Ahead Of Time support

[bclozel]

Since Spring Framework has been working on AOT and GraalVM Native Image support, we should consider improvements to make this work in time for 1.1.0.

Right now we're identifying several tasks:

• make sure that the scanning of schema files is supported. This should be taken care of in Use java.nio and FileSystems to resolve files in PathMatchingResourcePatternResolver spring-framework#29163
• Contribute reachability metadata for GraphQL Java 19.2, see Add support for GraphQL Java 19.2 oracle/graalvm-reachability-metadata#102
• Create a dedicated issue in Spring Boot for resource hints (the graphiql HTML UI and the schema resources), see Contribute missing resource hints for GraphQL schema files and GraphiQL HTML page spring-boot#33208
• Implement a BeanFactoryInitializationAotProcessor in Spring for GraphQL that registers RuntimeHints for controllers, @SchemaMapping + @BatchMapping methods, Java application types tied to the GraphQL schema and proxying support for @ProjectedPayload support. This should be done as part if this issue.

Hi @bclozel , I have meet another issue with opening GraphlQL websocket using webflux stack when I run native application. From my briftly analysis it looks like there is missing dependency or missing hint.

I don't know where should I report an issue? Just here is enough, or maybe create another one?

I have prepared simple repository where you can see full configuration of project and fell free to try yourself. Please find the link below: https://github.com/rafallezanko/spring_native_graphql_error_example/tree/master

When I start application I receive No JSON Encoder exception from CodecDelegate class:

@rafallezanko this issue is still opened, so GraalVM Native is not supported yet with Spring for GraphQL.
