Jetty websocket client connect to Stomp.js topic channel
websocket,client,jetty,spring-websocket
In general, plain websocket clients (as the one provided by Jetty) support the websocket standard. STOMP is a protocol that sits on top of that transport. Here, you'd need to implement your own STOMP client or interface an existing one with the websocket client you're using. Spring 4.2 (to be...
What are the pitfalls of using Websockets in place of RESTful HTTP?
rest,http,websocket,client-server,spring-websocket
With RESTful HTTP you have a stateless request/response system where the client sends request and server returns the response. With webSockets you have a stateful (or potentially stateful) message passing system where messages can be sent either way and sending any given message is lower overhead than with a RESTful...
How do I decorate a websocket handler within PerConnectionWebSocketHandler?
java,spring,java-ee,spring-websocket
WebSocketHandlers can be nested within each other: @Bean public WebSocketHandler myHandler() { return new PerConnectionWebSocketHandler(MyHandler.class)); } @Bean public WebSocketHandler myHandlerDecorator() { return new ExceptionWebSocketHandlerDecorator(myHandler()); } This is for case, when you are going to use BeanFactory to autowire your target MyHandler or via simple way: @Bean public WebSocketHandler myHandlerDecorator() {...
spring-messaging xml config with stomp and spring-sessions
spring-websocket,spring-messaging,spring-session
The Spring Session WebSocket contains the config just only for the Java & Annotation variant. And according to the Spring Session Docs the AbstractSessionWebSocketMessageBrokerConfigurer does the stuff for seamless integration between Spring Session and Spring WebSockets. However there we can see some paragraph, what it does: To hook in the...
not updated template view -> it needs mous scroll, or clear input
angularjs,angularjs-scope,angularjs-ng-repeat,spring-websocket
You probably need to use scope.$apply to have it take effect. afaics sock.js is not made for angular, so you need to let angular know something has changed on the scope. You do this using scope.$apply. $scope.notifyMessage = function(message) { $scope.$apply(function(){ $scope.initiator = true; $scope.messages.push(message) }); }; ...

Integrate spring-reactor into existing Spring Framework 4 STOMP Over WebSocket application
java,spring,spring-mvc,spring-websocket,spring-messaging
Actually the RingBufferAsyncTaskExecutor isn't ThreadPoolTaskExecutor, so you can't use it that way. You can simply override clientInbound(Outbound)Channel beans from your AbstractWebSocketMessageBrokerConfigurer impl and just use @EnableWebSocketMessageBroker: @Configuration @EnableWebSocketMessageBroker @EnableReactor public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer { @autowired Environment reactorEnv; @Override public void registerStompEndpoints(StompEndpointRegistry registry) {...
SpringFramework schema/integration/websocket namespace does not exist
spring,spring-integration,spring-websocket
We'll take a look why it isn't there. Because WebSockets support has been added since Spring Integration 4.1. Anyway the IDE should determine XSD from the spring-integration-websocket dependency. The XSD is on location \org\springframework\integration\websocket\config\ within that jar....
Disallow broadcast in convertAndSendToUser method in SimpMessagingTemplate
If we take a look to the SendToMethodReturnValueHandler source code, we'll see: if (broadcast) { this.messagingTemplate.convertAndSendToUser(user, destination, returnValue); } else { this.messagingTemplate.convertAndSendToUser(user, destination, returnValue, createHeaders(sessionId)); } So, what you need for your use-case just use that overloaded convertAndSendToUser and provide a Map with `sessionId: messagingTemplate.convertAndSendToUser(user, destination, payload, Collections.singletonMap(SimpMessageHeaderAccessor.SESSION_ID_HEADER,...
Spring Websocket Reply To User Message Flow
The @SendToUser annotation defines that the return value of the method should be send to a user destination prefixed with /user/{username} where the user name is extracted from the headers of the input message being handled (current user). In Spring 4.2 you can use placeholders in @SendTo (only destination variable...
Spring Websocket Stomp handle CONNECT frame
If we take a look to the StompSubProtocolHandler code, we'll see this: try { SimpAttributesContextHolder.setAttributesFromMessage(message); if (this.eventPublisher != null) { if (StompCommand.CONNECT.equals(headerAccessor.getCommand())) { publishEvent(new SessionConnectEvent(this, message, user)); } ........ outputChannel.send(message); } So, the CONNECT frame not only emitted as a SessionConnectEvent, but is sent to the clientInboundChannel as well. So,...

