Dynamic lookup performance

[nestorjb]

Hi

I would like to know the performance of using dynamic lookup. For example I'm using spring to configure my loggers and I don't know if I should lookup the loggers once and then access them with local variables, or use dynamic lookup in every logger call.

Regards,

You mean getBean() every call? I would not recommend that, not only on performance grounds but because it means that lots of your code explicitly knows about Spring. Method injection would get around that objection, but will definitely have a cost.

Hi

In my case I can't using Ioc because I'm looking up the loggers from struts. I'm using Spring extensions for struts but in my action classes I need to lookup the loggers.
