TransactionAttributeSource,TransactionAttribute

[/b][b]每一个方法执行都会应用事务，它回传的transactionAttribute实例的默认传播行为是PROPAGATION_REQUIRED,隔离层级为ISOLATION_REFAULE

<bean id="informationDAOProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
  		  <property name="proxyInterfaces">
		  	<list>
		  		<value>
		  			com.gsvince.hibernate.Idao.IInformationDAO
		  		</value>
		  	</list>
		  </property>
		  <property name="transactionManager">
		   <ref bean="transactionManager" />
		  </property>
		  <property name="target">
		   <ref local="informationDAO" />
		  </property>
		  <property name="transactionAttributeSource">
		   <ref bean="transactionAttributeSource"/>
		  </property>
	</bean>
	
	<bean id="transactionAttributeSource" class="org.springframework.transaction.interceptor.MatchAlwaysTransactionAttributeSource">
	</bean>

也可以使用org.springframework.transaction.interceptor.DefaultTransactionAttribute，并设置自己的事务策略，之后设置给transactionAttributeSource，例如:

<bean id="myTransactionAttribute" class="org.springframework.transaction.interceptor.DefaultTransactionAttribute">
		<property name="propagationBehaviorName" 
				value="PROPAGATION_REQUIRES_NEW"/>
		<property name="isolationLevelName" 
				value="ISOLATION_REPEATABLE_READ"/>
	</bean>
	
	<bean id="transactionAttributeSource" class="org.springframework.transaction.interceptor.MatchAlwaysTransactionAttributeSource">
		<property name="transactionAttribute" 
				ref="myTransactionAttribute"/>
	</bean>

	<bean id="informationDAOProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
  		  <property name="proxyInterfaces">
		  	<list>
		  		<value>
		  			com.gsvince.hibernate.Idao.IInformationDAO
		  		</value>
		  	</list>
		  </property>
		  <property name="transactionManager">
		   <ref bean="transactionManager" />
		  </property>
		  <property name="target">
		   <ref local="informationDAO" />
		  </property>
		  <property name="transactionAttributeSource"
		   		ref="transactionAttributeSource"/>
	</bean>

也可以使用org.springframework.transaction.interceptor.NameMatchTransactionAttributeSource来指定某些方法要应用事务，以及要应用的事务策略，例如：

<bean id="transactionAttributeSource" class="org.springframework.transaction.interceptor.NameMatchTransactionAttributeSource">
		<property name="properties">
			<props>
				<prop key="edit*">PROPAGATION_REQUIRED</prop>
			    <prop key="insert*">PROPAGATION_REQUIRED</prop>
			    <prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
			    <prop key="delete*">PROPAGATION_REQUIRED</prop>
			</props>
		</property>
	</bean>
	
	<bean id="informationDAOProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
  		  <property name="proxyInterfaces">
		  	<list>
		  		<value>
		  			com.gsvince.hibernate.Idao.IInformationDAO
		  		</value>
		  	</list>
		  </property>
		  <property name="transactionManager">
		   <ref bean="transactionManager" />
		  </property>
		  <property name="target">
		   <ref local="informationDAO" />
		  </property>
		  <property name="transactionAttributeSource"
		   		ref="transactionAttributeSource"/>
	</bean>	

在NameMatchTransactionAttributeSource的"properties"属性上，可以指定方法名称与事务策略，方法名称的指定可以指定全名，也可以使用Wildcard来指定，例如上面的指定中，只要方法名以insert开头的都会应用相对应的事务策略。
