WebSocket support

WebSocket is a protocol that allows full-duplex, two-way communication between a server and a client. While establishing the connection, it uses HTTP for the initial handshake. Once done, it will request a protocol upgrade. The Spring WebFlux framework supports reactive WebSocket communication between a client and server based on  the Java WebSocket API. Defining WebSocket is a two-step process as follows:

• Define the handler to manage the WebSocket request
• Define mapping to access  the specific handler

In WebFlux, the WebSockets are handled by implementing the WebSocketHandler interface. It has one method calledhandle(). It is provided with the object of WebSocketSession every time a connection is established to the handler. ...
