The following example https://github.com/graphql-java/graphql-java-subscription-example which use's graphql-java for subscriptions over a websocket.
How can the same idea be done within the spring version? GraphQLSubscriptionResolver needs to return a publisher but I am unable to work out how this can then be used with a web socket.
The example above seems fine within a none spring version.
A good friend of mine has made an example in his github repository. The code is not the nicest (because it was for our own personal needs) but it is a nice example
Have fun
