Thankyou for this. Best video on spring websocket so far.

[@PrashantPujari-q9e]

Can you please tell me on how to switch to wss from ws using SSL. (I am using spring websocket without stomp & sockjs)

[@Code.Wizzard]

Thanks for your kind comments. Switching to SSL is straight forward
For dev environment you can first create a self signed certificate using the below command. For production, it's recommended to obtain a certificate from a trusted CA.
keytool -genkeypair -alias websocket -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore websocket.p12 -validity 3650
Add the below to application.properties
server.ssl.key-store=file:/websocket.p12
server.ssl.key-store-password=
server.ssl.keyStoreType=PKCS12
server.ssl.keyAlias=websocket
server.ssl.enabled=true
After that you can access the websocket using url starting with wss://

Thanks for your kind feedback

[@OleksandrProkopenko_ua]

but i have a question: so how we can test 2nd version of your example with postman? Is it absolutly impossible? or is it just hard and inconveniently?

[@Code.Wizzard]

Since the second one uses STOMP protocol on top of Websocket, I think it might not work since there are no options in postman to enable that. Will try to explore more.

[@OleksandrProkopenko_ua]

@@Code.Wizzard so it is a case to create simple html page to test your backend app, right?
Or maybe is there an ability to write integration tests for this purpose?

[@Code.Wizzard]

@@OleksandrProkopenko_ua correct, either can test it from a UI or write integration test using WebSocketStompClient
