在从 JMS 队列消费消息时，我希望确定消费过程是成功还是失败，如果失败，我希望 activemq 在 1 分钟后再次重新传递消息。稍后根据交付计数，我可能会将其发送到 DLQ。

我找到了使用 java 代码实现相同的示例，例如具有不同确认模式的会话或使会话进行事务处理，但无法获得如何使用蓝图文件实现相同的目标。

     <reference id="testIdempotencyStore"
           interface="javax.sql.DataSource"
           filter="(osgi.jndi.service.name=TestContext)">
</reference>

<bean id="simulatorMessages" class="org.apache.camel.processor.idempotent.jdbc.JdbcMessageIdRepository">
    <argument ref="testIdempotencyStore" />
    <argument value="jmsTest" />
</bean>

<reference id="txMgr" interface="javax.transaction.TransactionManager" />

<bean id="xaConnectionFactory" class="org.apache.activemq.ActiveMQXAConnectionFactory">
    <property name="brokerURL" value="${activemq.url}" />
    <property name="watchTopicAdvisories" value="false" />
    <property name="userName" value="${activemq.user}" />
    <property name="password" value="${activemq.password}" />
    <property name="redeliveryPolicy" >
        <bean class="org.apache.activemq.RedeliveryPolicy" >
            <property name="maximumRedeliveries" value="0" />
        </bean>
    </property>
</bean>

<bean id="jcaConnectionFactory" class="org.apache.activemq.jms.pool.JcaPooledConnectionFactory"
      init-method="start" destroy-method="stop">
    <property name="transactionManager" ref="txMgr"/>
    <property name="maxConnections" value="10" />
    <property name="name" value="amq" />
    <property name="connectionFactory" ref="xaConnectionFactory"/>
</bean>

<bean id="jmsTxConf" class="org.apache.activemq.camel.component.ActiveMQConfiguration">
    <property name="connectionFactory" ref="jcaConnectionFactory" />
    <property name="requestTimeout" value="10000" />
    <property name="transactionTimeout" value="30" />
    <property name="cacheLevelName" value="CACHE_NONE" />
</bean>

<bean id="activemq" class="org.apache.activemq.camel.component.ActiveMQComponent" >
    <property name="configuration" ref="jmsTxConf" />
</bean>

<camelContext id="TestContext-jms-dispatcher" trace="false" xmlns="http://camel.apache.org/schema/blueprint" >
    <route id="externalNotificationsDispatchRoute" >
        <from uri="activemq:queue:{{vqueue.name}}" />
        <idempotentConsumer messageIdRepositoryRef="simulatorMessages">
            <header>customId</header>
            <to uri="vm:notificationConsumer" />
        </idempotentConsumer>
    </route>
</camelContext>

如果您还没有这样做，请通读本章以了解有关 JMS XA 事务如何在 JBoss Fuse 中工作的更多信息。

你错过了春天PlatformTransactionManager和其他一些东西。这是一个应该工作的配置示例：

<!-- Service reference to Spring’s PlatformTransactionManager -->
<reference id=”osgiPlatformTransactionManager”
    interface=”org.springframework.transaction.PlatformTransactionManager”&gt;

<!-- Service reference to JTA TransactionManager -->
<reference id=”osgiJtaTransactionManager”
    interface=”javax.transaction.TransactionManager”&gt;

<!-- JMS TX endpoint -->
<bean id=”activemq” class=”org.apache.activemq.camel.component.ActiveMQComponent”&gt;
    <property name=”configuration” ref=”jmsTxConfig”&gt;
</bean>

<bean id=”jmsTxConfig” class=”org.apache.camel.component.jms.JmsConfiguration”&gt;
    <property name=”connectionFactory” ref=”jmsXaPoolConnectionFactory” />
    <property name=”transactionManager” ref=”osgiPlatformTransactionManager” />
    <!-- transacted must be set to “false” for XA transactions -->
    <!-- as it is only meant to be used with local transactions -->
    <property name=”transacted” value=”false” />
</bean>

<!-- The connection factory wrapper to enable auto-enlisting -->
<bean id=”jmsXaPoolConnectionFactory”
    class=”org.apache.activemq.pool.JcaPooledConnectionFactory”&gt;
    <property name=”name” value=”MyXaResource” />
    <property name=”maxConnections” value=”1” />
    <property name=”connectionFactory” ref=”jmsXaConnectionFactory” />
    <property name=”transactionManager” ref=”osgiJtaTransactionManager” />
</bean>

<bean id=”jmsXaConnectionFactory”
    class=”org.apache.activemq.ActiveMQXAConnectionFactory”&gt;
    <property name=”brokerURL” value=”${activemq.url}” />
    <property name=”userName” value=”${activemq.user}” />
    <property name=”password” value=”${activemq.password}” />
    <property name="watchTopicAdvisories" value="false" />
    <property name="redeliveryPolicy" >
    <bean class="org.apache.activemq.RedeliveryPolicy" >
        <property name="maximumRedeliveries" value="0" />
    </bean>
</property>
</bean>

<!-- ActiveMQ XA Resource Manager -->
<bean id=”resourceManager” class=”org.apache.activemq.pool.ActiveMQResourceManager”
    init-method=”recoverResource”&gt;
    <property name=”transactionManager” ref=”osgiJtaTransactionManager” />
    <property name=”connectionFactory” ref=”jmsXaConnectionFactory” />
    <property name=”resourceName” value=”activemq.default” />
</bean>

<!-- Transaction Policy to be referenced by the transacted-component in a route -->
<bean id=”txPolicy” class=”org.apache.camel.spring.spi.SpringTransactionPolicy”&gt;
    <property name=”transactionManager” ref=”osgiPlatformTransactionManager” />
    <!-- PROPAGATION_REQUIRED is the default value if a behavior is not set -->
    <property name=”propagationBehaviorName” value=”PROPAGATION_REQUIRED” />
</bean>
