春季AMQP老化消费者对RabbitMQ的PCF
春季AMQP老化消费者对RabbitMQ的PCF
提问于 2019-03-06 19:00:25
我们的团队在Spring使用云铸造连接器时遇到了一些问题。每当网络出现不稳定时，连接就会失败，那么AMQP似乎会尝试自动恢复，无法自动恢复，然后创建一个新的消费者。
问题是RabbitMQ似乎并没有取消老消费者的注册.因此，我们最终有40个消费者，而不是通常的one消费者。而且，我认为，由于无效消费者的数量，老消费者会收到一些消息，但不会运行我们的代码。因此，我们有一堆未加加的消息，直到应用程序重新启动并清除使用者列表。
--我不确定这是我们端的错误配置，还是错误。有什么主意吗？
以下是补充资料。
我们日志中的一小部分：

@Bean
@Primary

containerFactory.setConnectionFactory(connectionFactory());
containerFactory.setAutoStartup(true);
return containerFactory;

我们使用SpringBoot1.5.9、Framework4.3.6、AMQP1.7.4、RabbitMQ AMQP客户机4.0.3
从2.0版本开始，Spring禁用目标automaticRecoveryEnabled RabbitMQ ConnectionFactory：https://docs.spring.io/spring-amqp/docs/2.1.4.RELEASE/reference/#auto-recovery
由于您使用的版本是基于云连接器提供的RabbitMQ ConnectionFactory，所以需要显式禁用它：
@Bean
@Primary
public ConnectionFactory connectionFactory(){
ConnectionFactory connectionFactory = cloud().getSingletonServiceConnector(ConnectionFactory.class, null);
((CachingConnectionFactory) connectionFactory).getRabbitConnectionFactory().setAutomaticRecoveryEnabled(false);
return connectionFactory;
}您的解决方案将基于Spring提供的恢复机制。
