struts2.1.8.1+hibernate3.5.6Final的分页
1、CompanyDaoImpl.java
package com.xun.dao;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import com.xun.model.Company;
import com.xun.util.HibernateUtil;
public class CompanyDaoImpl {
public int count() {
int intRowCount = 0;//总行数
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
intRowCount = ((Number)(session.createQuery("select count(*) from Company")).uniqueResult()).intValue();
session.getTransaction().commit();
return intRowCount;
}
@SuppressWarnings("unchecked")
public List<Company> queryByPage(int i, int pageSize) {
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
Query q = session.createQuery("from Company as c ");
q.setFirstResult(i);
q.setMaxResults(pageSize);
List<Company> companies = (List<Company>)q.list();
session.getTransaction().commit();
return companies;
}
}
2、CompanyAction.java
package com.xun.action;

private Integer id;
private Company company;
private CompanyService companyService = new CompanyService();

private int k;//储存最大页面数
private int pageNow=1; //页码数,初始为1
private int pageSize = 8 ; //页面行数

}

pageNow = intPageCount;
i = (pageNow -1)*pageSize;
CompanyDaoImpl nlist = new CompanyDaoImpl();

}
public int getPageNow() {
return pageNow;
}
public void setPageNow(int pageNow) {

}
public int getPageSize() {

}
public void setPageSize(int pageSize) {

}
public int getIntRowCount() {
