WebSockets & Real-Time Systems with Spring · Lesson

WebSocket Endpoint Configuration

Configure WebSocket endpoints in Spring, defining paths and handling initial connections.

What are WebSocket Endpoints?

Imagine a special doorway for real-time communication. In Spring, this doorway is called a WebSocket endpoint.

It's a specific URL path, like /ws or /chat, that your clients (e.g., web browsers) connect to for WebSocket communication. Without it, your server wouldn't know where to listen for real-time requests!

Spring Boot App Entry Point

Before configuring WebSockets, let's recall our Spring Boot application's main entry point. This is where your application starts running.

The @SpringBootApplication annotation simplifies setup by bundling common Spring annotations.

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class MyApplication {
  public static void main(String[] args) {
    SpringApplication.run(MyApplication.class, args);
  }
}
