SSH分頁-2

Entity（pojo、model）實體類

public class Fenye {
	//總頁數
	private int total;
	//當前頁數
	private List pagelist;
	
	public List getPagelist() {
		return pagelist;
	}
	public void setPagelist(List pagelist) {
		this.pagelist = pagelist;
	}
	public int getTotal() {
		return total;
	}
	public void setTotal(int total) {
		this.total = total;
	}
}

DAO層：

public interface PageDao {
/*	
 * offset  從第幾條記錄開始查詢
   pagesize  每頁顯示多少條記錄
	 */
	public Fenye allpage(int offset,int pagesize);
}

DAOIMPL層：

public class PageDaoImpl extends HibernateDaoSupport implements PageDao {

	public Fenye allpage(int offset, int pagesize) {
	//  得到總記錄數
		  String queryCountHql="select count(*) from PersonInfo";
		  Query query = getSession().createQuery(queryCountHql);
		  int total = ((Long)query.uniqueResult()).intValue();
		  List datas = getSession().createQuery("from PersonInfo").setFirstResult
		(offset).setMaxResults(pagesize).list();
		  Fenye pageModel=new Fenye();
		  pageModel.setTotal(total);
		  pageModel.setPagelist(datas);;
		  return pageModel;
	}

}

Service層：

public interface PageService {
	public Fenye allpages(int offset11,int pagesize11);
}

ServiceImpl層：

public class PageServiceImpl implements PageService {
	@Resource
	private PageDao pageDao;

	public Fenye allpages(int offset, int pagesize) {
		// TODO Auto-generated method stub
		return pageDao.allpage(offset, pagesize);
	}
	

}

Action層：

public class PageAction extends ActionSupport {
	@Resource
	private PageService pageService;
	public String  getpage(){
		 int pagesize=3;
		  int offset=0;
		  HttpServletRequest request = ServletActionContext.getRequest(); 
		//  HttpServletResponse response = ServletActionContext.getResponse();
		  if(request.getParameter("pager.offset")!=null)
		   offset=Integer.parseInt(request.getParameter("pager.offset"));
		  Fenye pm = this.pageService.allpages(offset, pagesize);
//		  Fenye pm=this.getPersonService().queryAllPerson(offset, pagesize);
		  request.setAttribute("pm", pm);
		  return "pagertaglib";
		
	}
}
