spring-websocket

问题 I am new to Spring boot websocket and messaging semantics. Currently i am able to send private messages using the below code. String queueName = "/user/" + username + "/queue/wishes"; simpMessagingTemplate.convertAndSend(queueName, message); When trying to use convertAndSendToUser I am not getting any error but the message is not getting sent.

问题 I managed to create a WebSocketHandler using the Spring 5 Reactive WebSocket support (Chapter 23.2.4). Receiving and sending all works fine. However, I can not figure out how to detect a client disconnect. When debugging a client disconnect it somewhere stops at the server side in the HttpServerWSOperations class ( netty.http.server package), where it does detect a CloseWebSocketFrame . Any suggestions how to deal with client disconnects? 回答1: I implemented a close event handler in a reactive
