我正在尝试启动一个Sping Boot 应用程序,该应用程序具有通过此配置类配置的RabbitMQ:
@Configuration
public class RabbitConfig implements RabbitListenerConfigurer {
public static final String AMQP_EXCHANGE_NAME = "test-queue";
@Bean
public Exchange accessExchange() {
return new DirectExchange(AMQP_EXCHANGE_NAME);
}
@Bean
public Binding binding(Queue queue, DirectExchange exchange) {
return BindingBuilder.bind(queue).to(exchange).with(AMQP_EXCHANGE_NAME);
}
@Bean
public Jackson2JsonMessageConverter producerJackson2MessageConverter() {
return new Jackson2JsonMessageConverter();
}
@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 DefaultMessageHandlerMethodFactory messageHandlerMethodFactory() {
DefaultMessageHandlerMethodFactory factory = new DefaultMessageHandlerMethodFactory();
factory.setMessageConverter(consumerJackson2MessageConverter());
return factory;
}
@Override
public void configureRabbitListeners(RabbitListenerEndpointRegistrar registrar) {
registrar.setMessageHandlerMethodFactory(messageHandlerMethodFactory());
}
字符串
但是我得到了错误no queue 'test-queue' in vhost '/'
:
Caused by: com.rabbitmq.client.ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=404, reply-text=NOT_FOUND - no queue 'test-queue' in vhost '/', class-id=50, method-id=10)

只有在定义了以下侦听器时才会出现此问题:
@Transactional
@RabbitListener(queues = RabbitConfig.AMQP_EXCHANGE_NAME)
public void doSomething(TestDTO dto) {
...
}

似乎我试图从队列中消费,但队列没有创建。如果我通过RabbitMQ Management接口创建队列,则不会发生错误。
有没有一种方法可以自动创建这个队列,这样我就不会得到这个错误?

您没有显示
Queue
bean,您的配置中似乎也没有RabbitAdmin
(自动声明队列、交换、绑定所需)。请参阅配置Broker。
