hql select 子查询的属性可封装成list、具体对象，改变默许的数组类型

hql select 子查询的属性可封装成list、具体对象，改变默认的数组类型
1，select子查询属性组成成list

    //把select选择的属性封装成list
    public void testHqlFindPropertyAsList(){
    	Configuration cfg = new Configuration().configure();
    	SessionFactory sessionFactory = cfg.buildSessionFactory();
    	Session session = sessionFactory.openSession();
    	Transaction ts = session.beginTransaction();
    	//注意查询属性的方式：使用 p.id  p.name  p.address
    	List persons = session.createQuery("select new List(p.id,p.name,p.address) from Person p where p.name like :myname ")
    			       .setString("myname", "%lijuan%").list();
    	for(Iterator it = persons.iterator(); it.hasNext();){
    		List eachList = (List)it.next();
    		for(Iterator it2 = eachList.iterator(); it2.hasNext();){
    			System.out.println();
    			System.out.println("***************************");
    			System.out.println(it2.next());
    			System.out.println("**************************");
    			System.out.println();
    		}
    	}
}

1，把select子查属性组装成新的对象

    //把select选择的属性封装成对象
    public void testHqlFindPropertyAsOjbect(){
    	Configuration cfg = new Configuration().configure();
    	SessionFactory sessionFactory = cfg.buildSessionFactory();
    	Session session = sessionFactory.openSession();
    	Transaction ts = session.beginTransaction();
    	
    	List smalPersonList = session.createQuery("select new SmalPerson(p.name,p.age) from Person p")
			       .setString("myname", "%lijuan%").list();
    	for(Iterator it = smalPersonList.iterator();it.hasNext();)
    	{
        	SmalPerson sp = (SmalPerson)it.next();
        	System.out.println(sp.getAge());
        	System.out.println(sp.getName());
        }
    }
