Using WebSocket to build an interactive web application.

What is Websocket?

WebSocket is a computer communications protocol, providing full-duplex communication channels over a single TCP connection.

This is the main reasion which websocket is preferred over the HTTP protocol when building a chat-like communication service that operates at high frequencies with low latency.

Configuring WebSocket

• @EnableWebSocketMessageBroker annotation is used to enable our WebSocket server.
• WebSocketMessageBrokerConfigurer interface is used to provide implementation for some of its methods to configure the websocket connection.
• registerStompEndpoints method is used to register a websocket endpoint that the clients will use to connect to the server.
• configureMessageBroker method is used to configure our message broker which will be used to route messages from one client to another.
