我有两个不同的交换机，我希望我的队列与之绑定，下面的方法不起作用
配置文件-
@Configuration
public class RabbitMQConfiguration {
@Value("${spring.rabbitmq.host}")
private String host;
@Value("${spring.rabbitmq.username}")
private String username;
@Value("${spring.rabbitmq.password}")
private String password;
@Value("${spring.rabbitmq.batching.queue}")
private String batchingQueue;
@Value("${spring.rabbitmq.publishing.queue}")
private String publishingQueue;
@Value("${spring.rabbitmq.exchange}")
private String exchange;
@Value("${spring.rabbitmq.delayed.exchange}")
private String delayedExchange;
@Value("${spring.rabbitmq.batching.routingkey}")
private String batchingRoutingKey;
@Value("${spring.rabbitmq.publishing.routingkey}")
private String publishingRoutingKey;
@Bean
CachingConnectionFactory connectionFactory() {
CachingConnectionFactory cachingConnectionFactory = new CachingConnectionFactory(host);
cachingConnectionFactory.setUsername(username);
cachingConnectionFactory.setPassword(password);
return cachingConnectionFactory;
}
@Bean
public MessageConverter jsonMessageConverter() {
return new Jackson2JsonMessageConverter();
}
@Bean
public RabbitTemplate rabbitTemplate(ConnectionFactory connectionFactory) {
final RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
rabbitTemplate.setMessageConverter(jsonMessageConverter());
return rabbitTemplate;
}
@Bean
Queue batchingQueue() {
return new Queue(batchingQueue, true);
}
@Bean
Queue publishingQueue() {
return new Queue(publishingQueue, true);
}
@Bean
Exchange myExchange() {
return ExchangeBuilder.directExchange(exchange).durable(true).build();
}
@Bean
public CustomExchange delayExchange() {
Map<String, Object> args = new HashMap<>();
args.put("x-delayed-type", "direct");
return new CustomExchange(delayedExchange, "x-delayed-message",true, false,args);
}
@Bean
Binding batchingBinding() {
return BindingBuilder
.bind(batchingQueue())
.to(myExchange())
.with(batchingRoutingKey)
.noargs();
}
@Bean
Binding publishingBinding() {
return BindingBuilder
.bind(publishingQueue())
.to(delayExchange())
.with(publishingRoutingKey)
.noargs();
}
}
当两个队列都与1个交换机(myExchange(绑定时，它可以完美地工作，但当我使用2个交换机运行此应用程序时，我会收到以下日志，最终它无法连接。请帮助我了解如何解决此

我意识到这是因为我还没有启用插件。
我需要先启用这个插件，然后它就工作了。
rabbitmq插件启用rabbitmq_delayerd_message_exchange
只要把它放出来，就会有其他人面对这个
