spring-data-jpa 异常错误：一对多双向父表的关键字条目重复

我是jpa的新手。我遇到了一个关于两个表之间的关系的问题。这个关系是一对多的双向关系。enter image description here
我有两个实体。具有和ID自动生成的约会（子项）

@Entity
@Table(name="appointment")
public class Appointment {  
@Id 
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;

@Column(name="phone")
private long phone; 
@Column(name="name_patient")
private String name;

@Column(name="hour_appointment")
private LocalTime hourAppointment;

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

@ManyToOne(targetEntity = AppointmentDate.class,cascade = CascadeType.ALL)
private AppointmentDate appointmentDate; 

//getters and setters 
//empty constructor and constructor with all arguments except id because it is autogenerated }

然后我有一个表，到目前为止，它有一个唯一的列，这是PK（在未来，它计划添加更多的列到这个表）

@Entity
@Table(name="appointment_date")
public class AppointmentDate {

@Id
private LocalDate date;

@OneToMany(mappedBy = "appointmentDate")
private List<Appointment> appointments;

//getters and setters 
//empty constructor and constructor with the unique argument }

我需要这种双向关系，因为每当后端获得PUT请求时，它会收到一个Appointment JSON，然后如果父表中没有约会的日期（FK），Hibernate会自动创建它，如果日期已经存在，那么它只需要添加新的行，其中包含具有相同的和以前创建的FK的新约会实体数据。
因此，当我通过PUT方法一个接一个地发送这两个JSON时：

{
"phone": "12345",
"name":"Anabel",
"hourAppointment":"09:30",
"description" : "She is sick",
"appointmentDate": {
    "date": "2023-01-01"
}}

第二个JSON

{
"phone": "54321",
"name":"Michael",
"hourAppointment":"10:30",
"description" : "Broken Arms",
"appointmentDate": {
    "date": "2023-01-01"
}}

我得到了以下异常

这没有任何意义，因为它是多对一关系，它应该根据需要接受具有相同FK的任意多个实体。
这是application.propertiesmysql容器的www.example.com

spring.datasource.url=jdbc:mysql://localhost:13306/consultorioDB?useSSL=false
spring.datasource.username=root
spring.datasource.password=***

spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect 
spring.jpa.hibernate.ddl-auto=update

我想是因为约会实体中ID自动生成的原因，但我确实需要自动生成ID，并有一个AppointmentDate的PK需要手工设置。
任何想法？请任何澄清需要，请随时评论。这是我在stackoverflow的第一个问题。谢谢和干杯。

  1. AppointmentDate作为一个单独的类看起来很奇怪
    1.您有@Id私人LocalDate日期;所以它必须是唯一的。这就是为什么你有重复的键
    1.解决方案是重新设计数据库。也许，将LocalDate日期存储在Appointment类中就可以了
