This is a tough one. I know there is plenty of questions like that here, but my problem is, that I'm not allowed to change/edit the class heirarchy, because this is an already productive application, which if changed fundamentally, must be tested thoroughly and this will cost to much. Even if there's something stupid in the hierarchy, I'm not allowed to change it, because the whole application might stop functioning, and it will take long hours to bring it back on. (Nasty, I know). So, basically, what I am looking for here is some kind of workaround, that will give me a chance to delete entity instances without constraint violation and changing the hierarchy.
On top of the hieararchy is an entity "Request", that splits further in "Import Request" and "Export Request". So ImportRequest extends Request and ExportRequest extends Request. Every ExportRequest has a Set of Position, which is defined like that:
@OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
@JoinColumn(name = "antrag_id")
@ForeignKey(name= "FK_EXPAN_POS")
public Set<Position> getPosition() {
try {
position.size();
} catch (Exception e) {
// NO Need just make hibernate load the list
}
return position;
}
Position is just another Entity. And every ImportRequest has a Set of ImportPosition, like that:
@OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
@JoinColumn(name = "antrag_id")
@ForeignKey(name= "FK_IMPAN_POS")
public Set<ImportPosition> getImportPosition() {
try {
importPosition.size();
}
catch (Exception e)
{
// hallo
}
return importPosition;
}
whereas ImportPosition extends Position.
Every Position has only one Probe assigned to it, which is defined like that:
@OneToOne(cascade = CascadeType.ALL)
@JoinColumn(name = "probe")
@ForeignKey(name = "FK_POS_PROB")
public Probe getProbe() {
return probe;
}
Implicitly evert ImportPosition will have one too, because it extends the Position. Which also works on a database level.
I'm deleting an IMportRequets with a method like this:
@Transactional
public void cleanArchivedRequests() {
List<Integer> archivedRequestList = requestDao.retrieveAllArchivedRequests();
for (Integer antragId : archivedRequestList) {
Request requestToDelete = requestDao.loadById(requestId);
requestDao.delete(requestToDelete);
StringBuffer protocolEntry = new StringBuffer("Request mit der ID: ");
protocolEntry.append(requestId);
protocolEntry.append(" gelöscht!");
protocol(protocolEntry.toString());
}
}
Apparently Hibernate has problems deleting the Probe which is referenced by an ImportPosition in an ImportRequet, because I get this:
[java] java.sql.BatchUpdateException: Cannot delete or update a parent row: a foreign key constraint fails (`position`, CONSTRAINT `FK_POS_PROB` FOREIGN KEY (`probe`) REFERENCES `probe` (`id`))
requestDao is injected via Spring with applicationContext-daos.xml in my class, where the method "cleanArchivedRequests" is.
So my question is, given that hierarchy, is it possible at all to successfully delete the Probe instances from the ImportPosition and if so, how would that work. I've already tried to delete the Probe instances first and than the ImportRequest, but that didn't work, supposedly because the whole thing happens in one transaction. Or at least this is my explanation.
PS. The whole Stacktrace goes like this:
[java] java.sql.BatchUpdateException: Cannot delete or update a parent row: a foreign key constraint fails (`position`, CONSTRAINT `FK_POS_PROB` FOREIGN KEY (`probe`) REFERENCES `probe` (`id`))
