Ich habe über 20 Fragen zu Stackoverflow im Zusammenhang damit gelesen, aber keiner von ihnen hat funktioniert.Spring @Transactional aufrufen abstrakten Oberklasse-Methode wirft org.hibernate.HibernateException
Grundsätzlich habe ich eine Service-abstrakte Oberklasse mit 3 Methoden. Persist ist wie eine Schablonenmethode, während Speichern und Aktualisieren nur bei Bedarf überschrieben werden.
public abstract class BaseService<E> implements ServiceImpl{
protected E save(E object, Class<E> returnedClass){//save object}
protected E update(E object){//update object}
public boolean persist(E object) {
//validation rules
if(shouldSave) {
save(object);
}else {
update(object);
}
}
}
Dann habe ich diese Unterklasse
@Service
@Transactional
public CompanyService extends BaseService<Company> {
@Autowired
private CompanyRepository repository;
public void testSaving(Company company) {
repository.save(company);
}
@Override //from service impl
public CommpanyRepositoy getRepository() {
return repository;
}
}
und dies ist mein Einstiegspunkt
@RestController
@RequestMapping("/company")
public CompanyRestController {
@Autowired
private CompanyService service;
@RequestMapping(value = "/save", method = RequestMethod.POST)
public boolean save(@RequestBody Company company) {
return service.persist(company);
}
}
Nun ist die Sache, wenn ich für die testSaving Methode aufrufen, alles richtig geht. ABER, wenn ich die persist Methode rufe, gibt es immer den erwähnten Fehler. Ich habe viele Dinge ausprobiert, wie @Transactional in die BaseService Superklasse hinzufügen und sogar das Hinzufügen zu meinem Repository funktioniert nicht. Bitte, ich muss das reparieren, es macht mich verrückt. Irgendein Rat?
