hibernate in 查询

在hibernate 查询in 查询中不能使用testQuery1方法查询

public void testQuery1(){
        SessionFactory factory = null;
        Session session = null;
        factory = (SessionFactory) HibernateSessionFactory.getSessionFactory();
        session = factory.openSession();

        Integer id[] = new Integer[]{1,2,3,4};


        String hql = "from Group as p where p.id in (?)";
        Query query = session.createQuery(hql);
        query.setParameter(1, id);


        List list = query.list();
        System.out.println(list.size());
        session.close();
    }

应该使用如下方法：

public void testQuery2(){
        SessionFactory factory = null;
        Session session = null;
        factory = (SessionFactory) HibernateSessionFactory.getSessionFactory();
        session = factory.openSession();
        Integer id[] = new Integer[]{1,2,3,4};


        String hql = "from Group as p where p.id in (:test)";
        Query query = session.createQuery(hql);
        query.setParameterList("test", id);


        List list = query.list();
        System.out.println(list.size());
        session.close();
    }

[color=red]Integer id[] [/color]= new Integer[]{1,2,3,4};

String hql = "from Group as p where p.id in (:test)";

Query query = session.createQuery(hql);

query.[color=red]setParameterList[/color]("test", id);

两者的区别之处在蓝色字体部分。
