Question

我使用Spring AMQP来收听消息（配置有listener-container, service-activator, chain, bridge & aggregators）。在应用程序启动时，AMQP开始阅读我们不想要的消息。我试过auto-startup=false但它不起作用。我错过了什么吗？

此外，如果它确实有效，那么我如何以编程方式再次启动它们呢？我试过了listenerContainer.start();。聚合器＆amp;其他

以下是我的配置：

行。谢谢你的配置！

不确定为什么你需要AMQP-bascked频道，但主要问题就在那里。

但要注意，<int-amqp:channel>也有auto-startup="false"选项。

您将准备好接收来自AMQP的数据，start()只需要id这些频道。

AMQP防止自动消息读取
