在spring-boot中使用rabbitmq时，vhost'/'中没有队列'dev_pms2invoi_queue'

Question

我想在spring-boot项目中使用rabbitmq，只是使用注释，这是我的mq配置代码，

@Configuration
public class RabbitMqConfig {
    @Bean(value = "pmsMqConnectionFactory")
    public ConnectionFactory pmsMqConnectionFactory(){
        CachingConnectionFactory connectionFactory=new CachingConnectionFactory();
        connectionFactory.setAddresses(pmsMqServerAddress);
        connectionFactory.setVirtualHost(pmsMqServerVirtualHost);
        connectionFactory.setUsername(pmsMqServerUserName);
        connectionFactory.setPassword(pmsMqServerPassword);
        return connectionFactory;
    }
    @Bean(value = "pmsConsumerQueue")
    public Queue pmsConsumerQueue(){
        Queue consumerQueue=new Queue(pmsMqConsumerQueue,pmsMqQueuePersist);

        return consumerQueue;
    }
    @Bean(value = "pmsConsumerExchange")
    public Exchange pmsConsumerExchange(){
        Exchange consumerExchange=new DirectExchange(pmsMqConsumerExchangeName,pmsMqQueuePersist,false);
        return consumerExchange;
    }
    @Bean(value = "pmsConsumerMessageBinding")
    public Binding pmsConsumerMessageBinding(@Qualifier("pmsConsumerQueue") Queue queue,
                                                  @Qualifier("pmsConsumerExchange") Exchange exchange){
        return BindingBuilder.bind(queue).to(exchange).with("").noargs();
    }
    @Bean(value = "pmsMessageListenerContainer")
    public SimpleMessageListenerContainer pmsMessageListenerContainer(@Qualifier("pmsMqConnectionFactory") ConnectionFactory connectionFactory,
                                                                      @Qualifier("pmsMqConsumer") PmsMqConsumer pmsMqConsumer,@Qualifier("pmsConsumerQueue")Queue queue){
        SimpleMessageListenerContainer container=new SimpleMessageListenerContainer();
        container.setConnectionFactory(connectionFactory);
        container.setMessageListener(pmsMqConsumer);
        container.setQueues(queue);
        container.setAcknowledgeMode(AcknowledgeMode.MANUAL);
        return container;
    }
}

当我启动应用程序时，发生错误：

上面说没有队列，但是如何用注解创建呢？我的代码有错误吗？

Answer 1

由于您已经声明了自己的连接工厂，因此您需要声明一个使用该连接工厂的RabbitAdmin @Bean。

如果你使用 boot 的属性驱动配置，它会自动为你配置一个连接工厂和RabbitAdmin。
