不使用消息驱动通道适配器调用Spring Integration错误通道

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，服务激活器可以抛出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"caller"，只记录RuntimeException（在AbstractMessageListenerContainer基类中） .

可能是我必须扩展DefaultMessageListenerContainer以不同的方式处理RuntimeExceptions，但我想知道是否有人可以指出我更优雅的解决方案或告诉我，我的方法是完全错误的 .

--- JMS Logging（我已经缩进以使其更具可读性） . 日志显示从第一次错误"No file type was found for file 9789814316385.txt"到相同错误的下一次的详细信息（此跟踪无限重复，直到系统关闭 . ）确实 redeliveryCounter is always to 0 我不知道为什么会出现这种情况

附加调试器后，我可以看到服务激活器抛出异常的原因没有传播：

问题发生在 org.springframework.integration.dispatcher.UnicastingDispatcher

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;
}

如果成功处理消息，上面显示的doDispatch将循环 Iterator<MessageHandler> handlerIterator = this.getHandlerIterator(message); 返回的每个MessageHander .

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，它将传递给下面显示的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）并且消息只是继续被重新传递 . 有谁知道为什么这个JmsSendingMessageHandler也试图处理为Service Activator指定的消息？
