JPA CriteriaQuery ManyToMany Predicate - spring-boot

Question

A many-to-many relationship exists between songs and artists like this:
public class Song {
// ... other fields here
protected Collection<Artist> artists;
#JoinTable(
name = "song_artists",
schema = "playout",
joinColumns = #JoinColumn(name = "song"),
inverseJoinColumns = #JoinColumn(name = "artist"),
foreignKey = #ForeignKey(name = "fk_song_artists_song"),
inverseForeignKey = #ForeignKey(name = "fk_audio_artists_artist")
)
#ManyToMany
public Collection<Artist> getArtists(){
return artists;
}
}
The artist class is a basic Entity
public class Artist {
}
Given a Song x, show songs by any of the artists involved in Song x
, A raw SQL query would be something like this
SELECT * FROM songs WHERE id IN((SELECT song FROM song_artists x WHERE x.artist = ?));
Where '?' would be replaced by a comma separated string of artist IDs involved in the song in question
How can the same result be achieved with JPA (using Hibernate specifically)
Song song = null; // get desired song
Collection<Artist> artists = song.getArtists();
CriteriaBuilder builder = entityManager.getCriteriaBuilder()
CriteriaQuery criteria = builder.createQuery(Song.class);
Root<Song> root = criteria.from(Song.class);
Subquery<Artist> subquery = null; // how to create an appropriate subquery from the join
How can we filter the results here (get more songs by any of the artists in "artists" collection)?
Your feedback will be very much appreciated

Answer 1

Solved it!
In case you face something similar, here's what I did:
Subquery<Artist> subquery = criteria.subquery(Artist.class);
subquery.from(Artist.class);
Join<Audio, Artist> join = subquery.correlate(root.join("artists", JoinType.LEFT));
subquery.select(builder.nullLiteral(Artist.class));
subquery.where(join.in(value.getArtists()));
criteria.select(root).where(
builder.and(
builder.notEqual(root, value), builder.exists(subquery)
)
);
