Spring ServletServerContainerFactoryBean Stomp mode is invalid

Hello, The tomcat web container websocket buffer size limit is 8kb, Use ServletServerContainerFactoryBean can be adjusted to 64kb. But it does not support Stomp. I have searched various materials to modify the limit, but all failed. Please give me some guidance, thank you!

@Configuration
public class MyServerContainerConfigurer{
      @Bean
      public ServletServerContainerFactoryBean createWebSocketContainer() {
            ServletServerContainerFactoryBean container = new ServletServerContainerFactoryBean();
            container.setMaxTextMessageBufferSize(64*1024);
            container.setMaxBinaryMessageBufferSize(64*1024);
            return container;
      }
}

Effective in normal mode, as shown in the following example.

@Configuration
@EnableWebSocket
public class MyWebSocketConfigurer implements WebSocketConfigurer {

    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
        registry.addHandler(new TextWebSocketHandler(),"/endpoint").setAllowedOrigins("*");
    }
}

It is invalid in Stomp mode, Example of Stomp.

@Configuration
@EnableWebSocketMessageBroker
public class MyWebSocketMessageBrokerConfigurer implements WebSocketMessageBrokerConfigurer {


    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/portfolio").setAllowedOrigins("*");
    }


    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.setPathMatcher(new AntPathMatcher("."));
        config.setApplicationDestinationPrefixes("/app");
        config.enableSimpleBroker("/topic", "/queue");
    }


    @Override
    public void configureWebSocketTransport(WebSocketTransportRegistration webSocketTransportRegistration) {
        webSocketTransportRegistration
                .setMessageSizeLimit(1024 * 1024)
                .setSendBufferSizeLimit(1024 * 1024 );

    }


}

@liyiorg did you find anything more? The above should work. I am going to close this here, as we now also have #31616, which is on the same issue. Please, feel free to comment there while we investigate, or here if needed.
