Generated SubscriptionExecutor doesn't compile about graphql-maven-plugin-project HOT 8 CLOSED

Hum,

Please ignore the first comment I wrote. I'm too much switching from a language to another, these times.

Thanks to your git repo, I can repeat the bug. I'll work on this this week-end.

No problem 😄 Thank you for your efforts maintaining this plugin!

By the way, the issue doesn't seem to be related to the input fields named and, or, not. If I remove those the compilation error still happens.

Also, not actually related to this issue, but is there an example of how subscriptions work?

For me it seems the way it is implemented in graphql-java-generator doesn't follow the protocol used by eg. Dgraph, Hasura, Apollo, etc.:

Hum, it was closed by my commit comment.
So I reopen it.

For a sample, you can take a look at the allGraphQLCases, in the project.
I just add a subscription package to show the usage of this.
I’ll check the site documentation.

Yes, that's right. It's the reason why I changed my initial comment.

The issue was a quick complex one, due to the Java generic types. It was quite tricky to solve.
But stackoverflow has a lot of solutions!
:)

About the respect of protocol : as the server is handled by graphql-java, I guess it respects plainly the GraphQL protocol.
BTW, I tested it only agains a GraphQL server powered by graphql-java.

If there are issues there, I'll be glad to test it against other kind of servers.

And about a doc on how to use it:
The plugin web site has a page about this: https://graphql-maven-plugin-project.graphql-java-generator.com/client_subscription.html

You'll find a sample in the project itself: https://github.com/graphql-java-generator/graphql-maven-plugin-project/tree/master/graphql-maven-plugin-samples/graphql-maven-plugin-samples-allGraphQLCases-client/src/main/java/org/allGraphQLCases/subscription

I just released the 1.11.1 version.

Please tell me if everything is ok for you, now.

@etienne-sf thank you and stackoverflow so much! 😃 It compiles all right now! I really appreciate your quick response to this issue!

I will take a look at the examples as well, thanks.

I guess graphql-java only provides the websocket layer and doesn't bother with the message format sent over the line. But I will investigate it a bit too to see if I can make it work. You may also try to create a small Hasura setup and see whether graphql-java-generator subscriptions work with it.
