How do I connect to spring boot websocket?

springboot config

    override fun registerStompEndpoints(registry: StompEndpointRegistry) {
        super.registerStompEndpoints(registry)
        registry.addEndpoint("/idea-chat")
            .setAllowedOrigins("*")
            .setHandshakeHandler(principalHandshakeHandle)
            .addInterceptors(jwtVaildInterceptor)
    }

    override fun configureMessageBroker(registry: MessageBrokerRegistry) {
        registry.enableSimpleBroker("/queue", "/topic")
        registry.setUserDestinationPrefix("/user")
        super.configureMessageBroker(registry)
    }

    private  var tokenField = JTextField()

    @OptIn(DelicateCoroutinesApi::class)
    private fun socketConnect() {
        GlobalScope.launch {
            val stompClient = StompClient(KtorWebSocketClient())
            try{
                val session = stompClient.connect("ws://192.168.199.86/idea-chat?token=${tokenField.text}")
                val subscribeText = session.subscribeText("/room/闲聊吹水")
                launch {
                    subscribeText.collect {msg ->
                        println("msg=:$msg")
                    }
                }
            }catch (e: StompConnectionException) {
                println(":$e  ")
            }
        }
    }

I’m a novice. It’s boring. I can’t connect it with anything

my code repository https://github.com/mdddj/json_to_dart_pro/blob/ab5e947ea6612358ac84b2a15449f8fe4cbb1ccd/src/main/kotlin/windown/ChatWindow.kt#L49

Thank you for your help. I found a solution to the problem. Deleting the @ EnableWebSocketSecurity annotation in Springboot3.0 will solve the problem

Glad that you found the problem!
