保存实体时，通过 @OneToMany 关系不会保存到它们的表中。我不明白怎么了。
员工：

@Entity
@Table(name = "EMPLOYEE", schema = PUBLIC)
public class Employee {

private String name;

private String lastname;

@OneToMany(mappedBy = "employee", cascade = CascadeType.ALL, orphanRemoval = true)
List<EmployeePhoneNumber> employeePhoneNumbers = new ArrayList<>();

}

员工姓名：

@Entity
@Table(name = "EMPLOYEE_PHONES", schema = PUBLIC)
public class EmployeePhoneNumber {

    @Id
    @SequenceGenerator(allocationSize = 1, name = "SEQ_EMPLOYEE_PHONES", schema = PUBLIC,
            sequenceName = "EMPLOYEE_PHONES_ID_SEQ")
    @GeneratedValue(generator = "SEQ_EMPLOYEE_PHONES", strategy = GenerationType.SEQUENCE)
    @Column(name = "ID", unique = true, nullable = false)
    private Long id;

    @ManyToOne
    @JoinColumn(name = "employee_id", referencedColumnName = "id",
            nullable = false, insertable = false, updatable = false)
    private Employee employee;

    @Column(name = "PHONE_NUMBER", unique = true, nullable = false)
    private String phoneNumber;

    @Enumerated(EnumType.STRING)
    @Column(name = "NUMBER_TYPE", nullable = false)
    private PhoneNumberType phoneNumberType;
}

如何设置这些字段并保存实体：

EmployeePhoneNumber workPhone = new EmployeePhoneNumber();
        workPhone.setPhoneNumber(workPhone);
        workPhone.setPhoneNumberType(PhoneNumberType.WORK_PHONE);

        EmployeePhoneNumber mobilePhone = new EmployeePhoneNumber();
        mobilePhone.setPhoneNumber(mobilePhone);
        mobilePhone.setPhoneNumberType(PhoneNumberType.MOBILE_PHONE);

        EmployeePhoneNumber corporatePhone = new EmployeePhoneNumber();
        corporatePhone.setPhoneNumber(corporatePhoneNumber);
        corporatePhone.setPhoneNumberType(PhoneNumberType.CORPORATE_PHONE);

        List<EmployeePhoneNumber> employeePhoneNumbers = employee.getEmployeePhoneNumbers();
        employeePhoneNumbers.add(workPhone);
        employeePhoneNumbers.add(mobilePhone);
        employeePhoneNumbers.add(corporatePhone);

        employee.setEmployeePhoneNumbers(employeePhoneNumbers);

        employeeRepository.save(employee);

方法完成后，我没有一个错误，一切都正常，只有表格没有填写-为什么？
