hibernate分页查询的各种方法

统计总数：

	public Integer countAll1() {
		 
			String hql = "select count(*) from News as news";
			List list = getHibernateTemplate().find(hql);
			return list.get(0).hashCode(); 
	}
	
	public Integer countAll2() {
		 
		Criteria  criteria = this.getSession().createCriteria(News.class);
		return ((Integer) (criteria.setProjection(Projections.rowCount())).uniqueResult()).intValue();
}

分页查询：

	public List pagerList(Integer beginNum,Integer maxNum){
		DetachedCriteria dCriteria = DetachedCriteria.forClass(News.class);
		List list = getHibernateTemplate().findByCriteria(dCriteria, beginNum, maxNum);
		return list;
	}

	public List pagerList1(String news,Integer beginNum,Integer maxNum){
		Criteria criteria = this.getSession().createCriteria(News.class);
		criteria.setFirstResult(beginNum);
		criteria.setMaxResults(maxNum);
		return criteria.list();
	}
	
	public List pagerList2(String news,Integer beginNum,Integer maxNum){
		String hql = "from News";
		Query query = this.getSession().createQuery(hql);
		query.setFirstResult(beginNum);
		query.setMaxResults(maxNum);
		return query.list();
	}
