Browse Source 
This commit contributes a `RSocketGraphQlClient.Builder` component to
the context, pre-configured with the `RSocketStrategies`, a customized
`RSocketConnector` and the expected data MIME type.

RSocket is also supported as a transport, on top of WebSocket or TCP.
Once the <<messaging#messaging.rsocket.server-auto-configuration,RSocket server is configured>>, we can configure our GraphQL handler on a particular route using configprop:spring.graphql.rsocket.mapping[].
For example, configuring that mapping as `"graphql"` means we can use the `RSocketGraphQlClient` as follows.
For example, configuring that mapping as `"graphql"` means we can use that as a route when sending requests with the `RSocketGraphQlClient`.
For RSocket over TCP:
include::code:RSocketGraphQlClientExample[tag=tcp]
Spring Boot auto-configures a `RSocketGraphQlClient.Builder<?>` bean that you can inject in your components:
For RSocket over WebSocket:
include::code:RSocketGraphQlClientExample[tag=websocket]
include::code:RSocketGraphQlClientExample[tag=builder]
And then send a request:
include::code:RSocketGraphQlClientExample[tag=request]
