Spring Boot doesn't seem to find Repository

Question

I'm not sure what's wrong with my configuration, but as far as I can see it should be correct, despite that spring announces that there is no such bean definition. I veryfied these points:

• The configuration class is in the root package of everything else
• The repository extends JpaRepository, thus needs no annotation
• The player object is annotated with "@Entity"
• The pojo for this repository is completely mapped in terms of annotations
• No non-java configuration files present
• The database is set up and the correct credentials are used.
• Jpa/hibernate is set to "Create-Update" for development purposes.

Here's my complete debug log: spring startup log pastebin

Description:

Field playerRepository in de.awesome.corporate.newworlds.core.usermanagement.service.RegistrationService required a bean of type 'de.awesome.corporate.newworlds.core.usermanagement.repository.PlayerRepository' that could not be found.


Action:

Consider defining a bean of type 'de.awesome.corporate.newworlds.core.usermanagement.repository.PlayerRepository' in your configuration.

My SpringBootApplication:

package de.awesome.corporate.newworlds;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@SpringBootApplication
public class NewWorldsApplication {

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

My PlayerRepository:

package de.awesome.corporate.newworlds.core.usermanagement.repository;

import org.springframework.data.jpa.repository.JpaRepository;

import de.awesome.corporate.newworlds.core.usermanagement.entity.Player;

public interface PlayerRepository extends JpaRepository<Player, String>{

    Player findByUserAccount(String useraccount);

}

The calling Service:

package de.awesome.corporate.newworlds.core.usermanagement.service;
@Service
public class RegistrationService {

    @Autowired
    private PlayerRepository playerRepository;

    @Autowired
    private UserAccountRepository userRepository;

    @Autowired
    private OrganizationCreationService organizationCreationService;

    @Autowired
    private BCryptPasswordEncoder passwordEncoder;
}

EDIT: It seems that, after removing spring-data-jpa-starter from the pom, and then reinsert it, that it also has problems now autowiring the password encorder. Is there a general problem with the way spring does the autowiring?

Answer 1

Apparently, somewhere in the project structure, there was a different version of the repository, and a different version of the player.

While usually I would expect Spring to produce an error telling me that there are multiple services with the same type description, I suspect due to both player and playerRepository being duplicates, this mechanism did not produce the expected error method, but instead told me that there is no service of that name at all.
