spring-websocket

I want to send message to user when he connects to spring websocket, I've @Configuration @EnableWebSocketMessageBroker public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer { @Autowired private GenervicSerice<User> userService; @Autowired private SimpMessagingTemplate template; private CurrentUser currnetUser; @Override public void registerStompEndpoints(StompEndpointRegistry stompEndpointRegistry) { // TODO Auto-generated method stub stompEndpointRegistry.addEndpoint("/ws").withSockJS(); } @Override public void configureMessageBroker(MessageBrokerRegistry config) {

Using SockJS java client, I am trying to connect to Spring sockjs server and is getting error 1009 for messages (without headers) of ~20Kb. Javascript library works fine. Transport closed with CloseStatus[code=1009, reason=The decoded text message was too big for the output buffer and the endpoint does not support partial messages] in WebSocketClientSockJsSession [id='9fa30eb453e14a8c8612e1064640646a, url=ws://127.0.0.1:8083/user] I have couple of config classes on server (I do not know at the moment if I am configuring these things more times than necessary): @Configuration @EnableWebSocket

I have added custom token based authentication for my spring-web app and extending the same for spring websocket as shown below public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer { @Override public void configureMessageBroker(MessageBrokerRegistry config) { config.enableSimpleBroker("/topic", "/queue"); config.setApplicationDestinationPrefixes("/app"); config.setUserDestinationPrefix("/user"); } @Override public void registerStompEndpoints(StompEndpointRegistry registry) { registry.addEndpoint("/gs-guide-websocket").setAllowedOrigins("*").withSockJS(); } @Override

I've a web application using the spring(4.2.x) artifacts spring-webmvc, spring-messaging, spring-websocket I've the below @Enable* annotations in my spring config java class @EnableWebMvc @EnableWebSocketMessageBroker @EnableAsync @EnableMBeanExport WebSocket is used for broadcasting messages to browser clients. And there are few async methods annotated with @Async The application was working fine with spring version 4.2.0.RC3. But when I changed it to the GA release 4.2.0.RELEASE, I get the below exception on startup. If I remove @EnableAsync it works fine, but I need the async functionality.

In our current application, we use Spring Websockets over STOMP. We are looking to scale horizontally. Are there any best practices on how we should handle websocket traffic over multiple tomcat instances and how can we maintain session info across multiple nodes.Is there a working sample that one can refer to? Thanh Nguyen Van Your requirement can be divided into 2 sub tasks: Maintain session info across multiple nodes: You can try Spring Sessions clustering backed by Redis (see: HttpSession with Redis ). This very very simple and already has support for Spring Websockets (see: Spring Session
