[coldspring-dev] init-method usage

[Jonathon Stierman]

Anyone have any examples of how this is used?  I’ve got a circular
dependency that I’d like to resolve by using this.  

I got a response from Peter Farrell, in a past thread:

>> <bean name="someService" id="dot.path.to.someService"
init-method="setup">
>> <property name="someOtherService"><ref bean="someOtherService"/></bean>
>> <property name="thatService"><ref bean=""thatService"/></bean>
>> </bean>
>>
>> Order of operations:
>> 1. Create someService
>> 2. Call init() with any constructor args (must resolve dependencies
first)
>> 3. Wiring in properties
>> 4. Call init-method (yes, it's a misleading name, but it follows the
Spring DTD here).  In my architecture, we 
>> call this the setup() method.

I figured ColdSpring would just run some magic on my properties and
automatically figure out that they should be set in the init-method rather
than in the init() constructor, but CS threw an error at me indicating it
was still looking for a generic set[myDependency]() method.  Here’s my
config.xml:

<!-- File loaded by ColdSpring to perform dependency injection -->
<beans>
        <bean id="Articles" class="Components.Articles" singleton="true">
                <constructor-arg
name="datasource"><value>${datasource}</value></constructor-arg>
        </bean>
        <bean id="Categories" class="Components.Categories" singleton="true"
init-method="setup">
                <constructor-arg
name="datasource"><value>${datasource}</value></constructor-arg>
                <property name="articleCFC"><ref bean="Articles"
/></property>
        </bean>
</beans>

And here’s my Categories.cfc:

<cfcomponent hint="Add/Edit/Delete Categories">
        <cfset Variables.datasource             = "" />
        <cfset Variables.articlesCFC    = "" />
        
        <cffunction name="init" access="public"
returntype="Components.Categories" hint="I initialize myself">
                <cfargument name="datasource"           type="string"
required="false" />
                
                <cfset Variables.datasource = arguments.datasource />
                
                <cfreturn this />
        </cffunction>
        
        <cffunction name="setup" access="public"
returntype="Components.Categories" hint="I post-initilize myself for
circular dependencies">
                <cfargument name="articlesCFC"
type="Components.Articles"      required="false" />
                
                <cfset Variables.articlesCFC = arguments.articlesCFC />
                
                <cfreturn this />
        </cffunction>
</cfcomponent>

What’s the syntax for making the init-method concept work?  I googled around
a bit, but kept getting matches regarding the regular init() constructor
rather than the init-method usage.
