Hibernate foreign key of type String issue

Question

i am trying to connect two tables in a one to one mapping by declaring a first table column (of type String) as foreign key to the second table.

So here are my main two hibernate entities:

Primary entity StudyDetails:

@Entity
@Table(name="StudyDetails")
public class StudyDetails {

@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name="Id")
private Integer id;

@Column(name="InternalID", unique = true, nullable = false)
private String internalId;

@Column(name="StudyInstanceUID", unique = true)
private String studyInstanceUID;

@Column(name="LastUploadedDate")
@Type(type="org.jadira.usertype.dateandtime.joda.PersistentDateTime")
private DateTime lastUploadedDate; 

@Column(name="IsProcessed")
private boolean isProcessed;

@Column(name="IsUploaded")
private boolean isUploaded;

and the second one DicomSeriesMeta:

@Entity
@Table(name="DicomSeriesMeta")
public class DicomSeriesMeta {

@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name="Id")
private Integer id;

@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name="InternalID", referencedColumnName="InternalID")
private StudyDetails studyDetails;

public StudyDetails getStudyDetails() {
    return studyDetails;
}

public void setStudyDetails (StudyDetails studyDetails) {
    this.studyDetails = studyDetails;
}

@Column(name="PatientID")
private String patientID;

@Column(name="IssuerOfPatientID")
private String issuerOfPatientID;

@Column(name="PatientSex")
private String patientSex;

@Column(name="PatientName")
private String patientName;

@Column(name="PatientBirthDate")
private String patientBirthDate;
...
}

I would like to have StudyDetails.InternalID as foreign key to table DicomSeriesMeta ... It is a unique id of type String generated with a particular algorithm.

I am trying to save a DicomSeriesMeta object in database like:

....
DicomSeriesMeta dicomSeriesMeta = new DicomSeriesMeta();
dicomSeriesMeta.setPatientID(patientID);
dicomSeriesMeta.setIssuerOfPatientID(issuerOfPatientID);
dicomSeriesMeta.setPatientSex(patientSex);
dicomSeriesMeta.setPatientName(patientName);
dicomSeriesMeta.setPatientBirthDate(patientBirthDate);
dicomSeriesMeta.setOtherPatientIDs(otherPatientIDs);
....
dicomSeriesMeta.setStudyDetails(getStudyDetailsbyStudyId(studyInstanceUID));
Session s=HibernateUtil.openSession();
s.beginTransaction();
s.save(dicomSeriesMeta);
s.getTransaction().commit();
s.close();
....

However i am getting:

 Hibernate: insert into DicomSeriesMeta (AccessionNumber, InstitutionAddress, InstitutionName,    IssuerOfPatientID, MediaStorageSOPInstanceUID, OperatorsName, OtherPatientIDs, OtherPatientIDsSequence, PatientAge, PatientBirthDate, PatientID, PatientName, PatientSex, PhysiciansOfRecord, ReferringPhysicianName, RequestingPhysician, SOPInstanceUID, SeriesInstanceUID, StudyDate, InternalID, StudyID, StudyInstanceUID) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

I think you auto generate table by Hibernate entities. In this case you need to specify generate strategy. Select what you need: https://docs.oracle.com/javaee/5/api/javax/persistence/GenerationType.html
