Messaging

Spring Boot offers a number of starters to support messaging. This section answers questions that arise from using messaging with Spring Boot.

Disable Transacted JMS Session

If your JMS broker does not support transacted sessions, you have to disable the support of transactions altogether. If you create your own JmsListenerContainerFactory, there is nothing to do, since, by default it cannot be transacted. If you want to use the DefaultJmsListenerContainerFactoryConfigurer to reuse Spring Boot’s default, you can disable transacted sessions, as follows:

  • Java

  • Kotlin

import jakarta.jms.ConnectionFactory;

import org.springframework.boot.autoconfigure.jms.DefaultJmsListenerContainerFactoryConfigurer;
import org.springframework.boot.jms.ConnectionFactoryUnwrapper;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jms.config.DefaultJmsListenerContainerFactory;

@Configuration(proxyBeanMethods = false)
public class MyJmsConfiguration {

	@Bean
	public DefaultJmsListenerContainerFactory jmsListenerContainerFactory(ConnectionFactory connectionFactory,
			DefaultJmsListenerContainerFactoryConfigurer configurer) {
		DefaultJmsListenerContainerFactory listenerFactory = new DefaultJmsListenerContainerFactory();
		configurer.configure(listenerFactory, ConnectionFactoryUnwrapper.unwrapCaching(connectionFactory));
		listenerFactory.setTransactionManager(null);
		listenerFactory.setSessionTransacted(false);
		return listenerFactory;
	}

}
import jakarta.jms.ConnectionFactory
import org.springframework.boot.jms.ConnectionFactoryUnwrapper
import org.springframework.boot.autoconfigure.jms.DefaultJmsListenerContainerFactoryConfigurer
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration
import org.springframework.jms.config.DefaultJmsListenerContainerFactory

@Configuration(proxyBeanMethods = false)
class MyJmsConfiguration {

	@Bean
	fun jmsListenerContainerFactory(connectionFactory: ConnectionFactory?,
			configurer: DefaultJmsListenerContainerFactoryConfigurer): DefaultJmsListenerContainerFactory {
		val listenerFactory = DefaultJmsListenerContainerFactory()
		configurer.configure(listenerFactory, ConnectionFactoryUnwrapper.unwrapCaching(connectionFactory))
		listenerFactory.setTransactionManager(null)
		listenerFactory.setSessionTransacted(false)
		return listenerFactory
	}

}

The preceding example overrides the default factory, and it should be applied to any other factory that your application defines, if any.
