我正在使用Spring Boot和RabbitMQ开发基于Spring云的应用程序。我正在尝试使用FanoutExchange
在RabbitMQ中创建一个交换。 我的要求是向多个队列发送相同的消息,因此我使用的是FanoutExchange
但是将异常视为:
Caused by: com.rabbitmq.client.ShutdownSignalException: channel error;
protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED
- inequivalent arg 'type' for exchange 'rkk_exchange1' in vhost
'': received 'fanout' but current is 'topic',
class-id=40, method-id=10)
下面是代码(配置文件):
@Configuration
@Profile("cloud")
public class MultiListenerRabbitConfig extends AbstractCloudConfig{
private static final String QUEUE_NAME1="rk.rkk_queue1";
private static final String QUEUE_NAME2="rk.rkk_queue2";
private static final String EXCHANGE_NAME="rkk_exchange1";
private static final int PORT = 1;
@Bean
public CachingConnectionFactory cachingConnectionFactory(){
CloudFactory cloudFactory = new CloudFactory();
Cloud cloud = cloudFactory.getCloud();
List<ServiceInfo> listServices = cloud.getServiceInfos();
AmqpServiceInfo serviceInfo = (AmqpServiceInfo) cloud.getServiceInfo(cloud.getServiceInfos().get(0).getId());
CachingConnectionFactory cachingConnectionFactory = new CachingConnectionFactory();
cachingConnectionFactory.setUsername(serviceInfo.getUserName());
cachingConnectionFactory.setPassword(serviceInfo.getPassword());
cachingConnectionFactory.setVirtualHost(serviceInfo.getVirtualHost());
cachingConnectionFactory.setHost(serviceInfo.getHost());
cachingConnectionFactory.setPort(PORT);
cachingConnectionFactory.setRequestedHeartBeat(30);
cachingConnectionFactory.setConnectionTimeout(30000);
return cachingConnectionFactory;
}
@Bean
public RabbitTemplate rabbitTemplate(){
System.out.println("-----------------**************------------------ Create Rabbit Template");
RabbitTemplate template = new RabbitTemplate(cachingConnectionFactory());
return template;
}
@Bean
public RabbitAdmin rabbitAdmin(){
//Set up queue, exchanges and bindings
RabbitAdmin admin = new RabbitAdmin(cachingConnectionFactory());
Queue queue1 = new Queue(QUEUE_NAME1);
admin.declareQueue(queue1);
//For a Fanout Exchange, any Queue bound to that Exchange will receive any message sent to that Exchange
FanoutExchange exchange = new FanoutExchange(EXCHANGE_NAME);
admin.declareExchange(exchange);
Binding binding = BindingBuilder.bind(queue1).to(exchange);
admin.declareBinding(binding);
return admin;
}
}
放置堆栈跟踪:

注意:此应用正在使用TopicExchange
,但我的要求是使用FanoutExchange
答案 0 :(得分:3)
您无法更改交换类型(它目前是主题交换);你必须删除它并重新添加它。
此外,您应该在@Bean
定义中不做工作(声明) - 应用程序上下文尚未构建,可能会导致问题。相反,定义bean然后稍后获取对它的引用来进行声明。
@Bean
public RabbitAdmin rabbitAdmin(){
return new RabbitAdmin(cachingConnectionFactory());
}
完成上下文后,您需要执行声明。
