spring-amqp

问题 I have a Spring @Configuration class that creates and registers RabbitMQ queues as follows: @Amqp @Configuration public class AmqpConfiguration { @Bean ConnectionFactory connectionFactory() { CachingConnectionFactory connectionFactory = new CachingConnectionFactory(HOST); connectionFactory.setUsername(USERNAME); connectionFactory.setPassword(PASSWORD); connectionFactory.addConnectionListener(brokerListener); return connectionFactory; } @Bean SimpleMessageListenerContainer

问题 I have a Spring Boot application and my goal is to declare queues, exchanges, and bindings on application startup. The application will produce messages to various queues there will be no consumers on the application. I have included those dependencies on my pom.xml <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> <version>2.3.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.amqp</groupId> <artifactId>spring

问题 I have a use case where I need to consume messages from queues which are discovered at runtime. Here I have a config class and the listener class. I have defined a consumer for the two existing queues and want to consume messages from new queues which may be discovered at runtime and follow the same naming convention i.e. queue.animals.* Also, I have another service which will send me the newly discovered queue name on a queue named "newQueues". This approach can be changed if not needed and

问题 I use RabbitMQ and Spring AMQP to send messages. I have this snippet: rabbitTemplate.convertAndSend(exchange, key, object); This works when I operate on a single VHOST . I have to receive messages from 1 queue and resend them to N exchanges (on many different VHOST s). How can I do it in Spring AMQP (ver 1.2) ? Is there anything better than manually defined <rabbit:connection-factory> (for each VHOST) and related elements in my xml context? 回答1: We added support for that in 1.3. See Routing

问题 From spring boot tutorial: https://spring.io/guides/gs/messaging-rabbitmq/ They give an example of creating 1 queue and 1 queue only, but, what if I want to be able to create more then 1 queue? how would it be possible? Obviously, I can't just create the same bean twice: @Bean Queue queue() { return new Queue(queueNameAAA, false); } @Bean Queue queue() { return new Queue(queueNameBBB, false); } You can't create the same bean twice, it will make ambiguous. 回答1: Give the bean definition factory

问题 I have a web-app that posts messages on RabbitQueue using spring. I have turned on Publisher confirms and returns enabled and I'm using spring rabbit:template.
