spring JPA中的组合主键和外键

我有一个引用Doctor和Patient id的MedicalNote，并且有一个date属性，所有这些都构成了MedicalNote的主键。MedicalNote和Doctor和Patient都有一对多的双向关系。我想确定这是否是在Hibernate中实现的正确方法。
医疗笔记

package com.example.doctorkom.Entities;

import jakarta.persistence.*;
import lombok.*;

import java.sql.Date;

@Entity
@Table(name = "MedicalNote")
@IdClass(MedicalNoteId.class)
@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class MedicalNote {
    @Column(name = "Diagnosis")
    private String diagnosis;

    @Column(name = "Investigations")
    private String investigations;

    @Column(name = "Prescription")
    private String prescription;

    @Id
    @Column(name = "Date")
    private Date date;

    @Id
    @ManyToOne(cascade = {CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH, CascadeType.DETACH})
    @JoinColumn(name = "PatientId")
    private Patient patient;

    @Id
    @ManyToOne(cascade = {CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH, CascadeType.DETACH})
    @JoinColumn(name = "DoctorId")
    private Doctor doctor;
}

这种方法在用H2测试时会遇到一些麻烦，

据我所知，问题是您的测试在一个事务中运行，并且您为Parent和DoctormedicalNotes字段设置了cascade = CascadeType.ALL。因此deleteByDoctorId标记了MedicalNote实体以进行删除，但在事务结束时，Hibernate再次从doctor或parent传播持久状态。
如果您删除cascade = CascadeType.ALL或在“When”和“Then”的单独事务中运行“Given”测试块-测试将正确完成。
