Question

I have a problem with sessionFactory in Spring.

public abstract class GenericDao<T,PK extends Serializable>
extends HibernateDaoSupport 
implements IGenericDao<T, Serializable> {

private Class<T> persistentClass;

public Class<T> getPersistentClass() {
    return persistentClass;
}

public void setPersistentClass(Class<T> persistentClass) {
    this.persistentClass = persistentClass;
}

---

@Repository
@Transactional
public class CategoryDao extends GenericDao<Category, Long> {
@Autowired
private SessionFactory sessionFactory;
public CategoryDao() {
    setPersistentClass(Category.class);
    setSessionFactory(sessionFactory);

}

---

And My sessionFactoryBean defined in appContext.xml file.

Answer 1

@Autowired works after object is constructed, thus you cannot use its result in a constructor.

You can use this approach to autowire SessionFactory into HibernateDaoSupport.
