Question

Spring Boot 1.5.15

当我声明一个队列时，该队列即被声明并且发送/接收工作正常。如果我添加第二个（和后续）队列，则会记录错误，重新声明队列5次，最后应用程序无法启动。

Spring Boot RabbitMQ配置：

    @Configuration
    public class RabbitConfig implements RabbitListenerConfigurer {

        @Autowired
        private ObjectMapper mapper;

        @Bean
        Queue crmAppealQueue(@Value("${app.queues.portalAppeal}") String queueName) {
            return new Queue(queueName, false);
        }

        @Bean
        Queue portalUserQueue(@Value("${app.queues.portalUser}") String queueName) {
            return new Queue(queueName, false);
        }

        @Override
        public void configureRabbitListeners(RabbitListenerEndpointRegistrar registrar) {
            registrar.setMessageHandlerMethodFactory(messageHandlerMethodFactory());
        }

        @Bean
        MessageHandlerMethodFactory messageHandlerMethodFactory() {
            DefaultMessageHandlerMethodFactory messageHandlerMethodFactory = new DefaultMessageHandlerMethodFactory();
            messageHandlerMethodFactory.setMessageConverter(consumerJackson2MessageConverter());
            return messageHandlerMethodFactory;
        }

        @Bean
        public MappingJackson2MessageConverter consumerJackson2MessageConverter() {
            return new MappingJackson2MessageConverter();
        }

        @Bean
        public RabbitTemplate rabbitTemplate(final ConnectionFactory connectionFactory) {
            final RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
            rabbitTemplate.setMessageConverter(producerJackson2MessageConverter());
            return rabbitTemplate;
        }

        @Bean
        public Jackson2JsonMessageConverter producerJackson2MessageConverter() {
            return new Jackson2JsonMessageConverter(mapper);
        }
}

错误日志：

It will be redeclared if the broker stops and is restarted while the connection factory is alive, but all messages will be lost.

如果注释了一个队列声明，则日志显示仅声明了一个队列，并且应用程序继续启动（也就是说，其他地方未声明另一个队列）

好吧，那真是个愚蠢的家伙（很可能是这样）。

我假设每次声明队列都是从头开始创建的，这与我的配置不同。

实际上，它存在一个不同的耐用性参数-正是msg试图告诉我的错误。

解决方案：我使用AmqAdmin.deleteQueue()

删除了它

使用默认交换声明第二个队列会产生错误
