Spring Boot – Loading Initial Data

I’m wondering what the best way to load initial database data before the application starts? What I’m looking for is something that will fill my H2 database with data.

For example, I have a domain model “User” I can access users by going to /users but initially there won’t be any users in the database so I have to create them. Is there anyway to fill the database with data automatically?

At the moment I have a Bean that gets instantiated by the container and creates users for me.

Example:

@Component
public class DataLoader {

    private UserRepository userRepository;

    @Autowired
    public DataLoader(UserRepository userRepository) {
        this.userRepository = userRepository;
        LoadUsers();
    }

    private void LoadUsers() {
        userRepository.save(new User("lala", "lala", "lala"));
    }
}

But I very much doubt that is the best way of doing it. Or is it?
