Я думаю, что может быть проблема с сеансом.Сессия может быть автоматически закрыта при необходимости открытия.
Мой тестовый класс
@Test
public void testUpdateBookOrdersShippingAddress() {
Integer orderId = 48;
BookOrders bookorders = ordersDAO.get(orderId);
System.out.println("Update Before (ShippingAddress) : " + bookorders.getShippingAddress());
bookorders.setShippingAddress("New Home Shipping Address");
try {
ordersDAO.update(bookorders);
} catch (Exception e) {
e.printStackTrace();
}
BookOrders updatedOrder = ordersDAO.get(orderId);
System.out.println("Update After (ShippingAddress) : " + updatedOrder.getShippingAddress() );
assertEquals(bookorders.getShippingAddress(), updatedOrder.getShippingAddress());
}
Hibernate Класс для метода get и update.
public T update(T t) {
Session session = sessionFactory.openSession();
Transaction transaction = null;
try {
transaction = session.beginTransaction();
session.merge(t);
session.flush();
session.getTransaction().commit();
session.close();
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
transaction.rollback();
}
return t;
}
public T get(Class<T> type,Object id) {
Session session = sessionFactory.openSession();
Transaction transaction = null;
T t = null;
try {
transaction = session.beginTransaction();
t = session.get(type, (int)id);
session.flush();
session.getTransaction().commit();
session.close();
}catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
transaction.rollback();
}
return t;
}
