Spring boot graphql-java and subscriptions

Question

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

This example uses the graphql-java-annotations library, but the spring and subscription parts should be the same as if it used graphql-java – Guy Smorodinsky Mar 07 '18 at 20:35

Here's a port of the graphql-java example using GraphQL-SPQR with Spring Boot. I'll soon merge it into the GraphQL-SPQR samples project.

Same as with the other answer, while it uses GraphQL-SPQR to generate the schema, the Spring and websockets bit is the same as you'd have with graphql-java directly.

There's now a new and somewhat more realistic example using GraphQL SPQR Spring Boot Starter. It publishes updates when a relevant mutation runs.

I just published a workshop in which you can learn how to implement the subscription operations.

Let me know If you have any doubt

I hope you find it useful! Thanks

It's better to include the gist here, and the link as an extra. – Til Mar 03 '19 at 06:33
