Transfer and coldspring

[Chris Blackwell]

Hi

I have transfer setup up in my applications coldspring, and i'm wondering whether its ok to ask cs to create an instance of transfer.com.Transfer using the factory-bean/factory-method attributes, rather than having to do transferFactory.getTransfer() everywhere.  I have the following bean definitions for transfer

<beans>   
   
    <bean id="transferConfiguration" class="transfer.com.config.Configuration">
        <constructor-arg name="datasourcePath"><value>/config/transfer/Datasource.xml</value></constructor-arg>
        <constructor-arg name="configPath"><value>/config/transfer/Transfer.xml</value></constructor-arg>
        <constructor-arg name="definitionPath"><value>/model/data</value></constructor-arg>
    </bean>
   
    <bean id="transferFactory" class="transfer.TransferFactory">
        <constructor-arg name="configuration"><ref bean="transferConfiguration" /></constructor-arg>
    </bean>

    <bean id="transfer" class="transfer.com.Transfer"
        factory-bean="transferFactory"
        factory-method="getTransfer">
    </bean>

</beans>

Is that a reasonable way to go ?

cheers, Chris

Absolutely. Transfer is still used by most applications as a
singleton, so having CS respond to getBean("Transfer") is a perfectly
viable (and even recommended) approach to having a ColdSpring managed
way of getting to Transfer.

In this role, Transfer is acting as a factory to access your domain
objects.

Chris,

Absolutely.  I would also recommend bean definitions for...

<bean id="datasource" factory-bean="transferFactory" factory-method="getDatasource" />
   
<bean id="transaction" factory-bean="transferFactory" factory-method="getTransaction" />

And while you're at it, you may want to add:

<bean id="TDOBeanInjectorObserver"
class="path.to.TDOBeanInjectorObserver" lazy-init="false">
<constructor-arg name="transfer"><ref bean="transfer" /></constructor-arg>
<constructor-arg
name="afterCreateMethod"><value>Setup</value></constructor-arg>
<property name="beanInjector">
<ref bean="beanInjector" />
</property>
</bean>

<bean id="beanInjector" class="path.to.BeanInjector">
<constructor-arg name="debugMode"><value>false</value></constructor-arg>
</bean>

Which will allow your Transfer Objects to be autowired via Brian's
BeanInjector (http://coldspringutils.riaforge.org/). It may seem a
bit complicated at first, but you'll probably find you need it
eventually.
