Spring boot 使用默认exchange声明第二个队列会产生错误

弹簧靴1.5.15

当我声明一个队列时，该队列被声明，发送/接收工作正常。 如果我添加第二个和后续队列，则会记录一个错误，队列会被重新声明5次，最后应用程序无法启动

Spring引导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);
        }
}

有错误的日志：

好吧，这是一个愚蠢的想法

我假设每次声明队列时都会从头创建一个队列，但在我的配置中，情况并非如此

事实上，它已经存在了一个不同的耐久性参数-这正是错误消息试图告诉我的

解决方案：我使用AmqAdmin.deleteQueue将其删除

portal.user队列已经存在，其设置与您在此处配置的不同，这就是错误消息告诉您的内容。您不能重新声明队列。同意，这是log msg的建议，但我仔细检查了它以确保情况并非如此。更新问题
