springboot+websocket-1 最简化 4个回调函数

最简单的ws连接，暂时只用来接收client的数据，并在server打印。

配置文件

@Configuration
public class WebsocketConfig {
    @Bean
    public ServerEndpointExporter serverEndpointExporter() {
        return new ServerEndpointExporter();
    }
}

回调函数

@Component
@ServerEndpoint("/cmd/ws/{shopId}")
@Slf4j
public class CmdWebsocket {

    private Session session;

    @OnOpen
    public void onOpen(@PathParam(value = "shopId") String shopId, Session session) {
        this.session = session;
        log.debug("cmd.ws on OPEN: {}", shopId);
    }

    @OnClose
    public void onClose(@PathParam(value = "shopId") String shopId) {
        log.debug("cmd.ws on CLOSE: {}", shopId);
    }

    @OnError
    public void onError(@PathParam(value = "shopId") String shopId, Throwable error) {
        log.error("cmd.ws on ERROR: shop_id={}\nerr_msg={}\nstack_trace={}", shopId, error.getMessage(), error.getStackTrace());
    }

    @OnMessage
    public void onMessage(@PathParam(value = "shopId") String shopId, String message) {
        log.debug("cmd.ws on MESSAGE: shop_id={}\nmessage={}", shopId, message);
    }
}
