Mongo tenta di connettersi automaticamente alla porta 27017 (localhost)

Question

Sto utilizzando Spring Rest e Mongo in Maven per creare un servizio Web che si connette a un server. Il problema è che non ho scritto alcun codice per Mongo e sta provando a collegarmi a localhost gettandomi una MongoSocketOpenException. L'unico codice che ho scritto è un codice a due riga che inizia la primavera dal main.This è lo stacktrace:

Infine devo dire che, nonostante l'eccezione il programma funziona bene

Grazie in anticipo!

Answer 1

Spring Boot ha una funzionalità denominata "configurazione automatica". In questo caso, non appena viene rilevato il driver Mongo sul classpath, MongoAutoConfiguration viene attivato con i valori predefiniti, che puntano a localhost: 27017. Se non si desidera che il comportamento, è ora possibile configurare le proprietà sia per MongoDB (vedi http://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#boot-features-mongodb per chiavi di proprietà validi) o disabilitare il MongoAutoConfiguration:

@SpringBootApplication(exclude = {MongoAutoConfiguration.class, MongoDataAutoConfiguration.class})
