AOP / Mailet loading

[Johnny Minty <jo...@minty.net.nz>]

Hi Guys,


When mailets are loaded are they registered as beans within the spring container? 

I intend to use AOP on methods within a mailet however if it is not registered as a spring bean I will need to use load time weaving which I want to avoid if possible.



Kind regards,

Johnny Minty

Hi,

As any mailet can be defined, there is not pre-defined mailet bean in
the spring context.

They are loaded with a MailetLoaderBeanFactory [1].
Maybe you could do some clever things in the MailetLoaderBeanFactory, 
but it will always be acting runtime, the same way load-time weaving acts.

Are you looking on this do avoid any preformance penality?
Once you weave, I'm not sure if Compile or Load time makes a big 
difference (read [2] for example). Weaving vs non-weaving does make the 
difference.

Thx, Eric
