启动Spring Boot App时出现以下错误。我认为它与我的关系有关，从一个类到我的子类（ClientUser，MyUser）的公共子类（org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: default] Unable to build Hibernate SessionFactory

@MappedSuperclass
public abstract class IdentifiableEntity {
@Id
@NotNull
@GeneratedValue
@Column
private UUID id;

public IdentifiableEntity(UUID id) {
this.id = id;

这些是实体类。 映射的超类：
@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public class MyUser extends IdentifiableEntity {
@Column
private String name;
@Column
private String email;
@Column
private String phoneNumber;
@Column
private String password;
@Column
private Role role;
public MyUser() {
}
//getters and setters omitted
}
父类：
@Entity
public class Employee extends MyUser {
@Column
private String address;
@Column
private String image;
@OneToMany(mappedBy = "employee")
private List<Appointment> appointments;
public Employee() {
}
//getters and setters omitted
}
第一个孩子
@Entity
public class ClientUser extends MyUser {
@OneToMany(mappedBy = "clientUser")
private List<Appointment> appointments;
public ClientUser() {

//getters and setters omitted
}
第二个孩子
@Entity
public class Appointment extends IdentifiableEntity {
@ManyToOne
private Employee employee;
@ManyToOne
private ClientUser clientUser;
public Appointment() {

答案 0 :(得分：1)
可能是由hibernate 5.2.14中的错误引起的：hibernate.atlassian.net/browse/HHH-12332。升级到5.2.15或最新版本应修复它。
答案 1 :(得分：0)
我有同样的问题。我发现实体类中存在问题。我曾使用BigInteger进行版本控制。
@Version
private BigInteger version
我更改为Integer并解决了问题。
答案 2 :(得分：0)
我在自动生成的POJO类中的某个（相同名称）列上有一个@version批注。在我删除它之后，错误消失了。
e：与Ali的解决方案相似，但对我来说，它不是数据类型本身。
