尝试使用Spring Data jpa使用DTO模式从两个数据库表中获取/读取数据时，如何解决错误“无法反序列化”？

问题描述

我正在尝试使用具有DTO模式的Spring Data Jpa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批注将两个表放入一个实体类。但是，当我尝试使用GET请求通过邮递员获取数据时，出现错误消息“无法序列化”。如果可以的话，请帮助我指明正确的方向，我整天都在工作，而且期限很短。预先感谢。

这是Postgresql表ERD：

以下是错误日志：

    @Column(name="receipt_number")
    private String receipt_number;

    @Column(name="consideration")
    private Double consideration;

    private Double rate;

    private Double amount_payable;

    private Double amount_paid;

    @ManyToOne
    @JoinColumn(name="user_profile_id",referencedColumnName = "id")
    private UserProfile userProfile;

    private State state;

    @Column(name="lga_id",table="deed_of_assignment")

    @Column(name="ward",table="deed_of_assignment")
    private Long ward;

    private String description_of_location;


    @OnetoOne
    @JoinColumn(name="author_stamp_duty_report_id",referencedColumnName = "id")
    private DeedOfAssignment deedOfAssignment;


}

这是我的DTO层

import com.oasis.firsbacklogbackend.entity.Lga;
import com.oasis.firsbacklogbackend.entity.State;
import lombok.Data;
import java.time.LocalDate;

@Data
public class AuditorStampDutyReportDto {

    private  Long id;

    private Long id_of_tax_payer_organization;

    private Long id_of_duty_payer_or_bank;

    private Long tin_of_tax_payer_organization;

    private String period_covered;

    private LocalDate date_of_transaction;

    private Long tin_of_duty_payer_or_bank;

    private String address_of_duty_payer_or_bank;

    private Long instrument_id;

    private Long assessment_number;

    private String receipt_number;

    private Double consideration;

    private Double rate;

    private Double amount_payable;

    private Double amount_paid;

    private Double balance;

    private Double penalty;

    private Double outstanding;

    private String remarks;

    private Long user_profile_id;

    private Long state_id;

    private Long lga_id;

    private Long ward;

    private String description_of_location;

    private Long author_stamp_duty_report_id;
}

这是我的服务层，在这里我使用逻辑来尝试从数据库表中获取数据

package com.oasis.firsbacklogbackend.services;



//relevant imports 


@Data
@Service
public class AuditorStampDutyReportService {

    private Logger logger = Logger.getLogger(AuditorStampDutyReportService.class.getName());

    @Autowired
    private AuditorStampDutyReportRepository auditorStampDutyReportRepository;


    @Autowired
    private UserProfileRepository userProfileRepository;

    public AuditorStampDutyReportDto entityToDto(AuditorStampDutyReport report) {

        AuditorStampDutyReportDto dto = new AuditorStampDutyReportDto();

        dto.setId(report.getId());
        Organization organization = report.getorganization();
        dto.setId_of_tax_payer_organization(organization.getId());
        dto.setTin_of_tax_payer_organization(report.getTin_of_tax_payer_organization());
        dto.setPeriod_covered(report.getPeriod_covered());
        dto.setDate_of_transaction(report.getDate_of_transaction());

        Banks banks= report.getBanks();
        dto.setId_of_duty_payer_or_bank(banks.getId());
        dto.setTin_of_duty_payer_or_bank(report.getTin_of_duty_payer_or_bank());
        dto.setAddress_of_duty_payer_or_bank(report.getAddress_of_duty_payer_or_bank());

        Instruments instruments = report.getInstruments();
        dto.setInstrument_id(instruments.getId());
        dto.setAssessment_number(report.getAssessment_number());
        dto.setReceipt_number(report.getReceipt_number());
        dto.setConsideration(report.getConsideration());
        dto.setRate(report.getRate());
        dto.setAmount_payable(report.getAmount_payable());
        dto.setAmount_paid(report.getAmount_paid());
        dto.setBalance(report.getBalance());
        dto.setPenalty(report.getPenalty());
        dto.setoutstanding(report.getoutstanding());
        dto.setRemarks(report.getRemarks());

        UserProfile userProfile =report.getUserProfile();
        dto.setUser_profile_id(userProfile.getId());

        State state = report.getState();
        dto.setState_id(state.getId());

        Lga lga = report.getLga();
        dto.setLga_id(lga.getId());

        dto.setWard(report.getWard());

        dto.setDescription_of_location(report.getDescription_of_location());

        DeedOfAssignment deedOfAssignment=report.getDeedOfAssignment();
        dto.setAuthor_stamp_duty_report_id(deedOfAssignment.getId());
        return dto;
    }

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
    public AuditorStampDutyReportRepository auditorStampDutyRepository;

    @GetMapping(path="/find/all")
    @ResponseBody
    public List<AuditorStampDutyReportDto> findAll(){
        List <AuditorStampDutyReport> findAll = auditorStampDutyRepository.findAll();
        return auditorStampDutyReportService.entityToDto(findAll);
    }

解决方法

您似乎在以下两个属性上缺少@ManyToOne注释，这些属性现在已按照堆栈跟踪的建议视为可序列化类型：

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

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

这些可能应该是

@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;
