Unable to locate appropriate constructor on class

public List GetTop5NewsTitle(String type) {
		// TODO Auto-generated method stub
		Session session=HibernateSessionFactory.getSession();
		Query query=session.createQuery
		("select new TNews(id,title) from TNews t where t.type=:ttype order by t.createtime desc")
		.setString("ttype", type);
		query.setFirstResult(1);
		query.setMaxResults(5);
		List list=query.list();
		session.close();
		return list;
	}

/** default constructor */
	public TNews() {
	}

	/** minimal constructor */
	public TNews(Long id, String title, Integer type) {
		this.id = id;
		this.title = title;
		this.type = type;
	}

	/** full constructor */
	public TNews(Long id, String title, Integer type, String content,
			Date createtime, Long operid, Integer state) {
		this.id = id;
		this.title = title;
		this.type = type;
		this.content = content;
		this.createtime = createtime;
		this.operid = operid;
		this.state = state;
	}

实体对象中不存在只有两个属性的构造器;并且属性个数相同但顺序不同也会出现这种错误

假如写成：

TNews(id,title,type2)

回报java.lang.NullPointerException

正确写法

public List GetTop5NewsTitle(String type) {
		// TODO Auto-generated method stub
		Session session=HibernateSessionFactory.getSession();
		Query query=session.createQuery
		("select new TNews(id,title,type) from TNews t where t.type=:ttype order by t.createtime desc")
		.setString("ttype", type);
		query.setFirstResult(1);
		query.setMaxResults(5);
		List list=query.list();
		session.close();
		return list;
	}
