そこで、Spring をトランザクション管理に使用しようとしています。最後に、私のアプリケーションは機能しましたが、削除してもコミットされません。Spring を使用する前は DAO でトランザクションを管理していましたが、後はこのコードを削除できると考えていました。しかし、今は削除しても DB にコミットしません。
私のDAO:
protected Session getSession() {
Session session = sessionFactory.openSession();
ThreadLocalSessionContext.bind(session);
return session;
}
public void delete(T t) {
Session session = getSession();
// **this approach I used before**
// session.beginTransaction();
// try {
// session.delete(t);
// session.getTransaction().commit();
// } catch (Exception e) {
// session.getTransaction().rollback();
// }
session.delete(t);
}
