In @src/main/java/org/example/ItunesApiClient.java:
- Around line 42-44: Replace Swedish comments and error text in ItunesApiClient
with English for consistency: change the comment preceding the
response.statusCode() check ("Kontrollera status") to an English comment like
"Check response status" and update the RuntimeException message ("API-fel: ") to
an English message such as "API error: " plus the status code; likewise convert
the nearby JSON parse comment ("Parse JSON") to "Parse JSON". Locate these
within the method that performs the HTTP request/response handling in class
ItunesApiClient and update the comment strings and exception message
accordingly.
In @src/main/java/org/example/ItunesPlayList.java:
- Around line 336-344: DisplaySong instances are compared by reference when
using contains(), so duplicate detection fails; implement
DisplaySong.equals(Object) and hashCode() to compare the meaningful fields
(name, artist, album, time) so two DisplaySong objects with identical data are
considered equal; update the DisplaySong class (constructor remains same) to
override equals and hashCode using those fields (null-safe) so contains() and
any hashing collections behave correctly.
- Line 199: Replace use of the deprecated resize policy constant: locate the
call songTable.setColumnResizePolicy(...) and change the argument from
TableView.CONSTRAINED_RESIZE_POLICY to
TableView.CONSTRAINED_RESIZE_POLICY_ALL_COLUMNS so the TableView uses the
non-deprecated all-columns constrained policy.
In @src/main/java/org/example/repo/PlaylistRepositoryImpl.java:
- Around line 8-44: PlaylistRepositoryImpl currently contains stubs; implement
JPA-backed logic using the PersistenceManager's EntityManagerFactory (emf)
similar to AlbumRepositoryImpl/SongRepositoryImpl: use emf.callInTransaction for
read methods findAll() and findSongsInPlaylist(Playlist) with JPQL queries
against the Playlist entity (e.g., "SELECT p FROM Playlist p" and fetching songs
via JOIN FETCH or retrieving playlist by id), and use emf.runInTransaction for
mutating methods createPlaylist(String), deletePlaylist(Playlist),
addSong(Playlist, Song), removeSong(Playlist, Song), and
renamePlaylist(Playlist, String) to persist/merge/remove entities and properly
manage the many-to-many association between Playlist and Song (update both sides
if necessary and merge the Playlist entity). Ensure you reference
PlaylistRepositoryImpl, PersistenceManager, emf.callInTransaction,
emf.runInTransaction, and the Playlist/Song entities in your changes.
🧹 Nitpick comments (20)
src/main/java/org/example/PersistenceManager.java (1)
16-35: Consider error handling for database unavailability.If the database is unavailable when this class is loaded, the static initializer will throw an exception that can be difficult to diagnose. The shutdown hook is good for cleanup, but consider wrapping the initialization in a try-catch with a clear error message.
🔎 Suggested improvement
static { + try { List<Class<?>> entities = getEntities("org.example.entity"); final PersistenceConfiguration cfg = new HibernatePersistenceConfiguration("emf") .jdbcUrl("jdbc:mysql://localhost:3306/myPodDB") .jdbcUsername("user") .jdbcPassword("pass") .property("hibernate.hbm2ddl.auto", "update") .property("hibernate.show_sql", "true") .property("hibernate.format_sql", "true") .property("hibernate.highlight_sql", "true") .managedClasses(entities); emf = cfg.createEntityManagerFactory(); - //From CodeRabbit: Register a shutdown hook to properly release database connections on JVM exit. Runtime.getRuntime().addShutdownHook(new Thread(emf::close)); + } catch (Exception e) { + throw new ExceptionInInitializerError("Failed to initialize EntityManagerFactory. Is the database running? " + e.getMessage()); + } }docker-compose.yml (1)
1-15: Security: Hardcoded credentials in version control.For a classroom project this is acceptable, but note that production deployments should use environment variables or secrets management. Also,
MYSQL_ROOT_HOST: "%"allows root connections from any host, which is a security risk.pom.xml (1)
75-107: Remove redundant source/target configuration from maven-compiler-plugin.Since you've set
maven.compiler.release=25in properties, the explicit<source>25</source>and<target>25</target>elements in the plugin configuration are unnecessary. Modern Maven (plugin 3.13.0+) will use the release property automatically. Remove the configuration block from the plugin to keep the pom.xml clean.src/main/java/org/example/repo/SongRepository.java (1)
20-21: Resolve the uncertainty aboutfindByAlbummethod.The comment indicates uncertainty about whether this method is redundant. If the
Albumentity maintains a bidirectional relationship withSong(e.g.,album.getSongs()), this method might be unnecessary. However, repository methods can still provide value for querying without loading the full entity graph.Do you want me to:
