This article explains how to implement real-time notifications in Spring Boot applications using WebSockets. Real-time notifications are crucial for enhancing user engagement and responsiveness in modern applications.
The implementation involves setting up a Spring Boot application with necessary dependencies (Spring Web and WebSocket), configuring WebSocket connections, and potentially adding Spring Boot DevTools for easier development. The guide focuses on using Maven for dependency management and showcases code snippets for configuring the WebSocket setup.
Real-time notifications are a critical feature for many modern applications, enhancing user engagement and improving responsiveness. Spring Boot, with its powerful ecosystem, makes implementing real-time notifications straightforward and efficient.
In this blog, we’ll explore how to build a real-time notification system using Spring Boot and WebSocket.
Real-time notifications allow applications to push updates to users instantly. This eliminates the need for users to refresh the page or make repeated requests to check for updates.
Typical use cases include:
Start by creating a Spring Boot application with the following dependencies:
Add the dependencies to your pom.xml (for Maven):
<dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-websocket</artifactId> </dependency></dependencies>
Create a WebSocket configuration class to establish the connection.
import org.springframework.context.annotation.Configuration;import org.springframework.web.socket.config.annotation.EnableWebSocket;import org.springframework.web.socket.config.annotation.WebSocketConfigurer;import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;@Configuration@EnableWebSocketpublic class WebSocketConfig implements WebSocketConfigurer { @Override public void registerWebSocketHandlers(WebSocketHandlerRegistry…Skip the extension — just come straight here.
