HQL查询

HQL的简单查询

	public static void demo() {
		Session session = HibernateUtils.getCurrentSession();
		Transaction trans = session.beginTransaction();
		
		//简单查询
		// sql中支持 * 的写法：select * from cst_customer; 但是在HQL中不支持* 的写法。
		/*
		Query query = session.craeteQuery("select * from Custome");
		报错 List<Customer> list = query.list();
		*/
		String sql = "from Customer";
		Query query = session.createQuery(sql);
		List<Customer> list  =query.list();
		
		for (Customer customer : list) {
			System.out.println(customer);
		}
		
		trans.commit();
