(Quick Reference) ## scope ### Purpose Changes the scope of a controller ### Examples
    class BookController {

        static scope = "session"

        // ...
    }
### 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. | Quick Reference (hide)
