私は Hibernate マッピングの問題に直面しています: ID ジェネレーターを解釈できませんでした 戦略: スタック トレース:
Exception in thread "SpringOsgiExtenderThread-14" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactoryMTS' defined in OSGi resource[classpath:spring-beans.xml|bnd.id=288|bnd.sym=persistence]: Invocation of init method failed; nested exception is org.hibernate.MappingException: could not instantiate id generator [entity-name=com.db.model.UserProfiles]

私のCustome IDジェネレータークラスは次のようになります:
public class UserProfileCustomIDGenerator extends IdentityGenerator{
@Override
public Serializable generate(SessionImplementor session, Object object)
throws HibernateException {
// TODO Auto-generated method stub
UserProfiles userProfile = (UserProfiles)object;
if(userProfile.getId() != 0){
return userProfile.getId();
}else{
Serializable id = super.generate(session, object);
return id;
}
}
}
私はグーグルで検索しましたが、解決策を得ることができません。私が行った間違いや解決策があれば教えてください。ありがとう。
