Couldn autowire. Spring boot

Пытаюсь создать контроллер spring boot. Проект разбит на несколько модулей: dao, entities, services, controllers.

    package dao.repository;
    import entities.Movie;
    import org.springframework.data.jpa.repository.JpaRepository;
    import org.springframework.stereotype.Repository;
    @Repository
    public interface MovieRepository extends JpaRepository<Movie, Integer> {
        Movie findByTitle(String title);
    }

    package impl;
    import dao.repository.MovieRepository;
    import entities.Movie;
    import interfaces.MovieCrudService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Service;
    import java.util.List;
    @Service
    public class MovieCrudServiceImpl implements MovieCrudService {
      @Autowired private MovieRepository movieRepository;
      @Override
      public List<Movie> getAllMovies() {
        return movieRepository.findAll();
      }
      @Override
      public Movie getMovieByID(int id) {
        return movieRepository.findOne(id);
      }
      @Override
      public Movie getMovieByTitle(String title) {
        return movieRepository.findByTitle(title);
      }
      @Override
      public void createMovie(Movie movie) throws Exception {
        movieRepository.saveAndFlush(movie);
      }
      @Override
      public void updateMovie(Movie movie) {
        movieRepository.saveAndFlush(movie);
      }
      @Override
      public void deleteMovie(Movie movie) {
        movieRepository.delete(movie);
      }
    }

    package cashier;
    import interfaces.MovieCrudService;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.RequestMethod;

    @Controller
    public class ShowMoviesController {
        @Autowired
        private MovieCrudService movieService;
        @RequestMapping(value = { "/showMovies" }, method = RequestMethod.GET)
        public String viewPersonList(Model model) {
            model.addAttribute("movies", movieService.getAllMovies());
            return "showMovies";
        }
    }

Но при попытке запустить Application:

    package app;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;

    @SpringBootApplication(scanBasePackages = {"cashier"})
    public class Application {
      public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
      }
    }

Пишет ошибку:

    ***************************
    APPLICATION FAILED TO START
    ***************************
    Description:
    Field movieService in cashier.ShowMoviesController required a bean of type 'interfaces.MovieCrudService' that could not be found.

    Action:
    Consider defining a bean of type 'interfaces.MovieCrudService' in your configuration.

Каким образом это можно исправить?
