Here's a concrete example. In a Manager CFC I have
<cffunction name="getAll" output="false">
<cfargument name="username" required="true">
<cfset var ret=structNew()>
<cfset
ret.data=variables.reactor.createGateway("plans").getByFields(creatorName=arguments.username,sortByFieldList="name")>
<cfset ret.result=true>
<cfreturn ret />
</cffunction>
<cffunction name="get" output="false">
<cfargument name="username" required="true">
<cfargument name="id" required="true" type="numeric">
<cfset var ret=structNew()>
<cfset
ret.data=variables.reactor.createRecord("plans").load(creatorName=arguments.username,id=arguments.id)>
<cfset ret.result=true>
<cfreturn ret />
</cffunction>
this CFC is exposed through ColdSpring's RemoteProxyBean, and the methods will
of course return a Record and a Query respectively in result.DATA, but we'd
rather it returned either a TO or an array of TO.
So we just configure some BeforeAdvice for the RemoteProxyBean
(via 'flashUtilityService'):
<bean id="reactorUtilityServicePlans"
class="com.halliwells.CFCs.aop.ReactorUtilityService">
<property name="queryObject">
<value>com.halliwells.CFCs.t3ster.data.To.planTo</value>
</property>
<property name="reactor">
<ref bean="reactor"/>
</property>
</bean>
<bean id="remotePlanService"
class="coldspring.aop.framework.RemoteFactoryBean">
<property name="target">
<ref bean="planManager" />
</property>
<property name="serviceName">
<value>RemotePlanService</value>
</property>
<property name="relativePath">
<value>/com/halliwells/CFCs/t3ster/service/</value>
</property>
<property name="beanFactoryName">
<value>beanFactory</value>
</property>
<property name="flashUtilityService">
<ref bean="reactorUtilityServicePlan" />
</property>
</bean>
The Advice itself is fairly easy, but I've got to see about getting it
released from work, or redo it as a clean-room implementation at home, or
something.
