1. Spring 整合 Hibernate 整合什么 ?  
1). 有 IOC 容器来管理 Hibernate 的 SessionFactory

2). 让 Hibernate 使用上 Spring 的声明式事务

2. 整合步骤:  
1). 加入 hibernate  
①. jar 包  
②. 添加 hibernate 的配置文件: hibernate.cfg.xml  
③. 编写了持久化类对应的 .hbm.xml 文件。   
  
  
2). 加入 Spring  
①. jar 包  
②. 加入 Spring 的配置文件  
  
  
3). 整合.

3. 编写代码

其中最重要的就是配置文件的位置。

spring配置文件

    	</bean>
    	
    	
    	<bean id="sessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

    	</bean>
    
    	
    	
    	<bean id="transactionManager" class="org.springframework.orm.hibernate4.HibernateTransactionManager">

    		</tx:attributes>
    	</tx:advice>
    
    	
    	<aop:config>

    			id="txPointcut"/>
    		<aop:advisor advice-ref="txAdvice" pointcut-ref="txPointcut"/>
    	</aop:config>
    
    </beans>

hibernate配置文件

<?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE hibernate-configuration PUBLIC
    		"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
    		"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
    <hibernate-configuration>
        <session-factory>
        
        	
        	
        	
        	
        	<property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
    
    		<property name="hibernate.show_sql">true</property>
    		<property name="hibernate.format_sql">true</property>
    		
    		<property name="hibernate.hbm2ddl.auto">update</property>
    		
    		
    		    	
        </session-factory>
    </hibernate-configuration>

最后还设计到每一个类的-hbm.xml配置文件就行了
