Fetch returns only one item in collection - mysql

Question

Table info:
The Image table contain a foreign key mediaid for its the parent table Media
----------
id | mediaid | url
========================
104 | 103 | IMG_PATH
383 | 103 | IMG_PATH
384 | 103 | IMG_PATH
395 | 103 | img_path
The Media entity holds a collection of Images :
private Set<Image> images = new HashSet<Image>(0)`;
#OneToMany(mappedBy = "media", targetEntity = Image.class ,cascade = CascadeType.ALL)
public Set<Image> getImages() {
return images;
}
Image entity snippet:
private Media media;
#ManyToOne
#JoinColumn(name = "mediaId")
public Media getMedia() {
return media;
}
I implemented the following query, that should return a Media object with a collection of all images whose fk matches its id provided.
CriteriaBuilder cb = em.getCriteriaBuilder();
CriteriaQuery<Media> cqObject = cb.createQuery(Media.class);
Root<Media> rootEntry = cqObject.from(Media.class);
rootEntry.fetch(Media_.images, JoinType.LEFT);
Predicate predicate = cb.equal(rootEntry.get(Media_.id), id);
cqObject.select(rootEntry).where(predicate);
Media _fetcheMedia = em.createQuery(cqObject).getSingleResult();
The collection for the Media object returned only ever contains one image item. I know for certain that database contains multiple Image items for the specified Media.
*Note Media_ is simply a metamodel class that represents the Media entity
Hibernate out for Media object with id=103
select media0_.mediaId as mediaId1_8_0_,
images1_.imageId as imageId1_6_1_,
media0_.active as active2_8_0_,
media0_.created as created3_8_0_,
media0_.description as descript4_8_0_,
media0_.listType as listType5_8_0_,
media0_.parentId as parentId6_8_0_,
media0_.propertyTypeId as property7_8_0_,
media0_.seasonId as seasonId8_8_0_,
media0_.status as status9_8_0_,
media0_.userId as userId10_8_0_,
images1_.active as active2_6_1_,
images1_.created as created3_6_1_,
images1_.imageTypeId as imageTyp5_6_1_,
images1_.imageUrl as imageUrl4_6_1_,
images1_.mediaId as mediaId6_6_1_,
images1_.mediaId as mediaId6_6_0__,
images1_.imageId as imageId1_6_0__ from media media0_
left outer join image images1_ on media0_.mediaId=images1_.mediaId where media0_.mediaId=103

Answer 1

It was a silly mistake on my part, I forgot to override the hashcode and equals method for the Image entity . Added them and it know works as it should.
#Override
public int hashCode() {
final int prime = 31;
int result = super.hashCode();
result = prime * result + (int) (id ^ (id >>> 32));
return result;
}
#Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (!super.equals(obj))
return false;
if (getClass() != obj.getClass())
return false;
Image other = (Image) obj;
if (id != other.id)
return false;
return true;
}
