Hibernate分页的两种实现方法

public Page getPage(int currentPage,int pageSize,Criterion...crts){Criteria c=session.createCriteria(House.class);List list=null;for (int i = 0; i < crts.length; i++) {c.add(crts[i]);}c.setProjection(Projections.rowCount());int totalRecord=Integer.valueOf(c.uniqueResult().toString());c.setProjection(null);c.setFirstResult((pageSize)*(currentPage-1));c.setMaxResults(pageSize);list=c.list();Page page=new Page();page.setCurrentPage(currentPage);page.setPageSize(pageSize);page.setTotalRecord(totalRecord);page.setList(list);return page;}

public Page getPage(int currentPage,int pageSize,String hql,Object...args){String countHql="select count(*) "+hql.substring(hql.indexOf("from"));Session session=HibernateUtil.getInstance().getSession();Query query=session.createQuery(countHql);for (int i = 0; i < args.length; i++) {query.setParameter(i, args[i]);}int totalRecord=Integer.valueOf(query.uniqueResult()+"");query=session.createQuery(hql);for (int i = 0; i < args.length; i++) {query.setParameter(i, args[i]);}query.setFirstResult(pageSize*(currentPage-1));query.setMaxResults(pageSize);List<House> list=(List<House>)query.list();Page page=new Page();page.setCurrentPage(currentPage);page.setPageSize(pageSize);page.setTotalRecord(totalRecord);page.setList(list);return page;}
