Java 如何设置spring rabbitmq侦听器'；s接收消息的速率

我正在使用spring rabbitmq，并且我可以成功地获取消息。 但是当我调试时，我发现侦听器创建了一个线程，它会询问 每1秒发送一次消息。我认为速率太高。我要做的是将速率设置为1分钟或任何其他时间。 我搜索了很多，但都不起作用

My springrabbit.xml：

<rabbit:listener-container connection-factory="connectionFactory"  message-converter="jsonMessageConverter" >
        <rabbit:listener queues="notification" ref="messageReceiver"/>
    </rabbit:listener-container>

调试结果如下所示：

您可以增加

receiveTimeout

-请参阅

但是，容器对

stop（）

请求的响应性会降低

我认为您过于担心轮询率——轮询用于暂存传递消息的内部队列的开销非常小

如果只是要删除的日志“噪音”（在调试时），请将

org.springframework.amqp.rabbit.listener.BlockingQueueConsumer

log类别设置为

INFO

或

WARN

即将发布的2.0版本有一个新的

DirectMessageListenerContainer

，它不轮询内部队列，并消除了此问题

编辑

侦听器仍然每隔1s向rabbitmq请求消息

如果您仍然每隔1s看到一次调试消息，则说明您没有正确配置

receiveTimeout

；它不是“询问rabbitmq”消息，线程在等待

receiveTimeout

（并发现rabbit没有发送新消息）后被唤醒，因此它可以对

stop（）

作出反应；然后它再次休眠，直到新消息到达或再次超时。如果没有可用的消息，则不会与代理进行交互-消息由代理推送

也许您误解了侦听器容器的用途。它适用于消息驱动的应用程序—您不能“减慢”消息到达的速度—它们是由代理推送的

---

如果您希望每分钟只接收一次消息，则应使用

rabbitmplate

receive（）

（或

receiveAndConvert（）

）方法，而不是消息侦听器容器。

谢谢，我阅读了文档并尝试了[receiveTimeout]，然后发现只有在收到消息时才会发生此情况，否则，侦听器仍然每隔1s向rabbitmq请求消息。我想设置侦听器每1分钟请求一次消息。可以这样做吗？谢谢。天哪，我误解了。谢谢，我用receiveAndConvert（）再试了一次，效果很好。
