Hibernate与Spring整合步骤:

第一步:加入Hibernate和Spring的相关jar包

第二步:创建application.xml文件,配置dataSource和session,

第三步：将sessionFactory对象注入到Dao实现类中，并操作数据库

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

	<bean id="userDao" class="com.hcj.dao.impl.UserDaoImpl">
		<!-- 将sessionFactory注入到Dao实现类中 -->
		<property name="sessionFactory" ref="sessionFactory"></property>
	</bean>
	<bean id="userServer" class="com.hcj.service.impl.UserServiceImpl">
		<!-- 动态添加userDao到UserServiceImpl对象中 -->
		<property name="userDao" ref="userDao"></property>
	</bean>

	<!-- 配置DataSource -->
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">
		<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
		<property name="url" value="jdbc:oracle:thin:@localhost:1521/orcl" />
		<property name="username" value="scott" />
		<property name="password" value="123456" />
	</bean>

	<!-- 配置sessionFactoty -->
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource" ref="dataSource" />
		<property name="mappingResources">
			<list>
				<value>User.hbm.xml
				</value>
			</list>
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="dialect">org.hibernate.dialect.Oracle9Dialect</prop>
				<prop key="show_sql">true</prop>
			</props>
		</property>
	</bean>
	

</beans>

UserServerImpl类

package com.hcj.service.impl;

import com.hcj.dao.UserDao;
import com.hcj.model.User;
import com.hcj.service.UserService;

public class UserServiceImpl implements UserService {
	private UserDao userDao; 
	
	public UserDao getUserDao() {
		return userDao;
	}

	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}

	@Override
	public void save(User user) {
		userDao.save(user);
	}
	
	public UserServiceImpl(){
		
	}
	
	public UserServiceImpl(UserDao userDao){
		this.userDao = userDao;
	}
	

}

package com.hcj.dao.impl;

import java.sql.Connection;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.Collection;
import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.Set;

import javax.sql.DataSource;

import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.classic.Session;

import com.hcj.dao.UserDao;
import com.hcj.model.User;

public class UserDaoImpl implements UserDao {
	private SessionFactory sessionFactory;
	
	
 	public SessionFactory getSessionFactory() {
		return sessionFactory;
	}


	public void setSessionFactory(SessionFactory sessionFactory) {
		this.sessionFactory = sessionFactory;
	}


	@Override
	public void save(User user){
		Session session = sessionFactory.openSession();
		Transaction tx = session.beginTransaction();
		try {
			session.save(user);
			tx.commit();
		} catch (Exception e) {
			if(tx != null){
				tx.rollback();
			}
		}finally{
			session.close();
		}
	}

}
