条件查询(Criteria Queries) 

@Test
    public void testCriteriaAnd(){
        List<User> users = session.createCriteria(User.class)
                .add(Restrictions.eq("name", "张三"))//相等
                .add(Restrictions.like("name", "王%"))//模糊查询：自己添加模糊通配符
                .add(Restrictions.like("name", "王", MatchMode.END))//模糊查询：MatchMode：END、START、ANYWHERE、EXACT
                .add(Restrictions.gt("age", 24))//大于
                .add(Restrictions.lt("age", 28))//小于
                .add(Restrictions.between("age", 24, 28))//介于两者之间
                .add(Restrictions.in("name", new String[]{"张三","李四"}))//包含
                .add(Restrictions.sqlRestriction("name = ‘张三‘"))//添加sql语句
                .add(Property.forName("name").in(new String[]{"张三","李四"}))//使用priperty查询
                .add(Restrictions.or(
                        Restrictions.eq("name", "张三"),
                        Restrictions.gt("age", 28)
                        ))//or连接
                .addOrder(Property.forName("age").asc())//排序
                .setFirstResult(0)//分页：起始条数
                .setMaxResults(2)//分页：显示几条
                .list();
        for(User u : users){
            System.out.println(u.getName()+"	"+u.getAge());
        }
    }
