Unable to run spring-boot-webflux sample

[bbedrin]

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.

2020-05-24 21:41:42.289  INFO 23511 --- [           main] webflux.WebfluxApplication               : No active profile set, falling back to default profiles: default

Am I missing something else that isn't documented?

The bean is created by the starter automatically, you shouldn't have to create that manually. I just tried the sample and it's working fine for me. Main points to check are:

1. You have the same dependencies the sample is using
2. You have a GraphQL SDL file in your classpath with graphqls extension defining your schema

Those things are configured correctly in the sample project though, so should work.

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. Dependency annotations: {}

[oliemansm]

That's very strange... It uses component scan with a base package to find this bean automatically here https://github.com/graphql-java-kickstart/graphql-spring-boot/blob/0ab682cefb2358c8c7fb5473e84ee9e45fd6be12/graphql-kickstart-spring-boot-autoconfigure-webflux/src/main/java/graphql/kickstart/spring/webflux/boot/GraphQLSpringWebfluxAutoConfiguration.java#L54.

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 though.

Added this to a configuration, fixes the startup:

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

But then I get the following error in graphiql

I downloaded project source that spring-boot-webflux and not modify any file.

Appear exception information as flow:

Description:

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.

I am also facing similar issue.. I am using version 7.1.0 and I am getting /graphql not found.. any suggestion on how to solve this?

[kejistan]

This seems related to graphql-java-kickstart/graphql-spring-boot@d865b8c 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.

[conanchen]

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

7.1.0-SNAPSHOT the same

[aymanmoukhtar]

Any updates on this?

[Toerktumlare]

i am trying out the webflux 7.1.0 release, and i am getting this error.

Anyone that has any workaround?

[joaomlneto]

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 though.

Same problem, similar fix using the releases in the maven central repository.
Tried using release 7.1.0 and got this error. Using release 7.0.1 works fine.

[vojtapol]

We accept PRs if anyone is willing to fix this.

[pokebadgerswithspoon]

Seems this fixes the issue, at least spring-boot app starts with following config applied

@ComponentScans({
     @ComponentScan("graphql.kickstart.tools.boot"),
     @ComponentScan("graphql.kickstart.spring.webflux")
})

Will it be a good PR with the snippet applied to GraphQLSpringWebfluxAutoConfiguration.java?
