Spring 集成 AMQP - 消息偶尔未确认，需要超时？

Question

我有一个入站 RabbitMQ 通道适配器，每天成功处理 3000 条消息，但偶尔我会在 RabbitMQ 管理控制台中看到未确认的消息数为 1。这似乎仍然如此。

我确实有一个重试建议链，可以重试 3 次，然后通过死信路由键移动到 DLQ，这对大多数异常都有效。

unacked 在过去几周发生了两次，其中一次我能够进行线程转储并看到 int-http:outbound-gateway 调用卡在等待 http 响应 getStatusCode ()

我在 int-amqp:inbound-channel-adapter 上有一个 receive-timeout="59000"，我希望它能在超过超时的任何地方使线程超时？

我现在注意到 int-http:outbound-gateway 上有一个 reply-timeout 属性，我应该设置它吗？

有什么想法吗？

    <int-amqp:inbound-channel-adapter id="amqpInCdbEvents"  channel="eventsAMQPChannel" channel-transacted="true"  transaction-manager="transactionManager" 
            queue-names="internal.events.queue" connection-factory="connectionFactory" 
            receive-timeout="59000" concurrent-consumers="${eventsAMQPChannel.concurrent-consumers}" 
            advice-chain="retryChain" auto-startup="false" /> 

     <int:channel id="eventsAMQPChannel" />

     <!--  CHAIN of processing for Asynch Processing of Events from intermediate Queue   -->

            <int:router expression="payload.eventType">

            </int:router>
    </int:chain>

                    extract-request-payload="true"

reply-timeout 是将回复发送到回复通道时的超时（如果它可以阻塞 - 例如，一个已满的有界队列通道）。

int-http:outbound-gateway call was stuck waiting for a http response getStatusCode()

您在可以配置到出站适配器的 ClientHttpRequestFactory 上设置了客户端超时 (readtimeout)...

/**
 * Create a new instance of the {@link RestTemplate} based on the given {@link ClientHttpRequestFactory}.
 * @param requestFactory HTTP request factory to use
 * @see org.springframework.http.client.SimpleClientHttpRequestFactory
 * @see org.springframework.http.client.HttpComponentsClientHttpRequestFactory
 */
public RestTemplate(ClientHttpRequestFactory requestFactory) {
    this();
    setRequestFactory(requestFactory);
}
