Spring事务配置(收集)

Spring事务配置的五种方式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?xmlversion=1.0encoding=UTF-8?beansxmlns=:xsi=:context=:aop=:schemaLocation=://://://://://=sessionFactoryclass=org.springframework.orm.hibernate3.LocalSessionFactoryBeanpropertyname=configLocationvalue=classpath:hibernate.cfg.xml/propertyname=configurationClassvalue=org.hibernate.cfg.AnnotationConfiguration//bean!--定义事务管理器（声明式的事务）--beanid=transactionManagerclass=org.springframework.orm.hibernate3.HibernateTransactionManagerpropertyname=sessionFactoryref=sessionFactory//bean!--配置DAO--beanid=userDaoTargetclass=com.bluesky.spring.dao.UserDaoImplpropertyname=sessionFactoryref=sessionFactory//beanbeanid=userDaoclass=org.springframework.transaction.interceptor.TransactionProxyFactoryBean!--配置事务管理器--propertyname=transactionManagerref=transactionManager/propertyname=targetref=userDaoTarget/propertyname=proxyInterfacesvalue=com.bluesky.spring.dao.GeneratorDao/!--配置事务属性--propertyname=transactionAttributespropspropkey=*PROPAGATION_REQUIRED/prop/props/property/bean/beans第二种方式：所有Bean共享一个代理基类?xmlversion=1.0encoding=UTF-8?beansxmlns=:xsi=:context=:aop=:schemaLocation=://://://://://=sessionFactoryclass=org.springframework.orm.hibernate3.LocalSessionFactoryBeanpropertyname=configLocationvalue=classpath:hibernate.cfg.xml/propertyname=configurationClassvalue=org.hibernate.cfg.AnnotationConfiguration//bean!--定义事务管理器（声明式的事务）--beanid=transactionManagerclass=org.springframework.orm.hibernate3.HibernateTransactionManagerpropertyname=sessionFactoryref=sessionFactory//beanbeanid=transactionBaseclass=org.springframework.transaction.interceptor.TransactionProxyFactoryBeanlazy-init=trueabstract=true!--配置事务管理器--propertyname=transactionManagerref=transactionManager/!--配置事务属性--propertyname=transactionAttributespropspropkey=*PROPAGATION_REQUIRED/prop/props/property/bean!--配置DAO--beanid=userDaoTargetclass=com.bluesky.spring.dao.UserDaoImplpropertyname=sessionFactoryref=sessionFactory//beanbeanid=userDaoparent=transactionBasepropertyname=targetref=userDaoTarget//bean/beans第三种方式：使用拦截器?xmlversion=1.0encoding=UTF-8?beansxmlns=:xsi=:context=:aop=:schemaLocation=://://://://://=sessionFactoryclass=org.springframework.orm.hibernate3.LocalSessionFactoryBeanpropertyname=configLocationvalue=classpath:hibernate.cfg.xml/propertyname=configurationClassvalue=org.hibernate.cfg.AnnotationConfiguration//bean!--定义事务管理器（声明式的事务）--beanid=transactionManagerclass=org.springframework.orm.hibernate3.HibernateTransactionManagerpropertyname=sessionFactoryref=sessionFactory//beanbeanid=transactionInterceptorclass=org.springframework.transaction.interceptor.TransactionInterceptorpropertyname=transactionManagerref=transactionManager/!--配置事务属性--propertyname=transactionAttributespropspropkey=*PROPAGATION_REQUIRED/prop/props/property/beanbeanclass=org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreatorpropertyname=beanNameslistvalue*Dao/value/list/propertypropertyname=interceptorNameslistvaluetransactionInterceptor/value/list/property/bean!--配置DAO--beanid=userDaoclass=com.bluesky.spring.dao.UserD
