偶发性rabbitmq出问题或者认为操作错误，访问不了queue，导致消费端停止消费

	Stopping container from aborted consumer

跟踪

SimpleMessageListenerContainer

catch (QueuesNotAvailableException ex) {
				logger.error("Consumer received fatal=" + SimpleMessageListenerContainer.this.mismatchedQueuesFatal
						+ " exception on startup", ex);
				if (SimpleMessageListenerContainer.this.missingQueuesFatal) {
					logger.error("Consumer received fatal exception on startup", ex);
					this.startupException = ex;
					// Fatal, but no point re-throwing, so just abort.
					aborted = true;
				}
				publishConsumerFailedEvent("Consumer queue(s) not available", aborted, ex);
			}

SimpleMessageListenerContainer.this.missingQueuesFatal = true 将aborted

查代码跟踪，如下配置设置

import org.springframework.amqp.rabbit.config.SimpleRabbitListenerContainerFactory;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.boot.autoconfigure.amqp.SimpleRabbitListenerContainerFactoryConfigurer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;


@Configuration
public class RabbitConfiguration {

    @Bean
    public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory(
            SimpleRabbitListenerContainerFactoryConfigurer configurer,
            ConnectionFactory connectionFactory) {
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();

        //Whether to fail if the queues declared by the container are not available on the broker and/or whether to stop the container if one or more queues are deleted at runtime.
        factory.setMissingQueuesFatal(false);
        configurer.configure(factory, connectionFactory);
        return factory;
    }

}

至此涉及queue访问失败场景 会一直重试 直到可用，默认5次
