samples: Unable to run spring-boot-webflux sample

Hi,

I was trying to implement the graphql-kickstart-spring-boot-starter-webflux and kept running into the below error. I tried cloning the sample spring-boot-webflux repo, but ran into the same issue as well.

Parameter 1 of method webSocketHandlerMapping in graphql.kickstart.spring.webflux.boot.GraphQLSpringWebfluxAutoConfiguration required a bean of type 'graphql.kickstart.spring.webflux.ReactiveWebSocketSubscriptionsHandler' that could not be found.

Action:

Consider defining a bean of type 'graphql.kickstart.spring.webflux.ReactiveWebSocketSubscriptionsHandler' in your configuration.

When I then try to implement a bean of ReactiveWebSocketSubscriptionsHandler, it resolves the startup error but doesn’t start

@Bean
	public ReactiveWebSocketSubscriptionsHandler reactiveWebSocketSubscriptionsHandler(ReactiveSubscriptionsProtocolFactory subscriptionProtocolFactory) {
		return new ReactiveWebSocketSubscriptionsHandler(subscriptionProtocolFactory);
	}

But it doesn’t start up the /graphql or /subscription endpoints.

Am I missing something else that isn’t documented?

I’m running into the same error using the 7.1.0-SNAPSHOT. I don’t have this problem with the 7.0.2-SNAPSHOT thoug

This seems related to https://github.com/graphql-java-kickstart/graphql-spring-boot/commit/d865b8cee499685ac2e155915cff576cc424bc3c Like @Racv I’m also not seeing my /graphql endpoint. I’m defining my own graphql.schema.GraphQLSchema bean but the autoconfiguration report lists GraphQLSpringWebfluxAutoConfiguration in the negative matches section:

GraphQLSpringWebfluxAutoConfiguration:
   Did not match:
      - @ConditionalOnBean (types: graphql.schema.GraphQLSchema; SearchStrategy: all) did not find any beans of type graphql.schema.GraphQLSchema (OnBeanCondition)
   Matched:
      - @ConditionalOnBean (types: graphql.schema.GraphQLSchema; SearchStrategy: all) found bean 'graphQLSchema' (OnBeanCondition)

EDIT: From some further experimentation it seems like the report is slightly misleading and GraphQLSpringWebfluxAutoConfiguration beans are being added but the controller and other graphql.kickstart.spring.webflux beans are not. There may be something odd with the conditional and ComponentScan: https://stackoverflow.com/questions/38474382/componentscan-doesnt-work-in-spring-boot-autoconfiguration-class

This doc suggests that using ComponentScan in an autoconfiguration might simply be unsupported.

Furthermore, auto-configuration classes should not enable component scanning to find additional components. Specific @Imports should be used instead.

Hi,

I did a fresh install of the sample and still cant run the application.

Where is the bean registered? I took a look for it in the main repository and cannot find it. https://github.com/graphql-java-kickstart/graphql-spring-boot/blob/master/graphql-kickstart-spring-boot-autoconfigure-webflux/src/main/java/graphql/kickstart/spring/webflux/boot/GraphQLSpringWebfluxAutoConfiguration.java

Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'webHandler' defined in class path resource [org/springframework/boot/autoconfigure/web/reactive/WebFluxAutoConfiguration$EnableWebFluxConfiguration.class]: Initialization of bean failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'webSocketHandlerMapping' defined in class path resource [graphql/kickstart/spring/webflux/boot/GraphQLSpringWebfluxAutoConfiguration.class]: Unsatisfied dependency expressed through method 'webSocketHandlerMapping' parameter 1; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'graphql.kickstart.spring.webflux.ReactiveWebSocketSubscriptionsHandler' available: expected at least 1 bean which qualifies as autowire candidate.
