dgs-framework: bug: DGS Framework not working with Spring Boot 3

Hi guys.

With the new release of Spring Framework 6 and Spring Boot 3, I decided to upgrade my existing Spring Boot application. After going through the pain of changing the codebase to be compatible with Spring Boot 3, I realized that GQL queries using the DGS Framework stopped working with a 404. Reverting to Spring Boot 2.x and everything works as expected.

Expected behavior

Should be able to hit the configured GraphQL endpoint.

Actual behavior

You get similar error:

{"timestamp":"...","status":404,"error":"Not Found","message":"No message available","path":"/graphql (or your configured endpoint)"}

Steps to reproduce

• Create new two projects, one a Spring Boot 3 and the other Spring Boot 2.x.
• Add required DGS Framework dependencies.
• Create similar schema for both projects
• Start both projects (on different ports at the same time or one after the other).

Spring Boot 2.x project displays c.n.g.d.w.a.GraphiQLConfigurer : Configuring GraphiQL to use GraphQL endpoint at '/graphql (or your configured endpoint)' in terminal signifying OK setup of DGS Framework. Spring Boot 3 project does not display any info in terminal and returns a 404 if a query request is made to the configured endpoint.

NB: Spring Boot 3 also displays the following warning:
