Hibernate分页的两种实现方法
本文实例讲述了Hibernate分页的两种实现方法。分享给大家供大家参考,具体如下:
1. criteria分页
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; }
2. hql分页
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; }
希望本文所述对大家基于Hibernate框架的Java程序设计有所帮助。
