问题 I am using Spring to setup Stomp server endpoints (extending AbstractWebSocketMessageBrokerConfigurer) @Override public void configureMessageBroker(MessageBrokerRegistry config) { config.enableStompBrokerRelay("/topic","/queue") .setRelayHost(<rmqhost>); } @Override public void registerStompEndpoints(StompEndpointRegistry registry) { registry.addEndpoint("/myapp/websockets").setAllowedOrigins("*"); } The objective is that I can have multiple servers, and a client will connect to any one of

问题 I try to set handshake handler through xml config: <bean id="customHandler" class="app.wsock.CustomHandler"/> <websocket:message-broker> <websocket:stomp-endpoint path="/foo"> <websocket:handshake-handler ref="customHandler"/> <websocket:sockjs/> </websocket:stomp-endpoint> <websocket:stomp-broker-relay prefix="/topic,/queue" /> </websocket:message-broker> but on connect also using DefaultHandshakeHandler. What I'm doing wrong? 回答1: This is a bug (see SPR-11568). You'll need to update your

问题 My SockJs client in webpage, sends message with a frame size of 16K. The message size limit is what determines the max size of the file that I can transfer. Below is what I found in the doc. /** * Configure the maximum size for an incoming sub-protocol message. * For example a STOMP message may be received as multiple WebSocket messages * or multiple HTTP POST requests when SockJS fallback options are in use. * * <p>In theory a WebSocket message can be almost unlimited in size. * In practice

问题 I am configuring currently my Spring Websocket using the class public class WebSocketConfig extends WebSocketMessageBrokerConfigurationSupport now I came across the advice Spring STOMP Websockets: any way to enable permessage-deflate on server side? that makes use of public class SampleJettyWebSocketsApplication implements WebSocketConfigurer and overrides @Override public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) and offers @Bean public DefaultHandshakeHandler

问题 From WebSocket Endpoint I try to call Singleton Service. But I an unable to use Request or Session scope from WebSocket. (@Scope( value = "request", proxyMode = ScopedProxyMode.TARGET_CLASS)) I get Scope 'request' is not active for the current thread; For 'request' or 'session' scope on any 'ScopedProxyMode'. Thanks for the help! 回答1: For web sockets there are no request/response so the request scope is invalid. They introduced new scope called websocket in Spring 4.1. @Scope(name =

问题 I'm using a very thin implementation of Spring's WebSockets. WebSocketSession has the method getPrincipal(), but how can I set it from within a HandshakeInterceptor? The method I would like to put the Principal in is: public boolean beforeHandshake(final ServerHttpRequest request, final ServerHttpResponse response, final WebSocketHandler wsHandler, final Map<String, Object> attributes) throws Exception { Principal = getPrincipal(); // Now where to set the principal so it is available in

问题 I am using SimpUserRegistry to get online user-count (with getUserCount() ). And it is working good on my local machines but not on AWS EC2 instances (tried with Amazon Linux and Ubuntu) with just elastic IP and no load balancer. The problem on EC2 is that some users, when connected, are never added to the registry and thus I get wrong results. I have session listeners, for SessionConnectedEvent and SessionDisconnectEvent , where I use the SimpUserRegistry (autowired) to get the user presence

问题 In my Spring boot application i use also websockets. Everything works fine, as expected in production. Now i started to create UnitTests with Spring-Boot-Test. Every time i start a @SpringBootTest , i get following exception (shortened): java.lang.IllegalStateException: Failed to load ApplicationContext Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'createWebSocketContainer' defined in class path resource [com/package/spring/ws

问题 I'm having trouble with SockJs and CORS. I use spring. I set up the WebMvcConfigured as follows: @Bean public WebMvcConfigurer corsConfigurer() { return new WebMvcConfigurer() { @Override public void addCorsMappings(CorsRegistry registry) { registry .addMapping("/**") .allowedOrigins("http://localhost:3000") .allowCredentials(true); ; } }; } and WebSocketConfig as follows: @Override public void configureMessageBroker(MessageBrokerRegistry config) { config.enableSimpleBroker("/topic"); config
