Prior to this commit, the "client" and "testing" sections of the
reference documentation were using inline code snippets.
Because of this, several snippets were out of date or invalid.
This commit moves all those code snippets to actual Java classes
compiled with the documentation.
Fixes gh-1042
Most Spring for GraphQL applications use Spring Boot as a way to
auto-configure the required infrastructure for running GraphQL
applications.
This commit documents a minimal setup for Spring applications not
relying on Spring Boot. This assumes an existing infrastructure for a
Spring MVC application.
Closes gh-606
This commit documents the GraalVM Native image support in Spring for
GraphQL and lists relevant pointers to the Spring Framework and Spring
Boot documentations.
This also explains how developers are expected to provide reachability
hints for the cases where the AOT processing is not able to discover the
relevant types.
Closes gh-581
