根据属性分页查询

1.The Pager.java

package com.music.util.pager;

import java.util.ArrayList;
import java.util.List;

//分页  戚拂晓 2011.2.24
public class Pager {
	//页面大小

		this.lastPageNo = this.pageCount;
		if(this.lastPageNo==0){

	//输出每页显示记录数的数值列表

2.按属性分页查询

@SuppressWarnings("unchecked")
	public Pager pageLoad(final Integer pageNo, final Integer pageSize) {

		int rowCount = 0;
		Number number = (Number) this.hibernateTemplate.iterate("select count(*) from WebArticle").next();
		rowCount = number.intValue();
		System.out.println(pageNo);
		System.out.println(rowCount);
		List log =  getHibernateTemplate().executeFind(new HibernateCallback() {  
			public Object doInHibernate(Session session)  
			throws HibernateException, SQLException {
				int startIndex = pageSize * (pageNo-1);
				Query query = session.createQuery("from WebArticle order by updatetime desc");  
				query.setFirstResult(startIndex);  
				query.setMaxResults(pageSize);  
				List result = query.list();  
				return result;
			}

		});
		return new Pager(pageSize, pageNo, rowCount, log);
	}
