[Springframework-developer] MethodPointcut support in TransactionProxyFactoryBean

[Kopylenko, D. <dko...@ac...>]

Hi everybody, 
TransactionProxyFactoryBean now supports MethodPointcut property, so now
it's possible to cause a conditional invokation of TransactionInterceptor
based on method name and attributes. The default is AlwaysInvoked method
pointcut. It could be set like this:
<bean id="myBusinessRegexpPointcut" 
	class="org.springframework.aop.framework.RegexpMethodPointcut"> 
	<property name="pattern"><value>*myBusiness*</value></property> 
</bean> 
<bean id="myBusinessService" 
	
class="org.springframework.transaction.interceptor.TransactionProxyFactoryBe
an"> 
	<property name="transactionManager"><ref
bean="myTransactionManager"/></property> 
	<property name="target"><ref
bean="myBusinessServiceTarget"/></property> 
	<property name="methodPointcut"><ref
bean="myBusinessRegexpPointcut"/></property> 
	<property name="proxyInterfacesOnly"><value>true</value></property> 
	<property name="transactionAttributes"> 
		<props> 
			<prop key="myBusiness*">PROPAGATION_REQUIRED</prop> 
			<prop
key="myBusinessMethod">PROPAGATION_MANDATORY</prop> 
		</props> 
	</property> 
</bean> 
So suppose in your Business Object not all the methods are "transactional",
so you could define a pointcut just for those tx methods and when a non-tx
method is invoked on the Proxy, the Tx interceptor does not get invoked
alltogether, passing the invokation right to the target object.
