2-account_entity:
3-人:
4-employee_company:
ENTITIES:
1-MedicalCompany:
@SuppressWarnings("serial")
@Entity
@Table(name = "medical_company")
public class MedicalCompany implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "id", unique = true, nullable = false)
@Basic(fetch = FetchType.EAGER)
private Long id;
@OneToOne
@Cascade(value = { CascadeType.ALL })
@JoinColumn(name = "medical_company_id", referencedColumnName = "account_entity_id")
private AccountEntity accountEntity;
}
2-AccountEntity:
@SuppressWarnings("serial")
@Entity
@Table(name = "account_entity")
public class AccountEntity implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "account_entity_id", unique = true, nullable = false)
@Basic(fetch = FetchType.EAGER)
private Long id;
}
3-人:
@SuppressWarnings("serial")
@Entity

@ManyToOne
private Person person;
@ManyToOne
private MedicalCompany medicalCompany;
@Size(max = 150, message = "{long.value}")
@Column(name = "title_text", length = 150, nullable = true)
private String titleText;
@Column(name = "employee_manager")
private long employeeManager;
}
5-EmployeeCompany:
@SuppressWarnings("serial")

@AssociationOverrides(value = {
@AssociationOverride(name = "pk.medicalCompany", joinColumns = @JoinColumn(referencedColumnName = "medical_company_id")),
@AssociationOverride(name = "pk.person", joinColumns = @JoinColumn(referencedColumnName = "person_id")),
@AssociationOverride(name = "pk.titleText"),
@AssociationOverride(name = "pk.employeeManager") })
public class EmployeeCompany implements Serializable {
@EmbeddedId
private EmployeeCompanyId pk = new EmployeeCompanyId();
@Transient
public void setEmployeeManager(long employeeManager) {
this.pk.setEmployeeManager(employeeManager);
}
public long getEmployeeManager() {
return pk.getEmployeeManager();
}
@Transient
public void setTitleText(String titleText) {

}
public void setMedicalCompany(MedicalCompany medicalCompany) {
this.pk.setMedicalCompany(medicalCompany);
}
@Transient
public MedicalCompany getMedicalCompany() {
return this.pk.getMedicalCompany();
}
public void setPk(EmployeeCompanyId pk) {
this.pk = pk;
}
public EmployeeCompanyId getPk() {
return pk;
}
}
アプリケーションを実行しようとすると、次のエラーが発生します。

このエラーが発生する理由と解決方法を教えてください。
このエラーは、medical_company_idと呼ばれるmedical_companyテーブルに列がないことを示しています。 medical_companyの列は、単にidと呼ばれます。
AccountEntityの主キーフィールドに名前を付けているので、MedicalCompanyのreferencesColumnName属性を削除します。非主キーフィールドを参照する場合にのみ必要だと思います。
@JoinColumn(name = "medical_company_id", referencedColumnName = "account_entity_id")
