Multiple Database Configurations in Spring Boot

Question

I need to configure 2 MongoDB databases with my Spring Boot v3.0.5 application.

I have made 2 MongoDB configurations as follows:

RemindersConfig.java

@Configuration
@EnableReactiveMongoRepositories(basePackages = "com.shourya.learn.repository")
public class RemindersConfig extends AbstractReactiveMongoConfiguration {
    @Value("${mongodb.reminders.database}")
    private String database;

    @Bean(name = "reminders")
    public MongoClient mongoClient() {
        String uri = "mongodb://localhost:27017/" + database;
        return MongoClients.create(uri);
    }

    @Override
    protected String getDatabaseName() {
        return database;
    }
}

NotificationsConfig.java

@Configuration
@EnableReactiveMongoRepositories(basePackages = "com.shourya.learn.repository")
public class NotificationsConfig extends AbstractReactiveMongoConfiguration {
    @Value("${mongodb.notifications.database}")
    private String database;

    @Bean(name = "notifications")
    public MongoClient mongoClient() {
        String uri = "mongodb://localhost:27017/" + database;
        return MongoClients.create(uri);
    }

    @Override
    protected String getDatabaseName() {
        return database;
    }
}

Repositories:

NotificationRepository.java

@Repository
public interface NotificationRepository extends ReactiveMongoRepository<NotificationModel, String> {
}

ReminderRepository.java

@Repository("reminderRepository")
public interface ReminderRepository extends ReactiveMongoRepository<ReminderModel, String> {
}

They run fine individually but when run together they give the following error:

Description:

The bean 'reminderRepository', defined in com.shourya.learn.repository.ReminderRepository defined in @EnableReactiveMongoRepositories declared on RemindersConfig, could not be registered. A bean with that name has already been defined in com.shourya.learn.repository.ReminderRepository defined in @EnableReactiveMongoRepositories declared on NotificationsConfig and overriding is disabled.

Action:

Consider renaming one of the beans or enabling overriding by setting spring.main.allow-bean-definition-overriding=true
