Circular dependencies between spring included components?

Question

I have multiple applications that share the same configuration classes and once with spring boot v3 I received multiple circular dependencies errors. Most of them were legit mistakes from my side and I manage to refactor the code and fix them, but now I'm stuck with the following message for all the applications:


   webHandler defined in class path resource [org/springframework/boot/autoconfigure/web/reactive/WebFluxAutoConfiguration$EnableWebFluxConfiguration.class]
      ↓
   healthEndpointWebFluxHandlerMapping defined in class path resource [org/springframework/boot/actuate/autoconfigure/health/HealthEndpointReactiveWebExtensionConfiguration$WebFluxAdditionalHealthEndpointPathsConfiguration.class]

└─────┘

Not sure exactly how to proceed from here as I have no idea what it's actually casing this chain of dependencies.

I tried to remove the consul components and let only the default configuration, but without any luck.

Can you share the failure when you've removed the Consul components? — Andy Wilkinson, Jul 21 '23 at 14:03
Removing everything that's related to consul from dependency tree made the application run successfully. I had only two nested dependencies from consul: `org.springframework.cloud:spring-cloud-consul-discovery` and `com.ecwid.consul:consul-api`. Also I have consul heartbeat enabled via properties: `spring.cloud.consul.heartbeat.enabled=true` and if I disabled it everything works properly(with the consul dependencies included) — r.m.ghimis, Jul 21 '23 at 14:25
Can you share a minimal, reproducible example? The link between `mongoMappingContext` and `consulAutoServiceRegistrationListener` is surprising and I don't think it can be figured out without one. — Andy Wilkinson, Jul 21 '23 at 15:46

write something like this

@SpringBootApplication(exclude = MongoReactiveDataAutoConfiguration.class)

@Bean
@ConditionalOnMissingBean(ReactiveMongoDatabaseFactory.class)
public SimpleReactiveMongoDatabaseFactory reactiveMongoDatabaseFactory(MongoProperties properties,
                                                                       MongoClient mongo) {
    String database = properties.getMongoClientDatabase();
    return new SimpleReactiveMongoDatabaseFactory(mongo, database);
}

 @Bean
public ReactiveMongoTemplate reactiveMongoTemplate(ReactiveMongoDatabaseFactory factory) {
    return new ReactiveMongoTemplate(factory);
}
