您需要在配置中定义队列本身
@Bean
public org.springframework.amqp.core.Queue myQueue() {
final boolean isDurable = true;
final boolean isExclusive = false;
final boolean autoDelete = false;
return new org.springframework.amqp.core.Queue(QUEUE_NAME, isDurable, isExclusive, autoDelete);
}
您需要绑定队列和交换，请尝试下面的RabbitmqConfig
@Configuration
public class RabbitmqConfig {
private static final String QUEUE_NAME = "testqueue";
@Bean
Queue queue() {
return new Queue(QUEUE_NAME, false);
}
@Bean
TopicExchange exchange() {
return new TopicExchange("spring-boot-exchange", true, false);
}
@Bean
Binding binding(Queue queue, TopicExchange exchange) {
return BindingBuilder.bind(queue).to(exchange).with(QUEUE_NAME);
}
}
您需要一个
RabbitAdmin@Bean如果您使用Spring Boot，它将自动为您注册模板和管理员。嗨，Jeff，感谢您的回复，我仍然收到相同的错误：由com.rabbitmq.client.ShutdownSignalException引起：通道错误；协议方法：#方法（回复代码=404，回复文本=未找到-vhost'9cc1b4db-636e-4251-bb68-c7ed7f3be1d3'中没有队列'testqueue'，类id=60，方法id=70）您是否将其放入RabbitConfig并使用配置文件云运行？（-Dspring.profiles.active=cloud作为大多数IDE中的运行参数或vm参数）Ya Jeff，我已经粘贴了更新的RabbitConfig.javaYou
BindingQueueExchangerabbitmplate.setQueue（队列名称）来自你的代码。亚丽萍，那样做了，运气不好！我不知道为什么它仍然给出这个错误。@RiteshKaushik你能去rabbitmq管理员那里检查队列/通道吗？
