Class FederationSchemaFactory

java.lang.Object

org.springframework.graphql.data.method.annotation.support.AnnotatedControllerDetectionSupport<FederationSchemaFactory.EntityMappingInfo>

org.springframework.graphql.data.federation.FederationSchemaFactory

All Implemented Interfaces:

Aware, InitializingBean, ApplicationContextAware

public final class FederationSchemaFactory
extends AnnotatedControllerDetectionSupport<FederationSchemaFactory.EntityMappingInfo>

Detects @EntityMapping handler methods on controllers declared in Spring configuration, and provides factory methods to create GraphQLSchema or SchemaTransformer.

This class is intended to be declared as a bean in Spring configuration, and plugged in via GraphQlSource.SchemaResourceBuilder.schemaFactory(BiFunction).

createGraphQLSchema

public GraphQLSchema createGraphQLSchema(TypeDefinitionRegistry registry,
 RuntimeWiring wiring)

Create GraphQLSchema via SchemaTransformer, setting up the "_entities" DataFetcher and TypeResolver for federated types.

Use this to supply a schemaFactory.

Parameters:

registry - the existing type definition registry

wiring - the existing runtime wiring

createSchemaTransformer

public com.apollographql.federation.graphqljava.SchemaTransformer createSchemaTransformer(TypeDefinitionRegistry registry,
 RuntimeWiring wiring)

Alternative to createGraphQLSchema(TypeDefinitionRegistry, RuntimeWiring) that allows calling additional methods on SchemaTransformer.

Parameters:

registry - the existing type definition registry

wiring - the existing runtime wiring
