="order-process.queue1" doc:name="VM" />
    <!--<vm:outbound-endpoint exchange-pattern="one-way" ref="email.orders.in" doc:name="VM"/>-->
    <flow-ref name="process-orders" />
              <catch-exception-strategy doc:name="Processing Exception">
        <logger
            message="Error  during  flow - #[message] :: ExceptionSummary::= #[exception.summaryMessage]"
            level="ERROR" doc:name="Logger" />
    </catch-exception-strategy>
</flow>


<flow name="process-orders" processingStrategy="synchronous">
    <vm:inbound-endpoint exchange-pattern="one-way" ref="email.orders.in" doc:name="VM"/>
    <custom-transformer class="com.sw.CustomTransformer" doc:name="Java"/>

    <logger message="Received Order : #[payload]" level="DEBUG" doc:name="Logger"/>
        <foreach collection="#[message.payload]" doc:name="For Each"
            rootMessageVariableName="Original">
            <flow-ref name="process.order" doc:name="Flow Reference"/>
        </foreach>
</flow>

<sub-flow name="process.order">
    <processor-chain doc:name="Processor Chain" name="Event_Process_Queueing">
        <jms:outbound-endpoint queue="per.order.queue" 
            connector-ref="jmsConnector" doc:name="JMS - Send to Processing Queue"/>
    <test:component/>       
    </processor-chain>
   </sub-flow>

您的配置中几乎没有错误： - 第一个 process.order 是不是流，而是子流，您无法在子流中保留入站VM端点来调用它。
因此，为了将有效负载路由到您配置 email.orders.in 的全局VM队列，您可以按照以下配置示例进行操作： -

    <vm:endpoint name="orders-queue" path="email.orders.in" exchange-pattern="one-way" doc:name="VM"/>
    <http:listener-config name="HTTP_Listener_Configuration2" host="localhost" port="8081"  doc:name="HTTP Listener Configuration" />

    <flow name="Flow">
        <http:listener config-ref="HTTP_Listener_Configuration2" path="/test" doc:name="HTTP"/>
        <set-payload value="Test payload" doc:name="Set Payload"/>
        <vm:outbound-endpoint exchange-pattern="one-way" ref="orders-queue" doc:name="VM"/>
    </flow>

    <flow name="Flow2">
        <vm:inbound-endpoint exchange-pattern="one-way" ref="orders-queue"  doc:name="VM"/>
      <logger message="Received Message in Processing Queue : #[payload]" level="INFO" doc:name="Logger" />
    </flow>

<强>更新： -

根据您在下面的评论，您在使用Global VM连接器引用VM入站和出站端点时遇到了重大错误。
它应该如下： -

 <vm:outbound-endpoint exchange-pattern="one-way" ref="events-queue" doc:name="VM"/>

和

 <vm:inbound-endpoint exchange-pattern="one-way" ref="events-queue" doc:name="VM"/>

您指的是ref="email.orders.in"哪个错误，应该是ref="events-queue"，如上所述，名称为Global VM connector

未调用VM端点
