上午没事抽空做了一个datagrid的入门例子，是结合struts2做的，刚下班了，也闲着没事，就datagrid的再做进一步的开发；进行分页 操作 另外本人有一个习惯，拒绝转载或者抄袭他人的东西.此外，事例源码尽量完整，哪怕最简单的代码也要写的清楚 . 

 先看效果：

DAO数据库访问层
接口EasyDao：
package org.easyui.dao;
import java.util.List;
import org.easyui.model.Student;
public interface EasyDao {
  public List<Student> getStudent(int page,int rows);
  public int getTotalPages(int rows);
 }接口实现类EasyDaoImpl：
package org.easyui.dao;
import java.util.List;
import org.easyui.model.Student;
 import org.easyui.util.UtilHibernate;
 import org.hibernate.HibernateException;
 import org.hibernate.Session;public class EasyDaoImpl implements EasyDao {
 @SuppressWarnings("unchecked")
  public List<Student> getStudent(int page, int rows) {
   List<Student> list = null;
   Session session = UtilHibernate.getSession();
   try {
    session.beginTransaction();
    String sql = "from Student";
    list = session.createQuery(sql)
         .setFirstResult((page-1)*rows)
         .setMaxResults(rows)
         .list();
    session.getTransaction().commit();
   } catch (HibernateException e) {
    session.getTransaction().rollback();
    e.printStackTrace();
   }finally{
    UtilHibernate.closeSession(session);
   }
   
   return list;
  } public int getTotalPages() {
   Session session = UtilHibernate.getSession();
   int total = 0;
   try {
    session.beginTransaction();
    String sql = "select count(*) from Student";
    int count = (Integer)session.createQuery(sql).uniqueResult();
    total =count;
    session.getTransaction().commit();
   } catch (HibernateException e) {
    session.getTransaction().rollback();
    e.printStackTrace();
   }finally{
    UtilHibernate.closeSession(session);
   }
   return total;
  }}
