If your application is not using Spring Boot, you are responsible for setting up the relevant Spring for GraphQL components.
Assuming that your application is already configured for Spring MVC controllers, the minimum setup will require several beans.

include-code::GraphQlConfiguration[]
<1> The `AnnotatedControllerConfigurer` bean is responsible for detecting GraphQL `@Controller` handlers.
<2> The `ExecutionGraphQlService` processes GraphQL requests in a transport-agnostic fashion.
<3> The `GraphQlSource` builder is the main configuration point. Explore its API for more options.
<4> The `RouterFunction` exposes the GraphQL routes as {spring-framework-ref-docs}/web/webmvc-functional.html[functional endpoints].
<5> You can then expose various transports (WebSocket, SSE, HTTP) over different routes.

Spring for GraphQL offers many other options and integrations with Spring projects.
For more on this, you can xref:boot-starter.adoc[explore the Spring Boot auto-configurations].
