示例2: loadSequentialRowsForward
import java.sql.ResultSet; //導入方法依賴的package包/類

* Loads a single logical row from the result set moving forward. This is the
* processing used from the ScrollableResults where there were collection fetches

* @param resultSet The result set from which to do the load.
* @param session The session from which the request originated.
* @param queryParameters The query parameters specified by the user.
* @param returnProxies Should proxies be generated
* @return The loaded "row".
* @throws HibernateException
