使用消息驱动的通道适配器

时间：2015-07-23 19:07:46

标签： error-handling spring-integration spring-jms

注意：由于我正在处理的项目的依赖性要求，我使用的是Spring Integration 3.0.5.RELEASE。

我已经使用重新传递策略配置了连接工厂（我们使用的是Active MQ 5.7）

<amq:connectionFactory id="cms.jmsConnectionFactory"
    brokerURL="${cms.jms.brokerURL}" p:redeliveryPolicy-ref="cms.jms.redeliveryPolicy"
    p:prefetchPolicy-ref="cms.jms.prefetchPolicy" p:userName="${cms.jms.userName}" p:password="${cms.jms.password}"/>


<amq:redeliveryPolicy id="cms.jms.redeliveryPolicy"
    p:backOffMultiplier="5"
    p:initialRedeliveryDelay="1000"
    p:maximumRedeliveries="6"
    p:redeliveryDelay="1000"
    p:useExponentialBackOff="false"
    p:useCollisionAvoidance="false" />

我有一个服务激活器，它通过消息驱动通道适配器上的消息激活

<int-jms:message-driven-channel-adapter channel="cms.jms.archiveNodeChannel"
    connection-factory="cms.jms.cachedConnectionFactory" destination="cms.jms.archiveNodeDestination" transaction-manager="cms.jms.txManager"
    acknowledge="transacted" concurrent-consumers="1" max-concurrent-consumers="1" cache-level="3"/>

<int:service-activator ref="cms.int.nodeArchiver" method="archiveNode" input-channel="cms.jms.archiveNodeChannel"/>

在某些情况下，服务激活器可能会抛出RuntimeException。我想要的行为是根据重新传递策略的maximumRedeliveries属性重新传递消息6次，然后在Spring Integration层调用错误处理程序但是抛出RuntimeException时实际发生了什么是消息重新传递，直到我杀死应用程序。我尝试将错误通道添加到消息驱动通道适配器，但从未激活过。

This post略显陈旧，但建议在JMS消息驱动的场景中。 DefaultMessageListenerContainer是“调用者”，只记录RuntimeException（在AbstractMessageListenerContainer基类中）。

我可能需要扩展DefaultMessageListenerContainer以不同方式处理RuntimeExceptions，但我想知道是否有人能指出我更优雅的解决方案或者告诉我，我的方法完全错误。

--- JMS Logging（我已经缩进以使其更具可读性）。日志显示从第一个错误“找不到文件9789814316385.txt的文件类型”到下一次出现相同错误时的详细信息（此跟踪在无限期重复，直到系统关闭。）的确如此 redeliveryCounter总是为0 我不知道为什么会这样呢

附加了调试器后，我可以看到服务激活器抛出异常的原因没有传播：

问题出现在org.springframework.integration.dispatcher.UnicastingDispatcher

中 
private boolean doDispatch(Message<?> message) {
    boolean success = false;
    Iterator<MessageHandler> handlerIterator = this.getHandlerIterator(message);
    if (!handlerIterator.hasNext()) {
        throw new MessageDispatchingException(message, "Dispatcher has no subscribers");
    }
    List<RuntimeException> exceptions = new ArrayList<RuntimeException>();
    while (success == false && handlerIterator.hasNext()) {
        MessageHandler handler = handlerIterator.next();
        try {
            handler.handleMessage(message);
            success = true; // we have a winner.
        }
        catch (Exception e) {
            RuntimeException runtimeException = (e instanceof RuntimeException)
                    ? (RuntimeException) e
                    : new MessageDeliveryException(message,
                            "Dispatcher failed to deliver Message.", e);
            if (e instanceof MessagingException &&
                    ((MessagingException) e).getFailedMessage() == null) {
                ((MessagingException) e).setFailedMessage(message);
            }
            exceptions.add(runtimeException);
            this.handleExceptions(exceptions, message, !handlerIterator.hasNext());
        }
    }
    return success;
}

上面显示的doDispatch循环遍历Iterator<MessageHandler> handlerIterator = this.getHandlerIterator(message);返回的每个MessageHander，如果成功处理该消息，则会中断。

handlerIterator包含2个MessageHandlers，第一个是我的Service Activator（抛出RuntimeException），第二个是org.springframework.integration.jms.JmsSendingMessageHandler（我不知道为什么会这里）

当Service Activator抛出异常时，它会传递给下面显示的handleExceptions方法：

/**
 * Handles Exceptions that occur while dispatching. If this dispatcher has
 * failover enabled, it will only throw an Exception when the handler list
 * is exhausted. The 'isLast' flag will be <em>true</em> if the
 * Exception occurred during the final iteration of the MessageHandlers.
 * If failover is disabled for this dispatcher, it will re-throw any
 * Exception immediately.
 */
private void handleExceptions(List<RuntimeException> allExceptions, Message<?> message, boolean isLast) {
    if (isLast || !this.failover) {
        if (allExceptions != null && allExceptions.size() == 1) {
            throw allExceptions.get(0);
        }
        throw new AggregateMessageDeliveryException(message,
                "All attempts to deliver Message to MessageHandlers failed.", allExceptions);
    }
}

由于Service Activator不是最后一个处理程序（isLast = false），因此不会抛出异常。第二个JmsSendingMessageHandler处理消息（虽然我不知道为什么）并且消息只是不断被重新传递。有谁知道为什么这个JmsSendingMessageHandler也试图处理为Service Activator指定的消息？

答案 0 :(得分：0)

<publish-subscribe-channel>适合你！而且你真的可以添加所有这些组件作为订阅它们将在order中调用它们在配置中的声明方式或根据其预先配置的order属性。
