Differences between action and methods in Grails controllers

Question

As far as I know, if I want to create an action in a controller then I can do it by:

class My Controller {
    def myAction = {
      println \"in my action \"
          


        

Answer 1

Leveraging methods instead of actions(Closure properties) has some advantages:

1. Memory efficient
2. Allow use of stateless controllers (singleton scope)
3. You can override actions from subclasses and call the overridden superclass method with super.actionName()
4. Methods can be intercepted with standard proxying mechanisms, something that is complicated to do with Closures since they're fields.
