spring-rabbitmq

问题 This is the rabbitmq configuration that I have : <rabbit:admin connection-factory="rmqConnectionFactory"/> <bean id="**retryAdvice**" class="org.springframework.amqp.rabbit.config.StatefulRetryOperationsInterceptorFactoryBean"> <property name="retryOperations" ref="retryTemplate"/> </bean> <bean id="**retryTemplate**" class="org.springframework.retry.support.RetryTemplate"> <property name="retryPolicy" ref="simpleRetryPolicy"/> <property name="backOffPolicy"> <bean class="org.springframework

问题 I'm using SpringAMQP with Rabbit template. How to send messages directly to Queues omitting Exchange? How can i do it? 回答1: How can i do it? You can't; publishers don't know about queues; just exchanges and routing keys. However, all queues are bound to the default exchange ( "" ) with the queue name as its routing key. If you are using Spring AMQP's RabbitTemplate , it is configured to publish to the default exchange by default, so you can use convertAndSend("myQueue", "foo")` Or even...

问题 Its like " Houston we have a problem here " where I need to schedule/delay a message for 5 minutes after it fails on the first attempt to process an event. I have implemented dead letter exchange in this scenario. The messages on failing, route to the DLX --> Retry Queue and comes back to work queue after a TTL of 5 minutes for another attempt. Here is the configuration I am using: public class RabbitMQConfig { @Bean(name = "work") @Primary Queue workQueue() { return new Queue(WORK_QUEUE,

问题 I've an internet connection where the exit gateway periodically changes. I'm getting an event or callback notification to my spring application some seconds before this happens. I would like to stop my rabbit consumers and connections then and connect again after some seconds (when my network connection is back). I'm using the annotation based approach of spring amqp but i could also switch to another kind of implementation. I know that spring-amqp is doing a reconnect for me but i would like

问题 I did read this reference: https://www.rabbitmq.com/dlx.html, however it doesn't resolve my doubts, namely: In case of accepting message there is no problem - spring-rabbitmq send ack and everthing is fine, DLX doesn't know about acked message. The problem is in case rejecting answer, namely what about throwing MessageConverterException ? This message is removed or moved to DLX ? And what about in case other exception ? For example Exception ? It is removed/requeued/moved to DLX ? Edit after

问题 I am using RabbitMQ with Spring AMQP large message (>100MB, 102400KB) small bandwidth (<512Kbps) low heartbeat interval (10 seconds) single broker It will take >= 200*8 seconds to consume the message, which is more than my heartbeat interval. From https://stackoverflow.com/a/42363685/418439 If the message transfer time between nodes (60seconds?) > heartbeat time between nodes, it will cause the cluster to disconnect and the loose the message Will I also face the disconnection issue even I am

问题 I have developed asynchronous Spring Cloud Stream services, and I am trying to develop an edge service that uses @MessagingGateway to provide synchronous access to services that are async by nature. I am currently getting the following stack trace: Caused by: org.springframework.messaging.core.DestinationResolutionException: no output-channel or replyChannel header available at org.springframework.integration.handler.AbstractMessageProducingHandler.sendOutput(AbstractMessageProducingHandler

问题 So, this is new question related to this one I have created a case where ListenerContainer is actually run before @Bean with phase 0, even though it has phase Integer.MAX_INT . Here is the code: import java.util.ArrayList; import java.util.Arrays; import java.util.List; import org.springframework.amqp.core.QueueBuilder; import org.springframework.amqp.rabbit.annotation.Exchange; import org.springframework.amqp.rabbit.annotation.Queue; import org.springframework.amqp.rabbit.annotation

问题 I am trying to use a RPC AMQP RabbitMQ queue to send and receive messages. The problem is that I have set a setReplyTimeout value. When that happens I get a "org.springframework.amqp.AmqpRejectAndDontRequeueException: Reply received after timeout". I have a DLQ set up on the incoming queue, but it appears that the exception is received when spring tries to return the message on its queue that is automatically created. Thus how can I handle exceptions when sending messages back to a producer?

问题 I have a scenario where I am consuming messages from queues using SimpleMessageListenerContainer . When any of these subscribed queues got deleted, I would like to get notification or events. SimpleMessageListenerContainer simpleMessageListenerContainer = new SimpleMessageListenerContainer(cachingConnectionFactory); simpleMessageListenerContainer.setQueueNames( "testQueue1","testQueue2","testQueue3"); simpleMessageListenerContainer.start(); 回答1: There is currently no event published when a
