问题 Trying to use Spring 4 WebSocket with STOMP over socket using sockjs. And i faced a problem. My configuration: websocket.xml - part of spring context <websocket:message-broker application-destination-prefix="/app"> <websocket:stomp-endpoint path="/ws"> <websocket:sockjs/> </websocket:stomp-endpoint> <websocket:simple-broker prefix="/topic"/> </websocket:message-broker> Controller code: @MessageMapping("/ws") @SendTo("/topic/ws") public AjaxResponse hello() throws Exception { AjaxResponse

问题 I can either use websocket that configure with WebSocketConfigurer or use @Scheduled() to schedule task without any problem.

问题 My server side config is here: <websocket:message-broker application-destination-prefix="/chat"> <websocket:stomp-endpoint path="/connect"> <websocket:sockjs/> </websocket:stomp-endpoint> <websocket:simple-broker prefix="/broadcast/"/> </websocket:message-broker> Client side code: var stompClient = null; var socket = new SockJS('/connect'); stompClient = Stomp.over(socket); stompClient.connect('', '', function (frame) { console.log(frame); // Inside frame object queue-suffix not sended var

问题 I initialize my SockJs URL as var protocols = ['xhr-polling', 'xdr-polling', 'xdr-streaming', 'xhr-streaming']; var options = {protocols_whitelist: protocols, debug: true,server:tets}; _ws = new SockJS(url, null, options); I want to send out a request parameter , for example somesite/sockjs/info?someparam=tets" Is it possible? Documentation of SockJs refers that options is map which can have key value but i am not sure what key to use here. I verified URL at server which SockJs sends over and
