在Hibernate中使用CriteriaBuilder連接表時出現問題

Question

我試圖使用元模型使用CriteriaBuilder加入表。 但是看來我做錯了。

//this is where is get and join tables
Root<Album> mainTable = criteria.from(Album.class); 
Join<Album, Track> tracksJoin = mainTable.join(Track_.album, JoinType.INNER); //type conflict

//piece of metamodel 1
@StaticMetamodel(Album.class)
public class Album_ {
public static volatile CollectionAttribute<Album, Track> tracksList;

//piece of metamodel 2
@StaticMetamodel(Track.class)
public class Track_ {
public static volatile SingularAttribute<Track, Album> album;

//piece of DAO Album

@ManyToMany
private ArrayList<Track> tracksList;

//piece of DAO Track

private Album album;

您能否解釋一下我在做什么錯以及如何加入這些表格。

Answer 1

嘗試一下，在類似的情況下，我的代碼可以解決。

Join<Album, Track> tracksJoin = mainTable.join(ALBUM_.tracksList, JoinType.INNER).join(Track_.album, JoinType.INNER);
