Question

我正在尝试实现用户详细信息服务以包含实体的审核数据。

UserEntity类如下：

@Data
@Entity
@Audited
public class UserEntity {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;

    @Column(unique = true,updatable = false)
    private String uuid;

    private String username;

    private String firstName;

    private String lastName;
}

我还有以下类，其中包含审计元数据。该课程将由其他实体进行扩展。

@Data
@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
@Audited
public class Auditable {

    @CreatedDate
    private Long createdDate;

    @LastModifiedDate
    private Long lastModifiedDate;

    @CreatedBy
    private UserEntity createdBy;

    @LastModifiedBy
    private UserEntity modifiedBy;

}

这是我的用户详细信息服务。

@Configuration
@EnableJpaAuditing
public class SpringSecurityAuditorAware implements AuditorAware<UserEntity> {

    @Autowired
    private AccessToken accessToken;

    @Autowired
    private UserEntityRepository userRepo;

    @Override
    public UserEntity getCurrentAuditor() {

        UserEntity user = userRepo.findByUuid(accessToken.getSubject());
        return user;
    }

}

现在，当我运行代码时，我收到以下错误消息。

如果删除UserEntity字段，一切正常，审核数据createdDate和lastModifiedDate会正确记录在数据库中。

我还为UserEntity字段添加了@ManyToOne注释，代码运行正常，但数据库没有字段createdBy和modifiedBy。我该如何解决这个问题？

我们应该有一个名为Auditable_aud的表。
