Spring Boot RabbitMQ Producer Consumer Example

Table of Contents


In this tutorial I will show you how to build producer consumer example using Spring Boot and RabbitMQ. This is also called point-to-point messaging model as there are only one producer or sender and only one consumer or receiver.

RabbitMQ is a message broker; it accepts, stores and forwards binary data or messages. A message producer, a message consumer and a queue participate in this message processing event.

A message producer sends the message to the consumer through queue. A message is stored inside a queue. A queue is bound by host’s memory and disk limit. So, it’s a large memory buffer.

Many producers can send messages to a single queue and many consumers can consume messages from a single queue.

It is not necessary that producer, consumer and broker will reside on the same host. Even an application can be both producer and consumer.

In this example tutorial, I am going to use spring amqp library and a producer that sends a single message and a consumer that receives a single message from the queue & prints it out in the console.


Java 1.8+, Maven 3.8.2, Spring Boot 2.6.2, Spring Boot AMQP 2.6.2, RabbitMQ Server 3.9.4 – 3.9.13

Project Setup

I am going to create maven based project for this example and the following pom.xml file can be used for your project too.

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0"
	xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">










The application.properties file has the queue name declaration and this file is kept in the class path folder src/main/resources.



A Producer or Sender class that sends a message to a queue.

package com.roytuts.spring.rabbitmq.producer;

import org.springframework.amqp.core.Queue;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

public class Producer {

	private Queue queue;

	private RabbitTemplate rabbitTemplate;

	public void sendMsg(final String msg) {
		rabbitTemplate.convertAndSend(queue.getName(), msg);
		System.out.println("Sent: " + msg);


The above class has a method sendMsg() that takes a string as an argument and sends it to the broker or queue. To send the message I have used RabbitTemplate and Queue.


A Consumer or Receiver class that consumes message from the broker or queue upon arrival.

package com.roytuts.spring.rabbitmq.consumer;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@RabbitListener(queues = "${queue.name}")
public class Consumer {

	public void receiveMsg(final String msg) {
		System.out.println("Received: " + msg);


The above class uses annotation @RabbitListener with queue name, so once a message arrives in the queue, the message will be consumed by the consumer.


A Config class that configures beans for Queue, Producer (if required) and Consumer (if required).

package com.roytuts.spring.rabbitmq.producer.consumer.config;

import org.springframework.amqp.core.Queue;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

import com.roytuts.spring.rabbitmq.consumer.Consumer;
import com.roytuts.spring.rabbitmq.producer.Producer;

public class Config {

	private String queueName;

	public Queue queue() {
		return new Queue(queueName);

	// @Bean
	public Producer producer() {
		return new Producer();

	// @Bean
	public Consumer consumer() {
		return new Consumer();


If you are not using @Component annotation on Producer and Consumer classes then you can declare them as beans using @Bean annotation (omit the comment) in the Config class.

Spring Boot RabbitMQ Main Class

A class that has a main method and @SpringBootApplication annotation will deploy the application in embedded Tomcat server.

package com.roytuts.spring.rabbitmq;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import com.roytuts.spring.rabbitmq.producer.Producer;

public class RabbitMqProducerConsumerApp implements CommandLineRunner {

	private Producer producer;

	public static void main(String[] args) {
		SpringApplication.run(RabbitMqProducerConsumerApp.class, args);

	public void run(String... args) throws Exception {
		producer.sendMsg("This message passes through RabbitMQ broker");


The above class uses CLI interface to run the application because I am not using anything for the web application.

Testing Producer Consumer App

Once you run the above main class, you will see that the producer sent a message and consumer received a message:

Sent: This message passes through RabbitMQ broker
Received: This message passes through RabbitMQ broker

The following queue gets created in the RabbitMQ server:

rabbitmq producer consumer

Hope you got an idea how to work with point-to-point messaging model using RabbitMQ broker.
