我对Spring云流和RabbitMQ有疑问。我不知道为什么，但我经常出现这个问题，我们经常失去与兔子的连接几秒钟并重新建立连接。
这是堆栈跟踪：
[container-1] WARN org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer - Consumer raised exception, processing can restart if the connection factory supports it
com.rabbitmq.client.ShutdownSignalException: connection error

以下是我们使用的应用程序属性：
spring.rabbitmq.host=rabbit_host
spring.rabbitmq.port=rabbit_port
spring.rabbitmq.username=rabbit_user
spring.rabbitmq.password=rabbit_password
spring.rabbitmq.ssl.enabled=true
rabbit.queues=someQueue
spring.cloud.stream.bindings.output.content-type=application/json
rabbit.enable-retry=true
spring.cloud.stream.defaultBinder=rabbit
spring.cloud.stream.bindings.input.binder=kafka
spring.cloud.stream.bindings.output.binder=rabbit
spring.rabbitmq.requested-heartbeat=60
我们正在使用AggregateApplicationBuilder来协调我们的流。
public static void main(String[] args) {
new AggregateApplicationBuilder(SpringApplication.run(OurApplication.class)).from(RabbitSourceConfiguration.class).from(ourTransformer.class).to(ourSink.class).run(args);
}
如果他们能够自行解决问题，我们通常会遇到一些间歇性的连接问题，但这是我们的主要问题。 在我们的生产环境中，我们实际上最终会在一段时间后永久失去连接。以下是发生该问题时的以下堆栈跟踪。

我们认为这可能是因为兔子服务器或haproxy在闲置一段时间之后正在倾倒我们的连接，但随后我添加了＃34; requested-heartbeat＆＃34;，我们仍然遇到问题。< / p>
对于导致此问题的原因或原因，任何人都有任何想法或线索？任何帮助或方向将不胜感激。
谢谢！
