The brief

A movie aficionado is buying and collecting movies in the mp4 format on an external 2 TB hard-drive. So far he has tried to use a system where he puts them in different folders, depending on their rating and the category of the movie. As the collection has grown the categories is becoming an increasing problem. Here we come with a solution !

Application design

Our application was design by us in Figma

Database design

MSSQL Database diagram

UML diagram

Application design patterns

• Singleton pattern
• Dependency injection pattern
• Factory pattern
• Publish-subscribe-style communication
• Data-access-object
• Service pattern

Data Access Object

Example Method to retrieve movie by its category ID with com.movie_collection.dal.myBatis and SL4J

• Additional mapping included in Movie.xml

@Override
public Optional<List<Movie>> getAllMoviesInTheCategoryById(int categoryId) {
    List<Movie> fetchedMovieInRole = new ArrayList<>();
    try (SqlSession session = MyBatisConnectionFactory.getSqlSessionFactory().openSession()) {
        MovieMapperDAO mapper = session.getMapper(MovieMapperDAO.class);
        fetchedMovieInRole = mapper.getAllMoviesByCategoryId(categoryId);
    } catch (Exception ex) {
        logger.error("An error occurred mapping tables", ex);
    }
    return Optional.ofNullable(fetchedMovieInRole);
}

DI Guice

Dependency injection pattern example of injecting a model via class construct

private IMovieDAO movieDAO;

@Inject
public MovieService(IMovieDAO movieDAO) {
    this.movieDAO = movieDAO;
}

OpenFeign /w API

RESTful web service to obtain movie information

• http://www.omdbapi.com
• API contract call to get movie by title
• Environmental variables / sensitive credentials handeling
• Custom logger stored in logs

public interface IMovie {
      @Headers({"Content-Type: application/json","apikey: {apikey}"})
      @RequestLine("GET /?t={title}")
      MovieDTO movieByName(@Param("title") String title);
}

FXML Factory Controller with Guice DI injection

@Override
public RootController loadFxmlFile(ViewType fxmlFile) throws IOException {
      final URL fxmlFileUrl = Main.class.getResource(fxmlFile.getFXMLView());

      final FXMLLoader loader = new FXMLLoader(fxmlFileUrl);
      loader.setControllerFactory(injector::getInstance);

      final Parent view = loader.load();
      final RootController controller = loader.getController();
      controller.setView(view);

      return controller;
    }

Abstract root controller

• Implementation of a simple abstract class that set and retrieves Parent root object

public abstract class RootController implements IRootController {
    protected Parent root;

    @Override
    public Parent getView() {
        return root;
    }

    @Override
    public void setView(Parent node){
       this.root = Objects.requireNonNull(node, "view must not be null.");
    }
}
