使用@IdClass的額外列的JPA多對多在springTestContextPreparation中失敗Hibernate AnnotationException“沒有持久性id屬性”

Question

我試圖使用@IdClass注釋表示與某些實體的雙向關系，如下面的答案所示： https ： @IdClass

我有一個解決方案設置完全遵循鏈接的答案，應用程序運行正常。 我能夠使用我的所有CRUD端點，並且更改會反映在數據庫中。 但是，當我嘗試執行測試時， springTestContextPrepareTestInstance步驟失敗。

復合Id類

@Getter
@Setter
@EqualsAndHashCode
public class CompositeId implements Serializable {
    private static final long serialVersionUID = ...;

    @Type(type = "uuid-char")
    private UUID entity1;
    @Type(type = "uuid-char")
    private UUID entity2;
}

雙向實體類

@Entity
@Table(name = "bidirectional_entity")
@NoArgsConstructor
@Getter
@Setter
@IdClass(CompositeId.class)
public class BidirectionalEntity {
    @Id
    @ManyToOne
    @JoinColumn(name = "entity1_id", referencedColumnName = "id")
    private Entity1 entity1;

    @Id
    @ManyToOne
    @JoinColumn(name = "entity2_id", referencedColumnName = "id")
    private Entity2 entity2;
    ...
}

實體類

@Entity
@Table(name = "entity1")
@NoArgsConstructor
@AllArgsConstructor
@Getter
@Setter
@ToString
public class Entity1 {
    @Id
    @GenericGenerator(name = "uuid2", strategy = "uuid2")
    @GeneratedValue(generator = "uuid2")
    @Column(name = "id", updatable = false)
    @Type(type = "uuid-char")
    private UUID id;

    @OneToMany(mappedBy = "entity1",  orphanRemoval=true, cascade = CascadeType.ALL)
    @Setter(AccessLevel.NONE)
    private List<BidirectionalEntity> entities = new ArrayList<>();
    ...
}

@Entity
@Table(name = "entity2")
@NoArgsConstructor
@AllArgsConstructor
@Getter
@Setter
@ToString
public class Entity2 {
    @Id
    @GenericGenerator(name = "uuid2", strategy = "uuid2")
    @GeneratedValue(generator = "uuid2")
    @Column(name = "id", updatable = false)
    @Type(type = "uuid-char")
    private UUID id;

    @OneToMany(mappedBy = "entity2",  orphanRemoval=true, cascade = CascadeType.ALL)
    @Setter(AccessLevel.NONE)
    private List<BidirectionalEntity> entities = new ArrayList<>();
    ...
}

給出的錯誤是：

更新

在做了一些新手調試之后，在Hibernate Core（5.3.9） AnnotationBinder類 - > bindIdClass方法中，當執行測試設置時， componentId對象properties列表為空（顯然，它是檢查拋出錯誤的內容）。 但是，在正常運行程序時，有兩個屬性value org.hibernate.mapping.SimpleValue([org.hibernate.mapping.Column(entity*_id)]) ，其name entity *。 與BidirectionalEntity類匹配應該是。

Answer 1

我已經弄明白了這個問題。 除了我的服務測試，我還編寫了測試來驗證POJO上的約束驗證注釋。 我忘了將“Test”添加到CompositeId測試類名稱（ CompositeIdTest ）的末尾。 似乎在Spring測試上下文檢查中，測試類被Hibernate拉入並檢查了ID屬性。 一旦我更改了測試類名稱，測試開始運行正常。
