class BookController {
static scope = "session"
// ...
}
scope
Purpose
Changes the scope of a controller
Examples
Description
Unless specified by the grails.controllers.defaultScope
property in application.yml
, controllers by default are "singleton" scoped which means that only one instance of the controller exists.
This behaviour can be set for an individual controller by specifying a scope
attribute with one of the following values:
-
singleton
(default) - Only one instance of the controller ever exists (recommended for actions as methods) -
prototype
- A new controller will be created for each request (recommended for actions as Closure properties) -
session
- One controller is created for the scope of a user session
See Controllers and Scopes in the user guide for more information.
