一，1个接口：StatDAO.java
package com.statistic.DAO;
import java.util.List;
import org.hibernate.Session;
public interface StatDAO {
public void save(Object obj);
public void update(Object obj);
public void delete(Object obj);
public Object get(Class c, Long id);
public List findByPage(String hql, int pageSize, int pageNO);
public List findList(String hql);
public int getCount(String hql);
public void executeDel(String hql);
public Session getSess();
}
二，1个接口实现类：StatDAOImpl.java
继承HibernateDaoSupport
实现StatDAO.java
package com.statistic.DAO.impl;
import com.statistic.DAO.StatDAO;
import java.util.*;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import org.springframework.orm.hibernate3.HibernateCallback;
import org.hibernate.Session;
import org.hibernate.Query;
import java.sql.Statement;
import java.sql.SQLException;
public class StatDAOImpl extends HibernateDaoSupport implements StatDAO{
public StatDAOImpl() {
}
public void save(Object obj){
this.getHibernateTemplate().save(obj);
}
public void update(Object obj){
this.getHibernateTemplate().update(obj);
}
public void delete(Object obj){
this.getHibernateTemplate().delete(obj);
}
public Object get(Class c, Long id){
return this.getHibernateTemplate().get(c,id);
}
public List findByPage(String hql, int pageSize, int pageNO){
final String sql = hql;
final int firstRow = (pageNO - 1) * pageSize;
final int maxRow = pageSize;
List list = this.getHibernateTemplate().executeFind(new HibernateCallback() {
public Object doInHibernate(Session session) {
Query q = session.createQuery(sql);
q.setFirstResult(firstRow);
q.setMaxResults(maxRow);
return q.list();
}
}
);
return list;
}
public List findList(String hql){
return this.getHibernateTemplate().find(hql);
}
public int getCount(String hql){
int count = 0;
List list = this.getHibernateTemplate().find(hql);
if((list != null) && (list.size() != 0)) {
count = ((Long) list.get(0)).intValue();
}
return count;
}
/**
* 执行非查询的SQL语句，这里是删除
* @param hql String
*/
public void executeDel(String hql) {
final String sql = hql;
this.getHibernateTemplate().execute(new HibernateCallback() {
public Object doInHibernate(Session session) {
Statement stat =null;
try{
stat = session.connection().createStatement();
return new Integer(stat.executeUpdate(sql));
}catch(Exception e){
e.printStackTrace();
return null;
}finally{
try{
stat.close();
}catch(Exception e){
e.printStackTrace();
}
}
}
}
);
}
public Session getSess(){
return this.getHibernateTemplate().getSessionFactory().openSession();
}
}
三，商业逻辑
package com.statistic.business;
import com.statistic.DAO.StatDAO;
import java.util.List;
import java.util.ArrayList;
import com.statistic.bean.ItemDay;
import com.bean.Item;
public class ItemDayBO {
private StatDAO statDAO;
private com.business.ItemBO miscItemBO;
public void setMiscItemBO(com.business.ItemBO miscItemBO) {
this.miscItemBO = miscItemBO;
}
public void setStatDAO(StatDAO statDAO){
this.statDAO= statDAO;
}
public List getItemList(String type,String date1){
List list = new ArrayList();
String hql = "select * from ItemDay as i where i.typeid="+type+
" and i.downloadDate='"+date1+"'";
list = statDAO.findList(hql);
return list;
}
public List getTypeCount(String date1,String date2){
List list = new ArrayList();
String hql = "select i.typeid,sum(i.downloadTotal)";
return list;
}
public List[] getAvatatListBySubject(String date1,String str,String orderCol , String orderMode){
List[] list = new ArrayList[3];
String hql ="from ItemDay i "+
" where i.typeid=1 and ("+str+
") and i.downloadDate='"+date1+"' "+
" order by "+orderCol +" "+orderMode;
List tempList = statDAO.findList(hql);
list[0]=new ArrayList();
list[1]=new ArrayList();
list[2]=new ArrayList();
for(int i =0;i<tempList.size();i++){
ItemDay itemDay = (ItemDay)tempList.get(i);
Item item = avatarItemBO.get(itemDay.getProductid());
if(item!=null){
itemDay.setName(item.getName());
if(itemDay.getSex()==1){
list[0].add(itemDay);
}else if(itemDay.getSex()==2){
list[1].add(itemDay);
}else{
list[2].add(itemDay);
}
}
}
return list;
}
public List getMiscListBySubject(String date1,String str,String orderCol , String orderMode){
List list = new ArrayList();
String hql = "from ItemDay i where i.downloadDate='"+date1+"' and i.code like '"+str+ "' order by "+orderCol +" "+orderMode;
list = statDAO.findList(hql);
for(int i =0;i<list.size();i++){
((ItemDay)list.get(i)).setName((miscItemBO.get(((ItemDay)list.get(i)).getProductid()).getName()));
}
return list;
}
public String[] getTotalCount(String date1,String type){
String[] counts = new String[2];
String hql = "select sum(i.downloadTotal),sum(i.clickTotal) from ItemDay i "+
"where i.downloadDate='"+date1+"' and i.code like '"+type+"'";
List list = statDAO.findList(hql);
Object[] objs = (Object[])list.get(0);
counts[0] = objs[0]+"";
counts[1] = objs[1]+"";
return counts;
}
}
