Hibernate “如何解决错误”；无法反序列化“；当尝试使用SpringDataJPA使用DTO模式从两个数据库表获取/读取数据时？

我正在尝试使用SpringDataJPA和DTO模式从5个表中读取数据，这些表与Springboot共享数据库中的关系。我使用@Table和@SecondaryTable注释将两个表放在一个实体类中。然而，当我尝试使用GET请求与postman一起获取数据时，我得到一个错误，上面写着“无法序列化”。如果可以的话，请帮我指出正确的方向，我一整天都在做这件事，我的最后期限很短。提前谢谢

以下是postgresql表ERD：

以下是错误日志：

这是我下面的控制器层

//relevant imports

@RestController
@RequestMapping("api/auditors_report")
public class AuditorStampDutyReportController {

    @Autowired
    public AuditorStampDutyReportService auditorStampDutyReportService;

    @Autowired

    @GetMapping(path="/find/all")
    @ResponseBody

        List <AuditorStampDutyReport> findAll = auditorStampDutyRepository.findAll();
        return auditorStampDutyReportService.entityToDto(findAll);

您似乎缺少以下两个属性的

@ManyToOne

注释，这两个属性现在被视为堆栈跟踪所建议的可序列化类型：

@Column(name="state_id", table="deed_of_assignment")
private State state;

@Column(name="lga_id", table="deed_of_assignment")
private Lga lga;

这些可能是

@ManyToOne(fetch = LAZY)
@JoinColumn(name="state_id", table="deed_of_assignment")
private State state;

@ManyToOne(fetch = LAZY)
@JoinColumn(name="lga_id", table="deed_of_assignment")
private Lga lga;

@ManyToOne(fetch = LAZY)
@JoinColumn(name="state_id", table="deed_of_assignment")
private State state;

@ManyToOne(fetch = LAZY)
@JoinColumn(name="lga_id", table="deed_of_assignment")
private Lga lga;
