Implementing WebSocket Communication in Spring Boot

WebSockets are a powerful technology for enabling real-time, two-way communication between clients and servers. They are widely used in applications such as chat systems, live updates, and online gaming. Spring Boot makes it easy to implement WebSocket communication by providing built-in support for WebSocket APIs. In this article, we will explore how to set up WebSocket communication in a Spring Boot application and create a simple chat application as an example.