- Check if
Albumhas a collection of songs that would make this redundant?- Help you decide based on your query patterns and performance needs?
src/main/java/org/example/ItunesApiClient.java (1)
31-31: Consider making the result limit configurable.The hardcoded
limit=8reduces flexibility. Consider making this a parameter or class-level configuration to support different use cases.🔎 Example refactor
- public List<ItunesDTO> searchSongs(String term) throws Exception { + public List<ItunesDTO> searchSongs(String term, int limit) throws Exception { String encodedTerm = URLEncoder.encode(term, StandardCharsets.UTF_8); - String url = "https://itunes.apple.com/search?term=" + encodedTerm + "&entity=song&attribute=artistTerm&limit=8"; + String url = "https://itunes.apple.com/search?term=" + encodedTerm + "&entity=song&attribute=artistTerm&limit=" + limit;Or add a default method:
public List<ItunesDTO> searchSongs(String term) throws Exception { return searchSongs(term, 8); }src/main/java/org/example/DatabaseInitializer.java (1)
44-61: Consider wrapping entity creation in a single transaction per DTO.Each Artist, Album, and Song is persisted in separate transactions with individual
existsByUniqueIdchecks. While this provides idempotency, it lacks atomicity for the logical unit (one DTO → one complete Artist/Album/Song graph).If an exception occurs mid-processing, you may end up with an Artist and Album persisted but no Song. For more robust initialization, consider wrapping the entire entity graph creation for each DTO in a single transaction.
💡 Example approach
apiClient.searchSongs(term).forEach(dto -> { // Wrap the entire DTO processing in one transaction emf.runInTransaction(em -> { Artist ar = Artist.fromDTO(dto); if (!artistRepo.existsByUniqueId(ar)) { artistRepo.save(ar); } Album al = Album.fromDTO(dto, ar); if (!albumRepo.existsByUniqueId(al)) { albumRepo.save(al); } Song s = Song.fromDTO(dto, al); if (!songRepo.existsByUniqueId(s)) { songRepo.save(s); } }); });Note: This assumes PersistenceManager's EntityManagerFactory exposes
runInTransaction.src/main/java/org/example/repo/SongRepositoryImpl.java (1)
18-32: Use transactional helpers consistently with other repository implementations.The
count()andexistsByUniqueId()methods use try-with-resources, while all other methods in this class useemf.callInTransactionoremf.runInTransaction. This is inconsistent withAlbumRepositoryImpl(lines 14-21, 53-58), which uses the transactional helpers for all operations including count and existence checks.Using the transactional helpers ensures consistent transaction management across all repository operations.
🔎 Proposed refactor for consistency
@Override public Long count() { - try (var em = emf.createEntityManager()) { - return em.createQuery("select count(s) from Song s", Long.class) - .getSingleResult(); - } + return emf.callInTransaction(em -> + em.createQuery("select count(s) from Song s", Long.class) + .getSingleResult()); } @Override public boolean existsByUniqueId(Song song) { - try (var em = emf.createEntityManager()) { - return em.createQuery("select count(s) from Song s where s.songId = :songId", Long.class) - .setParameter("songId", song.getSongId()) - .getSingleResult() > 0; - } + return emf.callInTransaction(em -> + em.createQuery("select count(s) from Song s where s.songId = :songId", Long.class) + .setParameter("songId", song.getSongId()) + .getSingleResult() > 0); }src/main/java/org/example/entity/Playlist.java (1)
19-28: Missing getter forsongscollection and incomplete bidirectional synchronization.
There's no
getSongs()method, which will prevent accessing the songs in a playlist from other layers.Since
Songhas a@ManyToMany(mappedBy = "songs")relationship back toPlaylist,addSong/removeSongshould synchronize both sides to avoid inconsistency when entities are detached or when navigating from theSongside.🔎 Proposed fix
+ public Set<Song> getSongs() { + return songs; + } + public void addSong(Song song) { this.songs.add(song); + song.getPlaylist().add(this); } public void removeSong(Song song) { this.songs.remove(song); + song.getPlaylist().remove(this); }src/main/java/org/example/entity/Album.java (3)
7-7: Unused import.
java.time.LocalDateis imported but never used in this file.-import java.time.LocalDate;
27-32: Remove commented-out code.Dead code clutters the codebase and reduces readability. If these alternatives are no longer needed, remove them.
-// @OneToMany(mappedBy = "album") - //private List<Song> song; - - // @ManyToOne(cascade = CascadeType.PERSIST) - // @JoinColumn(name="artist_id") - // private Artist artist; -
38-39: Consider renamingsongtosongsfor clarity.Collection fields are conventionally named in plural form. This applies to the getter/setter as well (
