java - 对于 : 1, 类模型，找到了多个具有给定标识符的行 : com.。诊断

Question

下面是我的代码的模型、服务实现和错误跟踪。

模型类:

@Entity
@Table(name = "ph_diagnosis_history")
@JsonIdentityInfo(generator = ObjectIdGenerators.PropertyGenerator.class, property = "id",scope=Diagnosis.class)
public class Diagnosis extends AbstractEntity {
    @Column(name = "diagnosis_notes", length=255)
    @Length(max = 255, message = IprProp.MAX_LEN_255_MSG)
    private String diagnosisNote;

    @Enumerated(EnumType.STRING)
    private DiagnosisTypeEnum type;

    @Temporal(TemporalType.DATE)
    @Column(name = "diagnosis_date")
    @JsonSerialize(using = JsonDateSerializer.class)
    private Date diagnosisDate;

    @ManyToOne
    @JoinColumn(name = "patient_chart_id")
    private PatientChart patientChart;

    public String getDiagnosisNote() {
        return diagnosisNote;
    }

    public void setDiagnosisNote(String diagnosisNote) {
        this.diagnosisNote = diagnosisNote;
    }

    public DiagnosisTypeEnum getType() {
        return type;
    }

    public void setType(DiagnosisTypeEnum type) {
        this.type = type;
    }

    public Date getDiagnosisDate() {
        return diagnosisDate;
    }

    public void setDiagnosisDate(Date diagnosisDate) {
        this.diagnosisDate = diagnosisDate;
    }

    public PatientChart getPatientChart() {
        return patientChart;
    }

    public void setPatientChart(PatientChart patientChart) {
        this.patientChart = patientChart;
    }
}

我的服务:

public Diagnosis updateDiagnosis(IPRDTO clientDto, Long userId,
        Long patientChartId, DiagnosisDTO diagnosisDTO, Long diagnosisId) throws Exception {
    Diagnosis diagnosis = diagnosisRepository.findOne(diagnosisId);
    if (diagnosis!=null){
        if(diagnosis.getType().equals(DiagnosisTypeEnum.WORKING)){
            BeanCopyUtil.copyProperties(diagnosisDTO, diagnosis, true);
            return this.diagnosisRepository.saveAndFlush(diagnosis);
        }
        else{
            throw new BusinessException("updateDiagnosisValidation"); 
        }
    }
    throw new BusinessException("noDiagnosis"); 
}

我的堆栈跟踪:

尽管我的表现在有两行具有相同的 id，但我在这一行中收到了 HibernateException。

Diagnosis diagnosis = diagnosisRepository.findOne(diagnosisId);

请任何人帮助我解决我的错误。我的代码中可能存在什么错误。

Answer 1

嘿，这对我有用:

似乎我有两个选择:要么级联所有并删除一对一关系上的孤儿，要么在每次删除其与 Plate 的关系时显式调用我的存储库类来查找并保存原始工作表。我选择了第一个选择并将其添加到板类中:

@OneToOne(mappedBy = "plate", cascade = CascadeType.ALL, orphanRemoval = true)
