Question

我有一个简单的弹簧靴1.5.22 + amqp的示例，问题是队列不是动态创建的，而是应该动态创建的。

@Component
class ReceiverComponent {

@RabbitListener(queues = 'spring-boot-queue-2')
public void receive_2(String content) {
    System.out.println("[ReceiveMsg-2] receive msg: " + content);
}

@Component
class SenderComponent {

@Autowired
private AmqpAdmin amqpAdmin;

// The default implementation of this interface is RabbitTemplate, which 
currently has only one implementation.
@Autowired
private AmqpTemplate amqpTemplate;

/**
 * send message
 *
 * @param msgContent
 */
public void send_2(String msgContent) {
    amqpTemplate.convertAndSend(RabbitConfig.SPRING_BOOT_EXCHANGE, 
RabbitConfig.SPRING_BOOT_BIND_KEY, msgContent);
}

@Configuration
class RabbitConfig {

// Queue name
public final static String SPRING_BOOT_QUEUE = "spring-boot-queue-2";
// Switch name
public final static String SPRING_BOOT_EXCHANGE = "spring-boot-exchange- 
2";
// Bound values
public static final String SPRING_BOOT_BIND_KEY = "spring-boot-bind-key- 
2";
}

我遇到的错误是：

原因：com.rabbitmq.client.ShutdownSignalException：频道错误；协议方法：#method（reply-code = 404，Reply-text = NOT_FOUND-虚拟主机'/'中没有队列'spring-boot-queue-2'，class-id = 50，method-id = 10）

它是否必须在Rabbitmq上执行某些操作？安装的版本是3.7.13，我的数据是：

spring:
# Configure rabbitMQspring:
rabbitmq:
  host: 127.0.0.1
  port: 5672
  username: guest
  password: guest

你能放吗：

@Bean
public Queue queue() {
    return new Queue("spring-boot-queue-2'");
}

您的班级上用@Configuration注释？

在运行时未创建RabbitMQ队列