getSongs()/setSongs()).src/main/java/org/example/entity/Artist.java (1)
22-23: Consider renamingalbumtoalbumsfor clarity.Collection fields are conventionally named in plural form, consistent with the suggested change in
Album.java.src/main/java/org/example/entity/Song.java (2)
7-7: Unused import.
java.time.LocalDateis imported but never used.-import java.time.LocalDate;
27-28: Consider renamingplaylisttoplaylistsfor clarity.This collection field represents multiple playlists, so a plural name would be more accurate.
src/main/java/org/example/MyPod.java (4)
360-373: Unused variable and error handling concern.The
emfvariable on line 362 is fetched but never used. If it's meant to ensure theEntityManagerFactoryis initialized, consider making that intent explicit.Also, the catch block silently logs to
stderrbut the callingTaskwon't triggeronFailedsince the exception is caught. Consider rethrowing or using a different error handling strategy.🔎 Proposed fix
private void initializeData() { - try { - EntityManagerFactory emf = PersistenceManager.getEntityManagerFactory(); + try { + // Ensure EMF is initialized (side effect of static initializer) + PersistenceManager.getEntityManagerFactory(); DatabaseInitializer initializer = new DatabaseInitializer(apiClient, songRepo, albumRepo, artistRepo); initializer.init(); // Fyll databasen om den är tom // Hämta data till minnet this.songs = songRepo.findAll(); this.artists = artistRepo.findAll(); this.albums = albumRepo.findAll(); } catch (Exception e) { System.err.println("Kunde inte ladda data: " + e.getMessage()); + throw new RuntimeException("Data initialization failed", e); } }
105-107: Background thread should be a daemon thread.If the application exits while this thread is running, it could prevent JVM shutdown. Mark it as a daemon thread to ensure clean exit.
🔎 Proposed fix
- new Thread(initTask).start(); + Thread initThread = new Thread(initTask); + initThread.setDaemon(true); + initThread.start();
111-116: Potential NullPointerException when loading CSS.If
getResource("/ipod_style.css")returnsnull, callingtoExternalForm()will throw an NPE, which is caught but the cause is obscured. A null check would provide clearer error messaging.🔎 Proposed fix
try { - // Försök ladda CSS-filen för styling - scene.getStylesheets().add(getClass().getResource("/ipod_style.css").toExternalForm()); + var cssUrl = getClass().getResource("/ipod_style.css"); + if (cssUrl != null) { + scene.getStylesheets().add(cssUrl.toExternalForm()); + } else { + System.out.println("CSS hittades inte, kör utan styling."); + } } catch (Exception e) { System.out.println("CSS hittades inte, kör utan styling."); }
351-354: Selecting "Playlists" repeatedly opens multiple windows.Each selection of "Playlists" creates a new
ItunesPlayListinstance and shows a newStage. Consider tracking the window and reusing/focusing it if already open.src/main/java/org/example/ItunesPlayList.java (2)
213-236: Creating a newFilteredListon every keystroke is inefficient.Consider creating a single
FilteredListper playlist and updating its predicate instead of constructing a new one each time.🔎 Suggested approach
- private void filterSongs(String searchText) { - String currentList = sourceList.getSelectionModel().getSelectedItem(); - if (currentList == null) return; - - ObservableList<DisplaySong> masterData = allPlaylists.get(currentList); - - if (searchText == null || searchText.isEmpty()) { - songTable.setItems(masterData); - return; - } - - FilteredList<DisplaySong> filteredData = new FilteredList<>(masterData, song -> { - String filter = searchText.toLowerCase(); - return song.name.toLowerCase().contains(filter) || - song.artist.toLowerCase().contains(filter) || - song.album.toLowerCase().contains(filter); - }); - - songTable.setItems(filteredData); - } + // Store filtered list at class level and update predicate instead + private FilteredList<DisplaySong> currentFilteredList; + + private void filterSongs(String searchText) { + if (currentFilteredList == null) return; + + if (searchText == null || searchText.isEmpty()) { + currentFilteredList.setPredicate(null); + } else { + String filter = searchText.toLowerCase(); + currentFilteredList.setPredicate(song -> + song.name.toLowerCase().contains(filter) || + song.artist.toLowerCase().contains(filter) || + song.album.toLowerCase().contains(filter)); + } + }Then initialize
currentFilteredListwhen playlist selection changes.
141-143: Potential NullPointerException when loading CSS.Same issue as in
MyPod.java- ifgetResource()returnsnull, this will throw an NPE.🔎 Proposed fix
- scene.getStylesheets().add(getClass().getResource("/ipod_style.css").toExternalForm()); + var cssUrl = getClass().getResource("/ipod_style.css"); + if (cssUrl != null) { + scene.getStylesheets().add(cssUrl.toExternalForm()); + }

