如何优雅地停止使用@RabbitListener 消费消息

问题描述

有没有办法优雅地停止 ListenerContainer 及其关联的 Consumers.

Is there a way to gracefully stop a ListenerContainer, and its associated Consumers.

我正在努力实现的目标.

1. 停止使用消息.
2. 优雅地停止 ListenerContainer.
3. 等待长时间运行的消费者，完成后确认.

我可以使用 consumer.stop() 停止 ListenerContainers，但活动的长时间运行的消费者不会成功完成，处理的消息也不会acked 并因此将在 ListenerContainer 恢复后再次处理.

I'm able to stop the ListenerContainers using consumer.stop(), but active long running consumers won't complete successfully, and processed messages won't be acked and will therefore be processed again, once the ListenerContainer has been resumed.

输出

Waiting for workers to finish.
Workers not finished.
Closing channel for unresponsive consumer: Consumer@6d229b1c

消息已处理，但未确认.

The message was processed, but not acked.

我或许可以使用 setForceCloseChannel(false) 实现正常关闭，但是否可以验证取消的消费者是否已完成?SimpleMessageListenerContainer.doShutDown() 有一个本地范围的列表cancelledConsumers".

I might be able to achieve a graceful shutdown using setForceCloseChannel(false), but is it possible to verify if the cancelled consumers has finished? SimpleMessageListenerContainer.doShutDown() has a local scoped List "canceledConsumers".

推荐答案

增加关机超时时间.

请参阅消息侦听器容器配置.

关机超时

当容器关闭时(例如，如果其封闭的 ApplicationContext 已关闭)，它会等待处理中的消息，直至达到此限制.默认为五秒.

When a container shuts down (for example, if its enclosing ApplicationContext is closed), it waits for in-flight messages to be processed up to this limit. Defaults to five seconds.

/**
 * The time to wait for workers in milliseconds after the container is stopped. If any
 * workers are active when the shutdown signal comes they will be allowed to finish
 * processing as long as they can finish within this timeout. Defaults
 * to 5 seconds.
 * @param shutdownTimeout the shutdown timeout to set
 */
public void setShutdownTimeout(long shutdownTimeout) {
