你是说向oracle数据库里增加一条记录吗？如果是这样的话，代码如下：另外发送到你的邮箱里：
IBaseDao;

package com.a*.;

import org.hibernate.Session;

public interface IBaseDao {
public Session getSession();
public void closeSession();
}

BaseDao:
package com.a*..impl;

import org.hibernate.HibernateException;
import org.hibernate.Session;

import com.a*..IBaseDao;

public class BaseDao implements IBaseDao {
private Session session = null;
public Session getSession(){
//Session session = null;
try {
session = HibernateUtil.getSessionFactory().openSession();
} catch (HibernateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
System.out.println("getSession()方法出错...");
}
return session;
}

public void closeSession(){
//Session session = getSession();
if(null != session){
session.close();
}
}
}

HibernateUtil:
package com.a*..impl;

import org.hibernate.HibernateException;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

public class HibernateUtil {
private static Configuration configuration;
private static SessionFactory sessionFactory;
static{
try {
configuration = new Configuration();
configuration.configure();
sessionFactory = configuration.buildSessionFactory();
} catch (HibernateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

public static Configuration getConfiguration(){
return configuration;
}

public static SessionFactory getSessionFactory(){
return sessionFactory;
}
}

ProctDaoImpl:
package com.a*..impl;

import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.Transaction;

import com.a*..IProctDao;
import com.a*.models.Proct;

public class ProctDaoImpl extends BaseDao implements IProctDao {

@Override
public boolean saveOrUpdate(Proct proct) {
// TODO Auto-generated method stub
boolean isSuccess = false;
Session session = null;
Transaction transaction = null;
try {
session = getSession();
transaction = session.beginTransaction();
transaction.begin();
session.saveOrUpdate(proct);
transaction.commit();
isSuccess = true;
} catch (HibernateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
transaction.rollback();
System.out.println("saveOrUpdate(Proct proct)方法出错了...");
}finally{
closeSession();
}
return isSuccess;
}
}
一个小例子追问请查分!
