大侠们出手吧
一段代码
================
/*
* 查询对象
*/
public void testQuery()
{
Session session=null;
Transaction tx=null;
try
{
session=HibernateUtils.getSession();
tx=session.getTransaction();
tx.begin();
Query query=session.createSQLQuery("from customer");
List<Customer> list=query.list();
for(Iterator<Customer> iterator=list.iterator();iterator.hasNext();)
{
Customer customer=(Customer)iterator.next();
System.out.println(customer.getPassword());
}
tx.commit();
}catch(Exception e)
{
e.printStackTrace();
}
}
=============================
提示错误如下:
