休眠AttributeOverride註解錯誤

Question

我有以下實體：

public class MyEntity extends AuditableEntity { 
    @Column 
    private String name; 
} 

AuditableEntity類：

public class AuditableEntity { 
    @Id 
    @GenericGenerator(name = "uuid-gen", strategy = "uuid2") 
    @GeneratedValue(generator = "uuid-gen", strategy = GenerationType.IDENTITY) 
    private String id; 

    @CreatedBy 
    @JsonIgnore 
    @Embedded 
    @AttributeOverrides({ 
     @AttributeOverride(name = "user", column = @Column(name = "created_by_id")), 
     @AttributeOverride(name = "clientId", column = @Column(name = "created_by_client_id")) 
    }) 
    private AuditorDetails createdBy; 

    @LastModifiedBy 
    @JsonIgnore 
    @Embedded 
    @AttributeOverrides({ 
     @AttributeOverride(name = "user", column = @Column(name = "last_modified_by_id")), 
     @AttributeOverride(name = "clientId", column = @Column(name = "last_modified_by_client_id")) 
    }) 
    private AuditorDetails lastModifiedBy; 

} 

而且我AuditorDetails類：

@Embeddable 
public class AuditorDetails { 

    @Column(name = "auditor_client_id") 
    private String clientId; 

    @ManyToOne(fetch = FetchType.LAZY) 
    @JoinColumn 
    private User user; 
} 

另外，我有AuditorAware返回AuditorDetails對象。當我嘗試運行此，我有以下異常：

org.hibernate.MappingException：在映射重複列實體： com.aaa.MyEntity柱：USER_ID（應插入=「假」映射 更新=「假」）

但我不能讓該列（S）不能更新，而不是插入的。主要目標是在MyEntity有4列 - created_by_id,created_by_client_id,last_modified_by_id,last_modified_by_client_id，它將包含有關行修改和創建的所有數據。如何解決這個異常？

我已經修復了這個問題只是添加註釋AssociationOverrides：

@CreatedBy 
@JsonIgnore 
@Embedded 
@AssociationOverrides({ 
     @AssociationOverride(name = "user", joinColumns = @JoinColumn(name = "created_by_id")) 
}) 
@AttributeOverrides({ 
     @AttributeOverride(name = "user", column = @Column(name = "created_by_id")), 
     @AttributeOverride(name = "clientId", column = @Column(name = "created_by_client_id")) 
}) 
private AuditorDetails createdBy; 

@LastModifiedBy 
@JsonIgnore 
@Embedded 
@AssociationOverrides({ 
     @AssociationOverride(name = "user", joinColumns = @JoinColumn(name = "last_modified_by_id")) 
}) 
@AttributeOverrides({ 
     @AttributeOverride(name = "user", column = @Column(name = "last_modified_by_id")), 
     @AttributeOverride(name = "clientId", column = @Column(name = "last_modified_by_client_id")) 
}) 
private AuditorDetails lastModifiedBy;
