Spring Boot Stomp WebSocket

Question

I seem to be running into an issue bumping up against the 8k size limit that embedded tomcat has for stomp websocket messages.

When sending a message from server to client I am getting the following error. Based on the documentation I've read, it seems that tomcat has a limit of 8k for messages going across websockets, but ive also read that Stomp can send partial messages and have the client reassemble them which doesnt seem to be happening.

The message is never getting to the client side handler so I'm pretty confident the issue is in my WebSocketConfig but it seems no matter what parameter I've tried I can not get over the A) size limit of 8k messages and/or B) if its over the buffer limit, send it in partial message chunks.

Both sides have the following error code

[code=1009, reason=The decoded text message was too big for the output buffer and the endpoint does not support partial messages]

I pretty sure I'm missing something easy but can't seem to put my finger on it. Any extra eyes would be appreciated. Thanks!

Server Side Stomp WebSocket Config

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {


private static final Logger logger = LoggerFactory.getLogger(WebSocketConfig.class);



@Override
public void configureMessageBroker(MessageBrokerRegistry config) {
    config.enableSimpleBroker(
            "/resp",
            "/not", 
            "/sub"
        );
    config.setApplicationDestinationPrefixes("/admin");
    config.setUserDestinationPrefix("/admin");

}


@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
    RequestUpgradeStrategy upgradeStrategy = new TomcatRequestUpgradeStrategy();
    registry.addEndpoint("/cmd",
                        "/connect")
                        .setHandshakeHandler(new DefaultHandshakeHandler(upgradeStrategy))
                        .setAllowedOrigins("*")
                        .withSockJS();




}

@Override
public boolean configureMessageConverters(List<MessageConverter> messageConverters) {
    messageConverters.add(new org.springframework.messaging.converter.StringMessageConverter());
    return true;
}


@Override
public void configureWebSocketTransport(WebSocketTransportRegistration registration) {
    registration.setSendTimeLimit(15*1000);
    registration.setMessageSizeLimit(16*1024);
    registration.setSendBufferSizeLimit(16*1024);


}

@Bean
public ServletServerContainerFactoryBean createServletServerContainerFactoryBean() {
    ServletServerContainerFactoryBean container = new ServletServerContainerFactoryBean();

    container.setMaxTextMessageBufferSize(16*1024);
    container.setMaxBinaryMessageBufferSize(16*1024);
    logger.info("Websocket factory returned");
    ContainerProvider.getWebSocketContainer().setDefaultMaxTextMessageBufferSize(20*1024);
    return container;
}

}

Answer 1

You can change max text buffer size according to your needs:

WebSocketContainer container = ContainerProvider.getWebSocketContainer();
container.setDefaultMaxTextMessageBufferSize(MAX_TEXT_MESSAGE_BUFFER_SIZE);
WebSocketClient wsClient = new StandardWebSocketClient(container);
