Creating the Websocket Server Spring will be able to handle the creation of the WebSocket connection, leaving the work of data management to us. Data is sent by WebSockets in small chunks called “Messages”.
Spring expects us to write code that can philippines mobile number example handle these messages. The easiest way to do this is to extend AbstractWebSocketHandler Spring's element.
Creating the WebSocket Handler The project you downloaded from Spring Initializr has a single class in a subdirectory src/main/Java called <class> <nom_votre_artefact>Application.java and in the same package you need to create a new class called <class> TwilioMediaStreamsHandler, with the following code: Java Copy the code // Note: package name will depend on your group and artifact name // Your IDE should be able to help you here package lol.
gilliard.websocketstranscription; import org.
springframework.web.socket.TextMessage; import org.springframework.web.socket.WebSocketSession; import org.springframework.web.socket.handler.AbstractWebSocketHandler; public class TwilioMediaStreamsHandler extends AbstractWebSocketHandler { @Override public void afterConnectionEstablished(WebSocketSession session) { System.out.println("New connection has been established"); } @Override public void handleTextMessage(WebSocketSession webSocketSession, TextMessage textMessage) { System.out.println("Message received, length is " + textMessage.getPayloadLength()); } @Override public void afterConnectionClosed(WebSocketSession session, CloseStatus status) { System.
out.println("Connection closed"); } } See the full code on GitHub When a new WebSocket client connects, the method afterConnectionEstablished is called. Then the method handleTextMessage is called repeatedly, each time there is a message.
When the connection is closed, the method afterConnectionClosed is called. Note that the element WebSocketSession is passed to all of these methods, allowing the application to track multiple WebSocket connections simultaneously.
