Using the Hibernate API directly in DAO implementations

java 代码

public class ProductDaoImpl extends HibernateDaoSupport implements ProductDao {

     public Collection loadProductsByCategory(String category) throws MyException {
        Session session = getSession(getSessionFactory(), false);
         try {
             List result = session.find(
                 "from test.Product product where product.category=?",
                 category, Hibernate.STRING);
             if (result == null) {
                 throw new MyException("invalid search result");
             }
             return result;
         }
         catch (HibernateException ex) {
             throw convertHibernateAccessException(ex);
         }
     }
}
