Question

我有以下实体：

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

AuditableEntity上课：

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;

}

我的AuditorDetails课程：

@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个对象。当我尝试运行它时，我有以下异常：

org.hibernate.MappingException：实体映射中的重复列： com.aaa.MyEntity列：user_id（应使用insert =＆＃34; false＆＃34; 更新=＆＃34;假＆＃34）

但我不能使这个列不可更新且不可插入。主要目标是拥有MyEntity 4列 - created_by_id，created_by_client_id，last_modified_by_id，last_modified_by_client_id，其中包含有关行修改和创建的所有数据。如何解决这个异常？

我已修复此问题，只需添加注释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;

Hibernate AttributeOverride注释错误
