Autowiring + Factory Method

[Rawlins]

Hello Guys,

I'm a keen user of LogBox - I have it running several ColdBox/WireBox applications, however I'm now looking to implement it with a ColdSpring based project.

The logbox library implements a kind of factory method (at least that's what I gather) in which you access the given loggers like logbox.getLogger('name.of.logger');

When used in conjunction with Wirebox, you can use a specific DSL to have given loggers injected into service, rather than the actual logbox instance.

For instance in one of my services I can put something like this:

property name="logger" inject="Logbox:Logger:name.of.logger";

This then injects the specific logger from the logger factory method. This saves me having to define each logger separately in the framework config, I need only define the factory and the auto-wire is smart enough to know how to use it.

Can I do something similar to this with ColdSpring? I've not seen it mentioned anywhere before.

Thanks.

Robert

I've never used logbox, but if you have a bean for the logbox factory, you can create a singleton instance of a specific logger by doing

<bean id="LogBox" class="coldbox.system.logging.LogBox" />

<bean id="MyLogger" factory-bean="LogBox" factory-method="getLogger">

  <constructor-arg name="category"><value>name.of.logger</value></constructor-arg>

</bean>

then inject MyLogger into whatever you need.

Thanks Chris,

That's certainly an option, given the number on classes that could be generated by the factory that would still be quite verbose from an XML standpoint - which is why I was keen to find some form of autowire description that could do the same job.

Thanks.

Sounds like something we may need to look at when we tackle annotations.
