Question

我有通过网络套接字进行交互的服务器和客户端应用程序。

有关客户端应用配置的问题我有以下配置：

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

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/ws").withSockJS()
                .setStreamBytesLimit(Integer.MAX_VALUE)
                .setHttpMessageCacheSize(Integer.MAX_VALUE);
    }

    @Bean
    public WebSocketStompClient getClient() {
        logger.debug("getClient invoked");
        List<Transport> transports = new ArrayList<>();
        transports.add(new WebSocketTransport(new StandardWebSocketClient()));
        WebSocketClient webSocketClient = new SockJsClient(transports);
        WebSocketStompClient stompClient = new WebSocketStompClient(webSocketClient);
        stompClient.setMessageConverter(new MappingJackson2MessageConverter());
        stompClient.setInboundMessageSizeLimit(Integer.MAX_VALUE);
        return stompClient;
    }

    @Bean
    public ServletServerContainerFactoryBean createServletServerContainerFactoryBean() {
        ServletServerContainerFactoryBean container = new ServletServerContainerFactoryBean();
        container.setMaxTextMessageBufferSize(Integer.MAX_VALUE / 1000);
        container.setMaxBinaryMessageBufferSize(Integer.MAX_VALUE / 1000);
        logger.info("Websocket factory returned");
        return container;
    }

但在调试中我看到调用构造函数时：org.springframework.web.socket.config.annotation.WebMvcStompEndpointRegistry#WebMvcStompEndpointRegistry

if (transportRegistration.getMessageSizeLimit() != null) {
            this.stompHandler.setMessageSizeLimit(transportRegistration.getMessageSizeLimit());
        }

这种情况是错误的。

我也试着写：

@Bean
    public WebSocketTransportRegistration getRegistration(WebSocketTransportRegistration registration) {
        logger.debug("getRegistration invoked");
        registration.setSendBufferSizeLimit(Integer.MAX_VALUE);
        registration.setMessageSizeLimit(Integer.MAX_VALUE);
        registration.setSendTimeLimit(Integer.MAX_VALUE);
        registration.setSendTimeLimit(60 * 1000);
        return registration;
    }

但它导致以下错误：
