Spring事务配置的五种方式 以下文字资料是由(全榜网网www.cha138.com)小编为大家搜集整理后发布的内容，让我们赶快一起来看一下吧！

　　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= encoding= UTF ?><beans xmlns= xmlns:xsi= instance xmlns:context= xmlns:aop= xsi:schemaLocation= beans xsd context xsd aop xsd > <bean id= sessionFactory class= springframework orm hibernate LocalSessionFactoryBean > <property name= configLocation value= classpath:hibernate cfg xml /> <property name= configurationClass value= hibernate cfg AnnotationConfiguration /> </bean> <! 定义事务管理器（声明式的事务） > <bean id= transactionManager class= springframework orm hibernate HibernateTransactionManager > <property name= sessionFactory ref= sessionFactory /> </bean> <! 配置DAO > <bean id= userDaoTarget class= bluesky spring dao UserDaoImpl > <property name= sessionFactory ref= sessionFactory /> </bean> <bean id= userDao class= 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= 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= encoding= UTF ?><beans xmlns= xmlns:xsi= instance xmlns:context= xmlns:aop= xsi:schemaLocation= beans xsd context xsd aop xsd > <bean id= sessionFactory class= springframework orm hibernate LocalSessionFactoryBean > <property name= configLocation value= classpath:hibernate cfg xml /> <property name= configurationClass value= hibernate cfg AnnotationConfiguration /> </bean> <! 定义事务管理器（声明式的事务） > <bean id= transactionManager class= springframework orm hibernate HibernateTransactionManager > <property name= sessionFactory ref= sessionFactory /> </bean> <bean id= transactionBase class= 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= 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= encoding= UTF ?><beans xmlns= xmlns:xsi= instance xmlns:context= xmlns:aop= xsi:schemaLocation= beans xsd context xsd aop xsd > <bean id= sessionFactory class= springframework orm hibernate LocalSessionFactoryBean > <property name= configLocation value= classpath:hibernate cfg xml /> <property name= configurationClass value= hibernate cfg AnnotationConfiguration /> </bean> <! 定义事务管理器（声明式的事务） > <bean id= transactionManager class= springframework orm hibernate HibernateTransactionManager > <property name= sessionFactory ref= sessionFactory /> </bean> <bean id= transactionInterceptor class= 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= 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= 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= encoding= UTF ?><beans xmlns= xmlns:xsi= instance xmlns:context= xmlns:aop= xmlns:tx= xsi:schemaLocation= beans xsd context xsd aop xsd tx xsd > <context:annotation config /> <context:ponent scan base package= bluesky /> <bean id= sessionFactory class= springframework orm hibernate LocalSessionFactoryBean > <property name= configLocation value= classpath:hibernate cfg xml /> <property name= configurationClass value= hibernate cfg AnnotationConfiguration /> </bean> <! 定义事务管理器（声明式的事务） > <bean id= transactionManager class= springframework orm hibernate 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(* bluesky spring dao * *( )) /> <aop:advisor advice ref= txAdvice pointcut ref= interceptorPointCuts /> </aop:config> </beans>

　　第五种方式全注解

<?xml version= encoding= UTF ?><beans xmlns= xmlns:xsi= instance xmlns:context= xmlns:aop= xmlns:tx= xsi:schemaLocation= beans xsd context xsd aop xsd tx xsd > <context:annotation config /> <context:ponent scan base package= bluesky /> <tx:annotation driven transaction manager= transactionManager /> <bean id= sessionFactory class= springframework orm hibernate LocalSessionFactoryBean > <property name= configLocation value= classpath:hibernate cfg xml /> <property name= configurationClass value= hibernate cfg AnnotationConfiguration /> </bean> <! 定义事务管理器（声明式的事务） > <bean id= transactionManager class= springframework orm hibernate HibernateTransactionManager > <property name= sessionFactory ref= sessionFactory /> </bean> </beans> package bluesky spring dao;import java util List;import hibernate SessionFactory;import springframework beans factory annotation Autowired;import springframework orm hibernate support HibernateDaoSupport;import springframework stereotype Component;import bluesky spring domain User;@Transactional@Component( userDao )public class UserDaoImpl extends HibernateDaoSupport implements UserDao public List<User> listUsers() return this getSession() createQuery( from User ) list(); cha138/Article/program/Java/ky/201311/28887
