前段时间对Spring的事务配置做了比较深入的研究，在此之间对Spring的事务配置虽说也配置过，但是一直没有一个清楚的认识。通过这次的学习发觉Spring的事务配置只要把思路理清，还是比较好掌握的。

    总结如下：

    Spring配置文件中关于事务配置总是由三个组成部分，分别是DataSource、TransactionManager和代理机制这三部分，无论哪种配置方式，一般变化的只是代理机制这部分。

   DataSource、TransactionManager这两部分只是会根据数据访问方式有所变化，比如使用Hibernate进行数据访问时，DataSource实际为SessionFactory，TransactionManager的实现为HibernateTransactionManager。

    具体如下图：

    根据代理机制的不同，总结了五种Spring事务的配置方式，配置文件如下：

    第一种方式：每个Bean都有一个代理

<?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:context="http://www.springframework.org/schema/context"
 xmlns:aop="http://www.springframework.org/schema/aop"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
 http://www.springframework.org/schema/context
 http://www.springframework.org/schema/context/spring-context-2.5.xsd
 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd"> 

 <bean id="sessionFactory" 
 class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
 <property name="configLocation" value="classpath:hibernate.cfg.xml" /> 
 <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" /> 
 </bean> 

 <!-- 定义事务管理器（声明式的事务） --> 
 <bean id="transactionManager"
 class="org.springframework.orm.hibernate3.HibernateTransactionManager">
 <property name="sessionFactory" ref="sessionFactory" /> 
 </bean> 
 
 <!-- 配置DAO --> 
 <bean id="userDaoTarget" class="com.bluesky.spring.dao.UserDaoImpl">
 <property name="sessionFactory" ref="sessionFactory" /> 
 </bean> 
 
 <bean id="userDao" 
 class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"> 
 <!-- 配置事务管理器 --> 
 <property name="transactionManager" ref="transactionManager" /> 
 <property name="target" ref="userDaoTarget" /> 
 <property name="proxyInterfaces" value="com.bluesky.spring.dao.GeneratorDao" /> 
 <!-- 配置事务属性 --> 
 <property name="transactionAttributes"> 
 <props> 
 <prop key="*"> PROPAGATION_REQUIRED </prop> 
 </props> 
 </property> 
 </bean> 
 </beans>

    第二种方式：所有Bean共享一个代理基类

<?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:context="http://www.springframework.org/schema/context"
 xmlns:aop="http://www.springframework.org/schema/aop"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
 http://www.springframework.org/schema/context
 http://www.springframework.org/schema/context/spring-context-2.5.xsd
 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd"> 

 <bean id="sessionFactory" 
 class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
 <property name="configLocation" value="classpath:hibernate.cfg.xml" /> 
 <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" /> 
 </bean> 

 <!-- 定义事务管理器（声明式的事务） --> 
 <bean id="transactionManager"
 class="org.springframework.orm.hibernate3.HibernateTransactionManager">
 <property name="sessionFactory" ref="sessionFactory" /> 
 </bean> 
 
 <bean id="transactionBase" 
 class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean" 
 lazy-init="true" abstract="true"> 
 <!-- 配置事务管理器 --> 
 <property name="transactionManager" ref="transactionManager" /> 
 <!-- 配置事务属性 --> 
 <property name="transactionAttributes"> 
 <props> 
 <prop key="*">PROPAGATION_REQUIRED </prop> 
 </props> 
 </property> 
 </bean> 
 
 <!-- 配置DAO --> 
 <bean id="userDaoTarget" class="com.bluesky.spring.dao.UserDaoImpl">
 <property name="sessionFactory" ref="sessionFactory" /> 
 </bean> 
 
 <bean id="userDao" parent="transactionBase"> 
 <property name="target" ref="userDaoTarget" /> 
 </bean> 
 </beans>

第三种方式：使用拦截器

<?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:context="http://www.springframework.org/schema/context"
 xmlns:aop="http://www.springframework.org/schema/aop"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
 http://www.springframework.org/schema/context
 http://www.springframework.org/schema/context/spring-context-2.5.xsd
 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd"> 

 <bean id="sessionFactory" 
 class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
 <property name="configLocation" value="classpath:hibernate.cfg.xml" /> 
 <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" /> 
 </bean> 

 <!-- 定义事务管理器（声明式的事务） --> 
 <bean id="transactionManager"
 class="org.springframework.orm.hibernate3.HibernateTransactionManager">
 <property name="sessionFactory" ref="sessionFactory" /> 
 </bean> 
 
 <bean id="transactionInterceptor" 
 class="org.springframework.transaction.interceptor.TransactionInterceptor"> 
 <property name="transactionManager" ref="transactionManager" /> 
 <!-- 配置事务属性 --> 
 <property name="transactionAttributes"> 
 <props> 
 <prop key="*">PROPAGATION_REQUIRED </prop> 
 </props> 
 </property> 
 </bean> 
 
 <bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"> 
 <property name="beanNames"> 
 <list> 
 <value> *Dao </value> 
 </list> 
 </property> 
 <property name="interceptorNames"> 
 <list> 
 <value> transactionInterceptor </value> 
 </list> 
 </property> 
 </bean> 
 
 <!-- 配置DAO --> 
 <bean id="userDao" class="com.bluesky.spring.dao.UserDaoImpl">
 <property name="sessionFactory" ref="sessionFactory" /> 
 </bean> 
 </beans>

第四种方式：使用tx标签配置的拦截器

<?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:context="http://www.springframework.org/schema/context"
 xmlns:aop="http://www.springframework.org/schema/aop"
 xmlns:tx="http://www.springframework.org/schema/tx"
 xsi:schemaLocation="http://www.springframework.org/schema/beans
 http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
 http://www.springframework.org/schema/context
 http://www.springframework.org/schema/context/spring-context-2.5.xsd
 http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
 http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd"> 

 <context:annotation-config /> 
 <context:component-scan base-package="com.bluesky" /> 

 <bean id="sessionFactory" 
 class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> 
 <property name="configLocation" value="classpath:hibernate.cfg.xml" /> 
 <property name="configurationClass" value="org.hibernate.cfg.AnnotationConfiguration" /> 
 </bean> 

 <!-- 定义事务管理器（声明式的事务） --> 
 <bean id="transactionManager"
 class="org.springframework.orm.hibernate3.HibernateTransactionManager">
 <property name="sessionFactory" ref="sessionFactory" /> 
 </bean> 

 <tx:advice id="txAdvice" transaction-manager="transactionManager">
 <tx:attributes> 
 <tx:method name="*" propagation="REQUIRED" /> 
 </tx:attributes> 
 </tx:advice> 
 
 <aop:config> 
 <aop:pointcut id="interceptorPointCuts"
 expression="execution(*com.bluesky.spring.dao.*.*(..))" /> 
 <aop:advisor advice-ref="txAdvice"
 pointcut-ref="interceptorPointCuts" /> 
 </aop:config> 
 </beans>
