Envers＆“具有相同标识符值的不同对象已与会话相关联”

我试图在我的hibernate 5项目中使用envers以监视数据库中的更改。但我正面临着与@Embeddable元素有关的问题。Envers＆“具有相同标识符值的不同对象已与会话相关联”

当我保存包含@Embeddable元素的实体，我得到以下错误：Caused by: javax.persistence.EntityExistsException: A different object with the same identifier value was already associated with the session : [entity_embedded_entity_AUD#{SETORDINAL=1, REV=com.bl.dpi.appl[email protected]7a814310, AuditedEntityWithEmedded_id=d9b141ce-5ac1-4209-969e-8229845dd606, REVTYPE=ADD}]

我试过多的东西来解决这个（计算器FTW！），但没有更迭

这里是我的班

EmbeddableEntity.class

@Embeddable 
@AllArgsConstructor 
@NoArgsConstructor 
@ToString 
@Getter 
@Setter 
public class EmbeddableEntity { 
    @NotNull 
    @Column(name = "text") 
    private String text; 

    @NotNull 
    @Column(name = "value") 
    private Float value; 
}

AuditedEntityWithEmedded.class

@Entity 
@AllArgsConstructor 
@ToString 
@Getter 
@Setter 
@EqualsAndHashCode 
@Table(name = "AuditedEntityWithEmedded") 
@Audited 
public class AuditedEntityWithEmedded { 

    public AuditedEntityWithEmedded() { 
     this(UUID.randomUUID().toString()); 
    } 

    public AuditedEntityWithEmedded(String id) { 
     this.id = id; 
    } 

    @Id 
    @NotNull 
    private final String id; 

    @Column 
    private String nom; 

    @ElementCollection(targetClass = EmbeddableEntity.class) 
    @CollectionTable(name = "entity_embedded_entity", joinColumns = @JoinColumn(name = "AuditedEntityWithEmedded_id")) 
    private List<EmbeddableEntity> embeddedList; 
}

而我的测试类：AuditedEntityWithEmeddedTest.class

public class AuditedEntityWithEmeddedTest extends AbstractAuditedTest<AuditedEntityWithEmedded, String> { 

    @Autowired 
    private JpaRepository<AuditedEntityWithEmedded, String> repo; 

    private static final String nom10 = "1.0"; 

    private static final String TEXT0 = "Text0"; 
    private static final String TEXT1 = "Text1"; 
    private static final Float VAL0 = 0f; 
    private static final Float VAL1 = 1f; 

    @Test 
    public void saveEntity() { 
     AuditedEntityWithEmedded auditedEntityWithEmedded = new AuditedEntityWithEmedded(); 
     auditedEntityWithEmedded.setNom(nom10); 
     auditedEntityWithEmedded.setEmbeddedList(createEmbeddableList()); 

     repo.save(auditedEntityWithEmedded); 
    } 

    private List<EmbeddableEntity> createEmbeddableList() { 
     ArrayList<EmbeddableEntity> list = new ArrayList<EmbeddableEntity>(); 

     list.add(new EmbeddableEntity(TEXT0, VAL0)); 
     list.add(new EmbeddableEntity(TEXT1, VAL1)); 

     return list; 
    } 
}

当我运行测试类，我得到以下异常：

org.springframework.dao.DataIntegrityViolationException: A different object with the same identifier value was already associated with the session : [entity_embedded_entity_AUD#{SETORDINAL=1, REV=com.bl.dpi.appl[email protected]375084c9, AuditedEntityWithEmedded_id=d773bace-a59e-46ac-833a-53d8210f21bd, REVTYPE=ADD}]; nested exception is javax.persistence.EntityExistsException: A different object with the same identifier value was already associated with the session : [entity_embedded_entity_AUD#{SETORDINAL=1, REV=com.bl.dpi.appl[email protected]375084c9, AuditedEntityWithEmedded_id=d773bace-a59e-46ac-833a-53d8210f21bd, REVTYPE=ADD}]

是否有人有想法？（我已经测试并readed计算器上类似的帖子）

最后，加入@OrderColumn似乎解决异常

public class AuditedEntityWithEmedded { 

    public AuditedEntityWithEmedded() { 
     this(UUID.randomUUID().toString()); 
    } 

    public AuditedEntityWithEmedded(String id) { 
     this.id = id; 
    } 

    @Id 
    @NotNull 
    private final String id; 

    @Column 
    private String nom; 


    @ElementCollection(targetClass = EmbeddableEntity.class, fetch = FetchType.EAGER) 
    @JoinTable(name = "entity_embedded_entity", joinColumns = @JoinColumn(name = "AuditedEntityWithEmedded_id")) 
    @OrderColumn // <--- HERE 
    private List<EmbeddableEntity> embeddedList; 
}

更改'List'到'Set'，你不应该申请'@ OrderColumn'注解来解决这个问题。问题是，除非容器是'Set'类型，否则序数位置不会从我记得的位置被推入PK中。 – Naros