1-125: LGTM! Static analysis warnings are false positives.The Biome linter is flagging
-fx-*properties as unknown because it's designed for web CSS. These are valid JavaFX CSS properties that follow JavaFX's CSS syntax (e.g.,-fx-background-color,-fx-fill,-fx-font-family). The stylesheet correctly implements an iPod-inspired theme for the JavaFX UI.src/main/java/org/example/PersistenceManager.java (1)

src/main/java/org/example/repo/ArtistRepository.java (1)
7-17: LGTM!Clean repository interface following the repository pattern. The method signatures are appropriate for the use case.
One optional consideration:
existsByUniqueId(Artist artist)could be simplified toexistsByUniqueId(Long artistId)since only the ID is needed to check existence. However, the current signature works well with theArtist.fromDTO()factory method pattern used inDatabaseInitializer.src/main/java/org/example/ItunesDTO.java (1)

@JsonIgnoreProperties(ignoreUnknown = true)provides good resilience against API changes. ThereleaseYear()convenience method appropriately handles null values.src/main/java/org/example/repo/AlbumRepository.java (1)
8-21: LGTM! Well-structured repository interface.The interface provides a clear contract for Album data access operations with appropriate query methods for common use cases (by artist, by genre).
src/main/java/org/example/repo/ArtistRepositoryImpl.java (3)
15-22: LGTM! Proper existence check implementation.The
existsByUniqueIdmethod correctly uses a count query to check for existing artists by their iTunes API identifier.
29-41: LGTM! Standard query implementations.The
findAll()andcount()methods follow standard JPA patterns with proper transaction handling.
24-27: No changes needed; the current implementation is correct.The
save()method usingpersist()is appropriate for this codebase. The code consistently follows a defensive pattern where every call tosave()is guarded by anexistsByUniqueId()check that prevents persisting entities that already exist. Entities passed tosave()are always transient (freshly created from DTOs), makingpersist()the right choice. No refactoring tomerge(), separatecreate()/update()methods, or renaming is necessary.Likely an incorrect or invalid review comment.

