Introduction
The spring-boot-starter-stomp dependency plays a pivotal role in enabling STOMP (Simple Text Oriented Messaging Protocol) over WebSocket in Spring Boot applications. STOMP is a messaging protocol that simplifies the exchange of information in real-time applications. By integrating this dependency, Spring Boot provides a seamless way to build WebSocket-based messaging systems with efficient communication between clients and servers.
Features of spring-boot-starter-stomp
1. Simplifies WebSocket Messaging
The spring-boot-starter-stomp dependency abstracts the complexity of working with raw WebSockets by introducing the STOMP protocol, which allows for easy subscription and broadcasting of messages to multiple clients.
- It supports publish-subscribe messaging.
- It enables broadcasting messages to multiple subscribers efficiently.
2. Built-in Support for Message Brokers
The dependency integrates with message brokers such as RabbitMQ or ActiveMQ to handle messaging at scale. Alternatively, it can also work with an in-memory broker for simpler use cases.
Setting Up spring-boot-starter-stomp
Adding the Dependency
To include the STOMP starter in your Spring Boot application, add the following dependency to your pom.xml:

spring-boot-starter-stompis bundled withinspring-boot-starter-websocket.
Configuring WebSocket with STOMP
Here’s a basic example to configure STOMP messaging over WebSocket:
Practical Example: Real-Time Chat Application
1. Controller for Messaging
Create a controller to handle messages sent from clients.
2. Front-End Integration
Integrate the WebSocket endpoint into the front-end using a STOMP client. For example:
Benefits of spring-boot-starter-stomp
- Ease of Use: Simplifies the development of real-time applications by leveraging STOMP over WebSocket.
- Scalability: Supports external brokers for handling high-throughput messaging.
- Protocol Flexibility: Adopts a standard protocol (STOMP) for compatibility with various clients and servers.
- SockJS Fallback: Ensures reliable communication even in browsers that don’t fully support WebSocket.
Conclusion
The spring-boot-starter-stomp dependency is essential for implementing real-time, WebSocket-based messaging systems in Spring Boot. It bridges the gap between WebSocket and traditional messaging paradigms by introducing STOMP, a lightweight protocol that supports publish-subscribe communication. By leveraging this dependency, developers can build scalable, efficient, and robust real-time applications.
