Unable to run spring-boot-webflux sample

[oooplz]

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.

The AutoConfiguration class doesn't seems to work well with the @componentscan. The graphql.kickstart.spring.webflux.ReactiveWebSocketSubscriptionsHandler didn't pick up by spring.

I have to add this to my configuration class.

    @Bean
    @ConditionalOnMissingBean
    ReactiveWebSocketSubscriptionsHandler reactiveWebSocketSubscriptionsHandler(ReactiveSubscriptionsProtocolFactory factory) {
        return new ReactiveWebSocketSubscriptionsHandler(factory);
    }

I think adding above snippet to the GraphQLSpringWebfluxAutoConfiguration.java should work too. But I don't have enough confident that it solved the primary cause.

Sorry for the comment spam. But for my case, the component scan doesn't seem to work at all.

Now my configuration class is look like this:

package test;

import graphql.kickstart.execution.GraphQLInvoker;
import graphql.kickstart.execution.GraphQLObjectMapper;
import graphql.kickstart.spring.GraphQLSpringInvocationInputFactory;
import graphql.kickstart.spring.webflux.GraphQLController;
import graphql.kickstart.spring.webflux.ReactiveSubscriptionsProtocolFactory;
import graphql.kickstart.spring.webflux.ReactiveWebSocketSubscriptionsHandler;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class MyTestConfiguration {

    @Bean
    @ConditionalOnMissingBean
    ReactiveWebSocketSubscriptionsHandler reactiveWebSocketSubscriptionsHandler(ReactiveSubscriptionsProtocolFactory factory) {
        return new ReactiveWebSocketSubscriptionsHandler(factory);
    }

    @Bean
    @ConditionalOnMissingBean
    GraphQLController graphQLController(GraphQLObjectMapper objectMapper, GraphQLInvoker graphQLInvoker, GraphQLSpringInvocationInputFactory invocationInputFactory) {
        return new GraphQLController(objectMapper, graphQLInvoker, invocationInputFactory);
    }
}

Not sure if the ConditionalOnBean added in the [d865b8c] breaks the ComponentScan.

Hello to all. If we remove the @ConditionalOnBean ({GraphQLSchema.class}) annotation in the public class GraphQLSpringWebfluxAutoConfiguration, it works fine.
