Package org.springframework.graphql.data.method.annotation.support

Class AnnotatedControllerConfigurer

java.lang.Object

org.springframework.graphql.data.method.annotation.support.AnnotatedControllerConfigurer

All Implemented Interfaces:

Aware, InitializingBean, ApplicationContextAware, RuntimeWiringConfigurer

public class AnnotatedControllerConfigurer
extends Object
implements ApplicationContextAware, InitializingBean, RuntimeWiringConfigurer

RuntimeWiringConfigurer that finds @SchemaMapping annotated handler methods in @Controller classes declared in Spring configuration, and registers them as DataFetchers.

In addition to initializing a RuntimeWiring.Builder, this class, also provides an option to configure data fetchers on a GraphQLCodeRegistry.Builder.

This class detects the following strategies in Spring configuration, expecting to find a single, unique bean of that type:

• CursorStrategy -- if Spring Data is present, and the strategy supports ScrollPosition, then ScrollSubrangeMethodArgumentResolver is configured for use. If not, then SubrangeMethodArgumentResolver is added instead.
• SortStrategy -- if present, then SortMethodArgumentResolver is configured for use.

Since:

1.0.0

AnnotatedControllerConfigurer

public AnnotatedControllerConfigurer()

Method Details

addFormatterRegistrar

public void addFormatterRegistrar(FormatterRegistrar registrar)

Add a FormatterRegistrar to customize the ConversionService that assists in binding GraphQL arguments onto @Argument annotated method parameters.

addCustomArgumentResolver

public void addCustomArgumentResolver(HandlerMethodArgumentResolver resolver)

Add a HandlerMethodArgumentResolver for custom controller method arguments. Such custom resolvers are ordered after built-in resolvers except for SourceMethodArgumentResolver, which is always last.

Parameters:

resolver - the resolver to add.

Since:

1.2

getExceptionResolver

public DataFetcherExceptionResolver getExceptionResolver()

Return a DataFetcherExceptionResolver that resolves exceptions with @GraphQlExceptionHandler methods in @ControllerAdvice classes declared in Spring configuration. This is useful primarily for exceptions from non-controller DataFetchers since exceptions from @SchemaMapping controller methods are handled automatically at the point of invocation.

Returns:

a resolver instance that can be plugged into GraphQlSource.Builder

Since:

1.2

setDataBinderInitializer

@Deprecated(since="1.1.0",
            forRemoval=true)
public void setDataBinderInitializer(@Nullable
 Consumer<DataBinder> consumer)

Deprecated, for removal: This API element is subject to removal in a future version.

this property is deprecated, ignored, and should not be necessary as a DataBinder is no longer used to bind arguments

Configure an initializer that configures the DataBinder before the binding process.

Parameters:

consumer - the data binder initializer

Since:

1.0.1

setExecutor

public void setExecutor(Executor executor)

Configure an Executor to use for asynchronous handling of Callable return values from controller methods.

By default, this is not set in which case controller methods with a Callable return value cannot be registered.

Parameters:

executor - the executor to use

setApplicationContext

public void setApplicationContext(ApplicationContext applicationContext)

Specified by:

setApplicationContext in interface ApplicationContextAware

afterPropertiesSet

public void afterPropertiesSet()

Specified by:

afterPropertiesSet in interface InitializingBean

obtainApplicationContext

protected final ApplicationContext obtainApplicationContext()

configure

public void configure(RuntimeWiring.Builder runtimeWiringBuilder)

Description copied from interface: RuntimeWiringConfigurer

Apply changes to the RuntimeWiring.Builder such as registering DataFetchers, custom scalar types, and more.

Specified by:

configure in interface RuntimeWiringConfigurer

Parameters:

runtimeWiringBuilder - the builder to configure

configure

public void configure(GraphQLCodeRegistry.Builder codeRegistryBuilder)

Alternative to configure(RuntimeWiring.Builder) that registers data fetchers in a GraphQLCodeRegistry.Builder. This could be used with programmatic creation of GraphQLSchema.
