ngqa中的写法是

	@Inject("java:$commons.dao()")
	private MongoDao dao;
	
	/**核心查询方法,通用查询*/
	public Pager<Student> query(QuestionQuery query) {
		if (query == null)
			query = new QuestionQuery();
		MCur cur = MCur.DESC("updatedAt");
		Pager<Student> pager = new Pager<Student>();
		pager.setCount(dao.count(Student.class, query.q));
		pager.setPage(query.page);
		pager.setPageSize(query.pageSize);
		if (query.skip() > 0)
			cur.skip(query.skip());
		if (query.limit() > 0)	
			cur.limit(query.limit());
		pager.setData(dao.find(Student.class, query.q, cur));
		return pager;
	}

现在最新版中这个怎么写呢 ？
