　　以前项目中经常用spring 事务处理还没有亲自配置过惭愧现在马上上路．

　　首先在spring容器中配置transactionManager 这个有好多实现这里以HibernateTransactionManager为例

　　 <bean id= transactionManager class= springframework orm hibernate HibernateTransactionManager > <property name= sessionFactory > <ref local= sessionFactory /> </property> </bean> 然后再定义一个事务模板 <bean id= txProxyTemplate abstract= true class= springframework transaction interceptor TransactionProxyFactoryBean > <property name= transactionManager > <ref bean= transactionManager /> </property> <property name= transactionAttributes > <props> <prop key= save* >PROPAGATION_REQUIRED Exception</prop> <prop key= remove* >PROPAGATION_REQUIRED Exception</prop> <prop key= update* >PROPAGATION_REQUIRED Exception</prop> <prop key= incress* >PROPAGATION_REQUIRED Exception</prop> <prop key= * >PROPAGATION_REQUIRED</prop> </props> </property> </bean> 这个模板怎样应用到业务方法上呢？请看下面的配置 <! <bean id= userService class= sclsch service impl UserServiceImpl > <property name= userDao > <ref bean= BmUserDAO /> </property> </bean> > <! 为userService配置事务 > <bean id= userService parent= txProxyTemplate > <property name= target > <bean class= sclsch service impl UserServiceImpl > <property name= userDao > <ref bean= BmUserDAO /> </property> </bean> </property> </bean>
