I am trying to get my head around ColdBox and ColdSpring (manly ColdSpring) so
please be kind and any example code with comments would be much appreciate.
My question
I have a CFC called model/common.cfc
This CFC contains all my SQL code that interacts with the database. However in
common.cfc I currently use the following code inside common.cfc on init() to
get my DNS details...
<!-------- CONSTRUCTOR -------->
<cfproperty name="dsn" type="coldbox:datasource:DBDetails"
scope="instance"><!---inject datasource--->
<cfscript>
instance = structnew();
</cfscript>
<cffunction name="init" access="public" returntype="any" output="false">
<cfargument name="dsn" type="any" _wireme="coldbox:datasource:DBDetails" />
<cfreturn this>
</cffunction>
I can then call it anywhere inside common like so #instance.dsn.getName()#
Now this works fine, but wanting to expand my knowledge I have decided to
introduced ColdSpring (no experience of it before) I understand why I would use
an IOC so I wanted to start simple.
I want to replace the above code and inject the DNS details into common.cfc and
use âoneâ bean for all.
I have followed the documentation on CB but am struggling mainly because of my
understanding I think. Here is what I have so far....
I created my coldspring.xml (below) what I think it should do is inject DNS
into UserService.cfc this cfc is then called by common (userGateway). then in
my handler i can just called the one bean, right...
coldspring.xml...
<beans>
<bean id="coldboxFactory" class="coldbox.system.extras.ColdboxFactory"
/>
<bean id="ConfigBean" factory-bean="ColdboxFactory"
factory-method="getConfigBean" />
<bean id="dsnBean" factory-bean="ColdboxFactory"
factory-method="getDatasource">
<constructor-arg name="alias">
<value>DBDetails</value>
</constructor-arg>
</bean>
<bean id="userGateway" class="model.Common" />
<bean id="UserService" class="model.UserService">
<property name="dsnBean">
<ref bean="dsnBean" />
</property>
<property name="ConfigBean">
<ref bean="ConfigBean" />
</property>
</bean>
</beans>
I assumed this would allow me to access dns inside common.cfc but it does not.
userservice.cfc
<cfcomponent name="User Service">
<cffunction name="init" access="public" returntype="any"
hint="Constructor.">
<cfreturn this />
</cffunction>
<cffunction name="getUserGateway" access="public" returntype="any"
output="false" hint="Return the UserGateway.">
<cfreturn variables.instance['userGateway'] />
</cffunction>
<cffunction name="setUserGateway" access="public" returntype="void"
output="false" hint="Set the UserGateway.">
<cfargument name="userGateway" type="any" required="true"
hint="UserGateway" />
<cfset variables.instance['userGateway'] =
arguments.userGateway />
</cffunction>
<cffunction name="setDSNBean" access="public" returntype="void">
<cfargument name="DSNBean" type="Any" required="true"/>
<cfset variables.dsn = arguments.DSNBean.getName()>
</cffunction>
<cffunction name="setConfigBean" access="public" returntype="void">
<cfargument name="configBean" type="Any" required="true"/>
<!--- <cfset variables.mailName =
arguments.configBean.getKey("mailUsername")>--->
</cffunction>
</cfcomponent>
I dont know what to do in common.cfc to pull it...
any help/examples on what I need to do here or is my understanding of what I am
doing all wrong? If you were doing this how would you go about it, i learn best
from examples (visual keys)
Thanks
