Answer 1

I also had the same error:

***************************
APPLICATION FAILED TO START
***************************

Description:

Field repository in com.example.controller.CampaignController required a bean of type 'com.example.data.CustomerRepository' that could not be found.


Action:

Consider defining a bean of type 'com.example.data.CustomerRepository' in your configuration.de here

I solved this issue by adding @EnableMongoRepositories annotation in the main class:

@SpringBootApplication
@EnableMongoRepositories(basePackageClasses = CustomerRepository.class)
public class CampaignAPI {

    public static void main(String[] args) {
        SpringApplication.run(CampaignAPI.class, args);
    }
}
