我需要添加jwt身份验证。我让jwt生成并验证类。我不知道如何在websocket中添加它。我认为spring必须在连接开始时检查jwt令牌
serverendpoint类

@Component
@ServerEndpoint(value = "/user", 
encoders = { MessageEncoder.class }, 
decoders = { MessageDecoder.class }
)
public class ChatEndpoint implements Serializable {

    @OnOpen
    public void OnOpen (Session session) throws IOException {

    }

    @OnMessage
    public void onMessage(Session session, Message message) throws IOException, EncodeException {

    }

    @OnClose
    public void onClose(Session session) throws IOException, EncodeException {

    }

    @OnError
    public void onError(Session session, Throwable throwable) {
        // Do error handling here
        System.out.println(throwable);
    }

    public static void broadcast(Message message) throws IOException {

    }
    private void sendMessage(Message message) throws IOException {

    }

}

初级班

@ServletComponentScan
@SpringBootApplication
public class WebsocketdemoApplication {

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(WebsocketdemoApplication.class);
        app.run(args);

    }

}

配置类

@Configuration
    public class WebSocketConfig {

        @Bean
        public ServerEndpointExporter endpointExporter(){
            return new ServerEndpointExporter();
        }
    }

我希望有人能帮助我。我想不起来了。每个人都在用跺脚，但我没有用，所以这很奇怪