Spring WebSocket - sequential delivery of messages on clientOutboundChannel (per Queue)
spring,websocket,spring-websocket
[EDITED] Thanks, I see now. Indeed at present there is no way to ensure messages from the external broker are delivered to a client in the exact same order and that messages from a client will be sent to the external broker in the exact same order. We could assign...
Confused about how to make stomp calls with Spring-websockets
java,spring,websocket,stomp,spring-websocket
So it seems that there must be some special case where this works: var socket = new WebSocket("/spring-websocket-portfolio/portfolio"); I ended up making the connection by using the path: ws://localhost:8080/MyWebAppName/portfolio Portfolio is the name of my stomp endpoint. I guess in this context of the documentation the hostname and port doesn't...
Spring boot websocket 1.2.1.RELEASE - IllegalArgumentException in bean 'subProtocolWebSocketHandler' : No handlers
java,spring,spring-boot,spring-websocket
The root of the problem is that you haven't configured any endpoints in registerStompEndpoints. An application that's trying to use STOMP, but has not configured any STOMP endpoints, won't work correctly. When you're using Spring Boot 1.1.9.RELEASE you'll have some Spring Framework 4.0.x jars on your classpath. Spring Framework 4.0.x's...
Sending a BinaryMessage from java WebSocketStompClient

Spring 4 AbstractWebSocketMessageBrokerConfigurer With SockJS Not Negotiating Transport Properly
spring,websocket,stomp,sockjs,spring-websocket
Since SockJS was producing a weird string error when attempting the WebSocket connection, then fell back to xhr_streaming, I decided to load up the non-minified version of the .js file and debug it in Firebug to see what was going on. Turns out, SockJS does not like relative URLs, which...

How to correctly implement a spring-websocket java client
If it is interesting Spring Integration provides an implementation for the WebSocketClient. And yes, internally it uses ConnectionManagerSupport. Here is a test-case which demonstrate how to configure it from @Configuration. But I think you should try with out-of-the-box WebSocketHandler implementation - SubProtocolWebSocketHandler, and StompSubProtocolHandler....

Spring integration connecting inbound HTTP gateway with outbound Websocket gateaway
spring-integration,spring-websocket
Unfortunately, your question isn't clear. If your WebSocket stuff is based on the Spring Integration WEbSocket adapters, you have ServerWebSocketContainer which has getSessions() to return Map<String, WebSocketSession> of connected client sessions. Hence you can expose to end-users via REST service. When the client select one session and send an HTTP...
Spring WebSocket - messages lost after being sent by controller
After intensive debugging of my application and especially the Spring code that handles I found the reason for that behavior. The issue was neither the controller nor the Spring internal processes, it was the class that I use for Principal objects during Spring Security authentication. It stores the last heartbeat...

Disconnect client session from Spring websocket stomp server
spring,spring-boot,stomp,spring-websocket
As far as I know the API doesn't provide what you are looking for, on server-side you can only detect disconnect events. If you want to disconnect a certain client I think you must go for a litte workaround, e.g. this one: Write a client-side javascript function that is able...
Can I use the spring context in javax websocket?
spring,spring-security,websocket,spring-websocket
You don't provide enough details to be sure but using the WebApplicationContextUtils class could give you access to your Spring context. You can use beans defined in your context but you can't use all of Spring's capabilities since you are outside of the Spring container. If you want full Spring...
Spring security/Spring session/Web sockets
spring-security,spring-websocket,spring-messaging,spring-session
Coworker of the accursed here. Our configuration is largely correct but our issue stemmed from a bit of a misunderstanding around the security context and its availability from the websocket side of things. Comments gathered from various sub-issues of https://jira.spring.io/browse/SEC-2179 led us to grabbing the logged in user principal from...
WebSocketStompClient won't connect to SockJS endpoint
The following configuration works: RequestUpgradeStrategy upgradeStrategy = new TomcatRequestUpgradeStrategy(); registry.addEndpoint("/hello") .withSockJS(); registry.addEndpoint("/hello") .setHandshakeHandler(new DefaultHandshakeHandler(upgradeStrategy)) .setAllowedOrigins("*"); Not sure if this is by design (i.e. two endpoints with the same path)? A better solution based on Brian-Clozel's feedback is to use the java SockJsClient as a transport when configuring the WebSocketStompClient: List<Transport>...
How WebSocket server handles multiple incoming connection requests?
http,websocket,spring-websocket
The relatively straightforward thing you seem to be missing here is that each connection to a server (in particular to your HTTP server here) creates it's own socket and then runs on that socket. What happens on one socket is completely independent of what happens on any other socket that...
Spring-Integration websocket exception “No adapter for handler SockJsHttpRequestHandler”

Certainly do-able. You'll need to change some things up. It's all described here: Using Queue Browsers to Implement Durable Topic Subscriptions But i'll give you a quick rundown. Some important changes to your messaging structure: Subscribe your websocket consumers to "/queue/"s instead of topics and setup queue browsing. Send messages...

Replying multiple times over web-socket without spring authentication
Why don't you use a separate topic for each client? Client generates a session id. var sessionId = Math.random().toString(36).substring(7); Client subscribes to /topic/testwsresponse/{sessionId}, then sends a message to '/app/testws/{sessionId}'. In your controller you use @MessageMapping(value="/testws/{sessionId}") and remove @SendToUser. You can use @DestinationVariable to access sessionId in your method. The controller...

How to get properly all queue messages from RabbitMQ in Spring?
