To integrate RabbitMQ with Spring Boot, you will need to do the following:

  1. Add the following dependency to your Maven pom.xml file:
1
2
3
4
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-amqp</artifactId>
</dependency>


  1. Add the following configuration to your application.properties file:
1
2
3
4
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest


  1. Create a configuration class and annotate it with @EnableRabbit. This will enable the detection of RabbitMQ configuration in the Spring Environment and application context.

2
3
4
5
@Configuration
@EnableRabbit
public class RabbitMQConfig {
    //...
}


  1. Create a message listener container factory bean and configure it to use the connection factory.

2
3

@Bean
public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory(ConnectionFactory connectionFactory) {
    SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
    factory.setConnectionFactory(connectionFactory);
    return factory;
}


  1. Create a message listener and annotate it with @RabbitListener. This will enable the detection of message listener methods in the registered beans.

@Component
public class RabbitMQListener {
    @RabbitListener(queues = "queue-name")
    public void processMessage(String message) {
        //...
    }
}


That's it! You have successfully integrated RabbitMQ with Spring Boot.
