RE: [Springframework-developer] commons attributes questions

[Cameron B. <ca...@da...>]

Yeah, I am using commons attributes for transaction declaration.

We have a system where we use a method name match transaction attribute
source as the fallback, and allow declarations on at the method level to
override these defaults, since most of the time the defaults work perfectly,
and these defaults are defined per application anyway.


Something like this in applicationContext.xml

<bean id="commonsAttributes"
class="org.springframework.metadata.commons.CommonsAttributes"/>

<!-- transaction attribute source to provide a method name based map -->
<bean id="attributesMatchMethodNamePattern"
class="org.springframework.transaction.interceptor.NameMatchTransactionAttri
buteSource">
	<property name="properties">
		<props>
			<!-- read only methods -->
			<prop
key="list*">PROPAGATION_REQUIRED,readOnly</prop>
			<prop
key="find*">PROPAGATION_REQUIRED,readOnly</prop>
			<prop
key="get*">PROPAGATION_REQUIRED,readOnly</prop>
			<prop
key="load*">PROPAGATION_REQUIRED,readOnly</prop>
			<!-- the default is transactional (least specific,
match everything) -->
			<prop key="*">PROPAGATION_REQUIRED</prop>
		</props>
	</property>
</bean>

<bean id="attributesAttributeSource"
class="org.springframework.transaction.interceptor.AttributesTransactionAttr
ibuteSource">
	<constructor-arg><ref bean="commonsAttributes"/></constructor-arg>
</bean>


<bean id="multiAttributeSource"
class="transaction.interceptor.ListTransactionAttributeSource">
	<property name="attributeSources">
		<list>
			<ref bean="attributesAttributeSource"/>
			<ref bean="attributesMatchMethodNamePattern"/>
		</list>
	</property>
</bean>
