// 1.简单查询

List<Customer> list = session.createCriteria(Customer.class).list();

// 2.条件查询:

Criteria criteria = session.createCriteria(Customer.class);

criteria.add(Restrictions.eq("name","芙蓉"));

List<Customer> list = criteria.list();

// 3.分页查询:

Criteria criteria = session.createCriteria(Customer.class);

criteria.setFirstResult(3);

criteria.setMaxResults(3);

List<Customer> list = criteria.list();
