org.hibernate.MappingException：无法找到具有逻辑名称的列

Question

您好我的表格如下：

1- medical_company ：

• account_entity* 表 account_entity_id 列上的medical_company_id 外键 （不是pk） ***
• 第1栏
• 专栏2
• 第三栏

2- account_entity ：

• account_entity_id （pk）
• 第1栏
• 专栏2
• 第三栏

3 人同行：

• person_id （pk）
• 第1栏
• 专栏2
• 第三栏

4- employee_company：

• 在COMPANY_ID外键 medical_company 上表 medical_company_id
• employee_id person_id* 上 人员 表上的外键 *
• 第1栏
• 专栏2

实体：

1- 医疗公司：

@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")

    @Basic(fetch = FetchType.EAGER)
    private Long id;

}

3 人同行

 @SuppressWarnings("serial")
@Entity
@Table(name = "person")
public class Person implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    @Column(name = "person_id", unique = true, nullable = false)
    @Basic(fetch = FetchType.EAGER)
    private Long id;

}

4- EmployeeCompanyId ：

@SuppressWarnings("serial")
@Embeddable
public class EmployeeCompanyId implements Serializable {

    @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- 员工公司：

@SuppressWarnings("serial")
@Entity
@Table(name = "employee_company")
@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) {
        this.pk.setTitleText(titleText);
    }

    public String getTitleText() {
        return pk.getTitleText();
    }

    public void setPerson(Person person) {
        this.pk.setPerson(person);
    }

    @Transient
    public Person getPerson() {
        return this.pk.getPerson();
    }

    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;
    }

}

尝试运行应用程序时，出现以下错误：

请告知为什么我收到此错误，以及如何解决它。

Answer 1

此错误告诉您在medical_company表上没有名为medical_company_id的列。medical_company上的列仅称为id。
