        config.enableSimpleBroker("/topic"); // 配置消息代理前缀
        config.setApplicationDestinationPrefixes("/app"); // 配置应用程序前缀
    }

    // 注册WebSocket端点
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/websocket").withSockJS(); // 注册WebSocket端点
    }
}

@Component
public class MyWebSocketHandler extends TextWebSocketHandler {
    @Override
    protected void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {
        // 处理接收到的WebSocket消息
        String payload = message.getPayload();
        // 获取Cookie
        List<String> cookies = session.getHandshakeHeaders().get("Cookie");
        // 处理Cookie
        // ...
