Is there a way to reload all controllers?

[gatherer]

I have defined some parameters in config.groovy, and access them from some controllers. I'd like to be able to change the parameters on the fly in config.groovy to modify the controllers behavior without having to manually edit those controllers or restart the server. But the controllers aren't reloaded and see the old values that were in config.groovy when the server started.

Is there any way to force them to reload (all at once if possible)?

There are a couple of plugins that can help with this,
http://grails.org/plugin/external-config-reload appears to be the more
recently updated.

I don't know if I'm missing something, but I can't see how to reload all the controllers with this plugin.

You shouldn't need to "reload" the controllers as such.  The plugin
watches for changes to your external configuration files, and when any
of them change it re-reads them and updates the grailsApplication.config
to match.  So any code in your controllers that reads
grailsApplication.config.foo.bar will see the updated values.  And since
controllers are (by default) prototype scoped, a new instance is created
for each request and any non-static initialization code will see the
latest values.

I believe it works with non-prototype scoped artefacts as well such as services, etc.  At least that's the way I designed it :)

Does this mean scaffolded controllers will be regenerated too?

[bksaville]

The controllers do not need to be reloaded - the configuration in
grailsApplication.config (a central location) simply gets updated and the
exact same controllers will get the new configuration the next time they
use grailsApplication.config.

Hopefully that helps to clear it up.
