STOMP or XMPP - Over websocket

由 大憨熊 提交于 2019-12-12 08:21:30

Then I came across STOMP (as a sub-protocol for websockets)and as there is direct support for STOMP in spring it was bit easy to achieve what I was supposed to do. But my doubt is as far as my understanding STOMP and XMPP are similar protocols

Is there a way I can have this behaviour in SimpMessagingTemplate . 回答1: If we take a look to the SendToMethodReturnValueHandler source code, we'll see: if (broadcast) { this

Spring boot application with websocket client only

由 心不动则不痛 提交于 2019-12-12 04:21:07

How can I switch off Jetty server part, so it won't get activated at startup and does not listen on a port? 回答1: I'm sorry for the delay in having your question answered. I also had difficulty finding the answer, so I created a repository in Github with a simple solution, its here: https://github.com/GleidsonSilva/springboot-ws-client I hope it is still useful to someone! :)

问题 I am using spring-WebSocket for receiving records via WebSocket channel. After receiving them I send it to an external broker like activeMQ.

Error handling while using STOMP simple broker

问题 I am creating simple STOMP broker using @EnableWebSocketMessageBroker . When RuntimeException happens in @MessageMapping method I would like to receive STOMP ERROR frame, but it doesn't work like that by default.
