Java Rabbit SimpleMessageListenerContainer赢得'；不要关机
从开始，我们有一个兔子凭据失效的场景，我们需要在Java Rabbit SimpleMessageListenerContainer赢得'；不要关机,java,rabbitmq,spring-amqp,Java,Rabbitmq,Spring Amqp,从开始，我们有一个兔子凭据失效的场景，我们需要在CachingConnectionFactory上调用resetConnection（），以获取一组新的凭据 我们在一个ShutdownSignalException处理程序中这样做，它基本上可以工作。不起作用的是，我们还需要重新启动侦听器。我们有以下几种： @RabbitListener( id = ABC, bindings = @QueueBinding(value = @Queue(value="myQ", durable=
CachingConnectionFactoryresetConnection（）ShutdownSignalException@RabbitListener(
id = ABC,
bindings = @QueueBinding(value = @Queue(value="myQ", durable="true"),
exchange = @Exchange(value="myExchange", durable="true"),
key = "myKey"),
containerFactory = "customQueueContainerFactory"
)
public void process(...) {
...
}
@Autowired RabbitListenerEndpointRegistry registry;
@Autowired CachingConnectionFactory connectionFactory;
@Override
public void shutdownCompleted(ShutdownSignalException cause) {
refreshRabbitMQCredentials();
}
public void refreshRabbitMQCredentials() {
registry.stop(); // do this first
// Fetch credentials, update username/pass
connectionFactory.resetConnection(); // then this
registry.start(); // finally restart
}
SimpleMessageListenerContainerdoShutdown（）阻塞队列消费者通道ChannelN.basicCancel（）任务执行器Executors.newCachedThreadPool（）shutdownNow（）ShutdownSignalException更新2: 这似乎是某种种族状况。移除容器停止/启动后，如果我向
SimpleMessageListenerContainer.restart（）resetConnection（）跑过去，然后释放断点，那么我可以看到事情开始恢复：

在这种情况下，我现在必须解决如何延迟容器重新启动，直到刷新完成（即我的ShutdownSignalException
处理程序完成），或者以某种方式使刷新阻塞
更新3:
我的整个问题（这是一个症状）通过以下方式得到解决：根本不清楚为什么频道会报告为开放；这对我来说很好；它在删除用户foo
后恢复

但是，您确实不需要停止/启动注册表，只需使用新凭据重新配置连接工厂，然后调用resetConnection（）
；集装箱会恢复的。谢谢。我希望我不必执行停止/启动操作，但集装箱无论如何都无法恢复。我想知道这是否是因为消费者在CachingConnectionFactory
设置其凭据之前重新启动。此外，如果我降低Spring AMQP日志记录以进行调试，它似乎仍在获取旧的细节。似乎没有任何“重置”的情况发生。似乎是比赛条件影响了我而不是你。我用2.0.2进行了测试，但我不记得有任何改变会影响这一点。下周我将尝试使用1.7.x。如果将容器上的possibleAuthenticationFailureFailtal
设置为false
，是否会看到不同的行为？感谢您的关注。经过测试，该标志在此无效。看起来容器和ShutdownSignalException
处理程序之间确实出现了错位：只有在线程之间共享一些状态，我才能在容器重新启动之前尝试重新排序刷新…我刚刚用1.7.6测试过，没有问题；如果你能举出一个小例子来说明这个问题，我会找出问题所在。
