An Overly simplistic ColdSpring Application

This just to get you started on building a basic coldspring application. This topic is beaten to death everywhere else, and I’ve just posted this to do my part in cluttering the web (and to give me a starting point in learning CS). For more documentation go here.

An example of a simple Coldspring application that has a USER bean and a USERSERVICE class.

 

 

 

The Application.cfc file:

   1: <!--- Run when application starts up --->

   2:     <cffunction name="onApplicationStart" returnType="boolean">

   3:         <cfset default_properties = structNew() />

   4:         <cfset default_properties['default_username'] = "Anang" />

   5:         

   6:         <cfset coldspringConfig = 'config/coldspring.xml' />  

   7:         <cfset beanFactory = CreateObject('component', 'coldspring.beans.DefaultXmlBeanFactory').init(defaultproperties=default_properties) />  

   8:         <cfset beanFactory.loadBeans(coldspringConfig) />         

   9:         

  10:         <cfset userService = beanFactory.getBean('userService') />       

  11:         

  12:         <cfreturn true />

  13:     </cffunction>

The ColdSpring XML file:

   1: <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

   2: <beans>

   3:     <bean id="user" class="LearnCS.app.user.UserBean">

   4:         <property name="Username">

   5:             <value>${default_username}</value>

   6:         </property>

   7:     </bean>

   8:     

   9:     <bean id="userService" class="LearnCS.app.UserService">

  10:         <property name="user">

  11:             <ref bean="user"/>

  12:         </property>

  13:     </bean> 

  14: </beans>

The User bean and UserService class

   1: <cfcomponent name="User Bean">

   2:     <cfset variables._username = "" />

   3:     

   4:     <cffunction name="init">

   5:         <cfreturn this />

   6:     </cffunction>

   7:     

   8:     <cffunction access="public" returntype="String" name="getUsername">

   9:         <cfreturn variables._username />

  10:     </cffunction>

  11:     

  12:     <cffunction access="public" returntype="void" name="setUsername">

  13:         <cfargument name="username" type="String" required="true" />

  14:         <cfset variables._username = arguments.username />

  15:     </cffunction>

  16: </cfcomponent>

  17:  

  18:  

  19: <cfcomponent name="User Service">

  20:     <cfset variables._instance = structNew() />

  21:     <cffunction name="init">

  22:         <cfreturn this />

  23:     </cffunction>

  24:     

  25:     <cffunction access="public" returntype="LearnCS.app.user.UserBean" name="getUser">

  26:         <cfreturn variables._instance["user"] />

  27:     </cffunction>

  28:     

  29:     <cffunction access="public" returntype="void" name="setUser">

  30:         <cfargument name="userBean" type="LearnCS.app.user.UserBean" required="true" />

  31:         

  32:         <cfset variables._instance["user"] = arguments.userBean />

  33:     </cffunction>

  34: </cfcomponent>
