Sending Messages to Amazon SQS Using Spring Boot


What is Amazon SQS?

Amazon Simple Queue Service (SQS) is a fully managed message queuing service provided by AWS. It allows for the decoupling of components in a distributed system, ensuring reliable and secure message transmission.

Integrating SQS with Spring Boot offers a powerful way to build distributed, scalable applications. Spring Boot simplifies the development process, while SQS provides a robust backend for message queuing and asynchronous communication.

Use Cases:

  • Asynchronous Operations: Managing tasks such as data processing, or sending notifications without impacting the user experience.
  • Decoupling Microservices: Facilitating the communication between microservices in a loosely coupled manner.
  • Handling Workload Spikes: Buffering requests during peak traffic times, thus preventing system overload.

Sending Messages to SQS with Spring Boot


  • Spring Boot environment setup.
  • spring-cloud-starter-aws-messaging dependency added to your project.
  • An AWS account with access to SQS.
  • Configured AWS credentials, typically through the AWS CLI, IAM roles, or environment variables.
  • An existing SQS queue.

Implementing Message Sending

Step 1: Add Maven Dependency

Include the spring-cloud-starter-aws-messaging dependency in your pom.xml:


Replace YourDesiredVersion with the appropriate version for your Spring Boot application.

Step 2: Configure AWS Properties

Add your AWS region and credentials to or application.yml:

Replace with your AWS region and credentials.

Step 3: Create a Message Sending Service

Develop a service to send messages to an SQS queue:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

public class MessageSenderService {

    private final QueueMessagingTemplate queueMessagingTemplate;

    public MessageSenderService(QueueMessagingTemplate queueMessagingTemplate) {
        this.queueMessagingTemplate = queueMessagingTemplate;

    public void send(String queue, String message) {
        this.queueMessagingTemplate.convertAndSend(queue, message);

Step 4: Send a Message

Use the service to send messages to your SQS queue:

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

public class MessageController {

    private MessageSenderService messageSenderService;

    public void sendMessage(@RequestParam String queue, @RequestParam String message) {
        messageSenderService.send(queue, message);

Replace queue with the name of your SQS queue.

Step 5: Run Your Spring Boot Application

Start your Spring Boot application, and use the provided REST endpoint to send messages to your SQS queue.


Sending messages to Amazon SQS using Spring Boot is a straightforward process that allows for scalable and efficient asynchronous communication within distributed systems. This guide covers the essential steps to integrate SQS messaging into Spring Boot applications.

Utilizing SQS with Spring Boot enables the creation of robust, cloud-native applications, leveraging the strengths of both AWS and Spring Boot.