22-26: LGTM! Proper Jackson configuration.The

46-60: Proxy-aware equals/hashCode implementation looks correct.The implementation properly handles Hibernate proxies and uses identity-based equality with the persistence ID. The constant
hashCode()based on class identity is appropriate for JPA entities to maintain hash consistency across entity state transitions.src/main/java/org/example/entity/Album.java (1)
52-57: Factory method implementation is clean.The
fromDTOmethod properly validates required fields before construction and provides a clear error message. This is a good pattern for DTO-to-entity conversion.src/main/java/org/example/entity/Artist.java (1)
34-39: Factory method and entity structure look good.The
fromDTOmethod properly validates required fields. The entity structure with proxy-aware equals/hashCode is consistent with the other entities in this PR.src/main/java/org/example/entity/Song.java (1)
40-45: Factory method and entity structure are well implemented.The
fromDTOvalidation and construction pattern is consistent withAlbumandArtist. ThetoString()implementation is a nice addition for debugging.src/main/java/org/example/MyPod.java (1)

Remove Swedish comments and error messages for consistency.
The codebase uses English for code and comments elsewhere, but this file contains Swedish comments ("Kontrollera status", "Parse JSON") and error messages ("API-fel: "). This creates inconsistency and may confuse international contributors.

DisplaySong lacks equals/hashCode, breaking duplicate detection.
The contains() check on line 322 relies on Object.equals(), which compares by reference. Two DisplaySong objects with identical data will not be detected as duplicates, allowing the same song to be added multiple times to a playlist.

DisplaySong instances are compared by reference when using contains(), so
duplicate detection fails; implement DisplaySong.equals(Object) and hashCode()
to compare the meaningful fields (name, artist, album, time) so two DisplaySong
objects with identical data are considered equal; update the DisplaySong class
(constructor remains same) to override equals and hashCode using those fields
(null-safe) so contains() and any hashing collections behave correctly.

Implement the playlist repository methods.
All methods in this repository are stubs or return empty collections, rendering the entire playlist feature non-functional. Users won't be able to create, view, modify, or delete playlists.
This should be implemented with JPA-based persistence similar to the other repository implementations (e.g., AlbumRepositoryImpl, SongRepositoryImpl) using the EntityManagerFactory from PersistenceManager.
Do you want me to generate a complete implementation that follows the same patterns as the other repositories in this PR?
💡 Expected implementation pattern
The implementation should:
- Obtain
EntityManagerFactoryfromPersistenceManager - Use
emf.callInTransactionfor queries (findAll, findSongsInPlaylist) - Use
emf.runInTransactionfor modifications (create, delete, add/remove songs, rename) - Use JPQL queries to interact with the
Playlistentity - Handle the many-to-many relationship between Playlist and Song properly

8-44, PlaylistRepositoryImpl currently contains stubs; implement JPA-backed
logic using the PersistenceManager's EntityManagerFactory (emf) similar to
AlbumRepositoryImpl/SongRepositoryImpl: use emf.callInTransaction for read
methods findAll() and findSongsInPlaylist(Playlist) with JPQL queries against
the Playlist entity (e.g., "SELECT p FROM Playlist p" and fetching songs via
JOIN FETCH or retrieving playlist by id), and use emf.runInTransaction for
mutating methods createPlaylist(String), deletePlaylist(Playlist),
addSong(Playlist, Song), removeSong(Playlist, Song), and
renamePlaylist(Playlist, String) to persist/merge/remove entities and properly
manage the many-to-many association between Playlist and Song (update both sides
if necessary and merge the Playlist entity). Ensure you reference
PlaylistRepositoryImpl, PersistenceManager, emf.callInTransaction,
emf.runInTransaction, and the Playlist/Song entities in your changes.
