Spring JMS在同一应用程序中使用点对点和主题

Question

We are currently introducing ActiveMQ into our existing application which was running on a different Queueing system. Spring JMS is used to make use of the existing integration within the Spring framework.

Most of our applications use point-to-point (queue) communication, with the exception of one. It needs to be able to listen to the topic created by another producing application while publishing to multiple queues at the same time.

This means that application needs to support both Topics and Queues. However, when setting the global property

jms:
    pub-sub-domain: true

the setting is global and all queue subscribers are immediately subscribing to topics, which we can see in the ActiveMQ web interface.

Is there a way to configure the application to support both topics and queues at the same time?

The boot property is used to configure the default container factory used by @JmsListener methods, as well as to configure the JmsTemplate .

Simply override Boot's default container factory...

@Bean
public DefaultJmsListenerContainerFactory jmsListenerContainerFactory(
        DefaultJmsListenerContainerFactoryConfigurer configurer,
        ConnectionFactory connectionFactory) {

    DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
    configurer.configure(factory, connectionFactory);
    return factory;
}

and then add a second one

@Bean
public DefaultJmsListenerContainerFactory jmsTopicListenerContainerFactory(
        DefaultJmsListenerContainerFactoryConfigurer configurer,
        ConnectionFactory connectionFactory) {

    DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
    configurer.configure(factory, connectionFactory);
    factory.setPubSubDomain(true); << override the boot property
    return factory;
}

Then refer to the alternate factory in the @JmsListener for the topic.

Alternatively, if you don't have listeners for both types, set the property to true , but override Boot's JmsTemplate configuration.
