项目结构

结构介绍

一、websocket服务注册到spring容器

@Configuration
public class WebSocketConfig {
    @Bean
    public ServerEndpointExporter serverEndpointExporter() {
        return new ServerEndpointExporter();
    }
}
二、开放服务节点
@Slf4j
@Component
@ServerEndpoint("/socket/server/{clientId}")
public class SocketServer {


    private Logger logger = LoggerFactory.getLogger(SocketServer.class);

    @OnOpen
    public void onOpen(@PathParam("clientId") String clientId, Session session) throws IOException {
        logger.info("客户端{}，上线。", clientId);
        session.getBasicRemote().sendText("欢迎上线。");
    }

    @OnClose
    public void onClose(@PathParam("clientId") String clientId) {
        logger.info("客户端{}，离线。", clientId);
    }

    @OnError
    public void one rror(@PathParam("clientId") String clientId, Throwable throwable) {
        logger.info("客户端{}，异常及异常原因：{}。", clientId, throwable);
    }


    @OnMessage
    public void handler(String receiveMessage, Session session) {
        //接收消息
        logger.info("客户端发送消息内容：{}。", receiveMessage);
        try {
            session.getBasicRemote().sendText("收到：" + receiveMessage);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}
