获取有关 JPA 映射双轴的"java.lang.IllegalArgumentException"



我有一个简单的双向关系 Person <--> PersonHistory 实体，以下 JPA 实体具有包含审核变量和@Id变量的"可删除"类。

@Entity
@Table(name = "person")
public class Person extends Deletable {
@Column(name = "first_name", columnDefinition = "varchar(36)")
private String firstname;
@Column(name = "last_name", columnDefinition = "varchar(36)")
private String lastname;
@Column(name = "salary", columnDefinition = "DECIMAL(13,2)")
private BigDecimal salary;
@OneToMany(mappedBy = "person", targetEntity = PersonHistory.class, cascade = {CascadeType.ALL}, orphanRemoval = true)
private List<PersonHistory> personHistory;
}


@Entity
@Table(name="person_history")
public class PersonHistory extends Deletable{
@Column(name="company", columnDefinition = "varchar(36)")
private String company;
@Column(name="experience", columnDefinition = "tinyint")
private Integer experience;
@Id
@ManyToOne(targetEntity = Person.class,cascade= CascadeType.ALL)
@JoinColumn(foreignKey = @ForeignKey(name = "fk_person_history_person"), name = "person_id", referencedColumnName="id")
private Person person;

具有引用键关系的表结构：-

<!DOCTYPE html>

<title></title>

<body>
<table border="1" style="border-collapse:collapse">

</body>

但是收到错误说

此外，在依赖项之后，我正在使用

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-hikaricp</artifactId>
</dependency>
<!-- mariadb connector -->

可删除为：-

@MappedSuperclass
public class Deletable extends Auditable {
@Column(name = "deleted", columnDefinition = "tinyint")
private Integer deleted;
}


@EntityListeners(AuditingEntityListener.class)
@MappedSuperclass
public class Auditable extends Identifiable {
/**
* Created UNIX time
*/
@Column(name = "created_at", columnDefinition = "bigint", nullable = false)
@CreatedDate
private Long createdAt;
/**
* Last updated UNIX time
*/
@LastModifiedDate
@Column(name = "updated_at", columnDefinition = "bigint", nullable = false)
private Long updatedAt;
}


@MappedSuperclass
public class Identifiable implements Serializable {
/**
* Serializable identifier
*/
private static final long serialVersionUID = -5779695865916191496L;
/**
* The primary key of a table
*/
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
}

我错误地在"PersonHistory"类中的"Person"对象上添加了@Id，删除它后，工作完美。
