使用springboot整合websocket，启动时报错，示例代码：

@EnableWebSocket
@Configuration
public class WebSocketConfig implements WebSocketConfigurer {
    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry webSocketHandlerRegistry) {
        webSocketHandlerRegistry.addHandler(myWebSocketHandler(),"/ws").addInterceptors(new MyHandshakeInterceptor());
    }
    @Bean
    public WebSocketHandler myWebSocketHandler() {
        return new MyWebSocketHandler();
    }

    @Bean
    public ServletServerContainerFactoryBean createWebSocketContainer() {
        ServletServerContainerFactoryBean container = new ServletServerContainerFactoryBean();
        container.setMaxBinaryMessageBufferSize(8192); // 设置二进制消息缓冲区大小
        container.setMaxTextMessageBufferSize(8192); // 设置文本消息缓冲区大小
        container.setAsyncSendTimeout(5000l); // 设置异步发送超时时间（毫秒）
        // 其他配置项...

        return container;
    }
}

public class MyWebSocketHandler extends TextWebSocketHandler {

    @Override
    protected void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {
        // 处理接收到的文本消息
        String payload = message.getPayload();
        System.out.println("接收到消息：" + payload);

        // 发送响应消息
        session.sendMessage(new TextMessage("Hello, client!"));
    }

    @Override
    public void afterConnectionEstablished(WebSocketSession session) throws Exception {
        // WebSocket 连接建立时执行的操作
        System.out.println("WebSocket 连接已建立");
    }

    @Override
    public void afterConnectionClosed(WebSocketSession session, CloseStatus status) throws Exception {
        // WebSocket 连接关闭时执行的操作
        System.out.println("WebSocket 连接已关闭");
    }
}
@Configuration
@EnableWebSocketMessageBroker
public class WebSocketBrokerConfigurer implements WebSocketMessageBrokerConfigurer {

}
