User エンティティとその更新を更新しようとしています:
以下のコードを参照してください: Hibernate Mapping File:

UserDAOImpl.java
public class UserDaoImpl implements UserDao {
@Override
public boolean update(User t) throws SQLException {
boolean status;
try{
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction tx = session.beginTransaction();
session.saveOrUpdate(t);
session.flush();
session.refresh(t);
tx.commit();
session.close();
status = true;
}catch (HibernateException e) {
e.printStackTrace();
status=false;
}
return status;
}
--------
}
Junit -テスト:
@Test
public void testUpdate() throws SQLException {
presenter1.setName("PREE");
boolean status = userDao.update(presenter1);
List<User> users = userDao.searchMatching(presenter1);
String name = users.get(0).getName();
assertEquals(name, "PREE");
}
セットアップでは、次のように presenter1 を作成しています。
// Create user
presenter1 = new User(PRESENTER1, PASSWORD, PRESENTER_NAME1);
//session.saveOrUpdate(presenter1);
userDao.create(presenter1);
エンティティを更新しない理由を教えてください。
