EDIT: Added parts for album definition:

@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
public Long id;
@Column(length = 254)
@Constraints.MaxLength(254)
@NotNull
public String name;
@Column(name = "fullname", length = 254)
@Constraints.MaxLength(254)
@NotNull
public String fullName;
public Integer year;
@ManyToOne
@JoinColumn(name = "artist")
public Artist artist;
@OneToMany(fetch = FetchType.EAGER, mappedBy = "album")
@OrderBy("name asc")
public List<Song> songs = Lists.newArrayList();
@OneToMany(fetch = FetchType.EAGER, mappedBy = "originalAlbum")
@OrderBy("name asc")
public List<Song> covers = Lists.newArrayList();

I looked at EntityNotFoundException: Bean was deleted - lazy loading failed

Somewhere there must be some kind of corrupted data. However, since the models I'm working with are quite complex, I am losing the beginning to start debugging.

Any tips? (Play Framework 2.3, Avaje Ebean 3.1.1) Upgrading to version 2.4 Framework is still the same issue.

Answer 1

Here is what I use to find the root cause of ORM problems:

• (), (-);
• (), (), ;
• ORM- (-);
• ; ,
• , ORM .

:

• , Album (.. );
• Album ;
• , , ​​ ORM EBean.
• , SQL; ,
• , .
