spring事务配置

1、一个dao一个事务管理

<bean id="userDao" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
		<property name="transactionManager" ref="transactioinManager"/>
		<property name="target" ref="userDaoTarget"/>
		<property name="proxyInterfaces" value="login.dao.UserDAO"/>
		<property name="transactionAttributes">
			<props>
				<prop key="*">PROPAGETION_PRQUIRED</prop>
			</props>
		</property>			
	</bean>

 2、多个类共用一个事务管理

<bean id="transactionBase" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
		<property name="transactionManager" ref="transactioinManager"/>
		<property name="transactionAttributes">
			<props>
				<prop key="*">PROPAGETION_PRQUIRED</prop>
			</props>
		</property>			
	</bean>
	<bean id="userDao" parent="transactionBase">
		<property name="target" ref="userDaoTarget"></property>
	</bean>

 3、用拦截器拦截事务

<!-- 定义一个事务拦截器 -->
	<bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
		<property name="transactionManager" ref="transactioinManager"/>
		<property name="transactionAttributes">
			<props>
				<prop key="*">PROPAGETION_PRQUIRED</prop>
			</props>
		</property>			
	</bean>
	<!-- 使用自动代理 -->
	<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>
	<bean id="userDao" class="login.dao.UserDAO">
		<property name="sessionFactory">
			<ref bean="sessionFactory" />
		</property>
	</bean>

 4、使用tx标签来定义一个事务拦截器

<tx:advice id="txAdvice" transaction-manager="transactionManager">
		<tx:attributes>
			<tx:method name="*" propagation="REQUIRED"/>
		</tx:attributes>
	</tx:advice>
	<aop:config>
		<aop:pointcut expression="execution(* login.dao.*.*(..))" id="interceptionPointCut"/>
		<aop:advisor advice-ref="txAdvice" pointcut-ref="interceptionPointCut"/>
	</aop:config>
	<bean id="userDao" class="login.dao.UserDAO">
		<property name="sessionFactory">
			<ref bean="sessionFactory" />
		</property>
	</bean>

 5、全部用注解
