java - Spring Integration AMQP - 消息偶尔未确认，需要超时吗？

Question

我有一个入站 RabbitMQ channel 适配器，每天成功处理 3000 条消息，但是偶尔我会在 RabbitMQ 管理控制台中看到未确认的消息计数为 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转移到 DLQ，这对于大多数异常(exception)情况都效果很好。

过去几周内发生了两次未确认的情况，其中一次我能够进行线程转储并看到 int-http:outbound-gateway 调用被卡住等待 http 响应 getStatusCode()

我在 int-amqp:inbound-channel-adapter 上有一个 receive-timeout="59000"，我希望它会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 上有一个回复超时属性，我应该设置它吗？

有什么想法值得赞赏吗？

reply-timeout 是将回复发送到回复 channel 时的超时(如果它可以阻塞 - 例如，有界队列 channel 已满)。

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中的 ClientHttpRequestFactory 上设置客户端超时 (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);
}
