grails create-controller org.bookstore.helloController Usage
A controller fulfills the C in the Model View Controller (MVC) pattern and is responsible for handling web requests. In Grails a controller is a class with a name that ends in the convention "Controller" and lives in the grails-app/controllers directory. A controller can be created with the create-controller command:
or with your favourite IDE or text editor.
package org.bookstore
class HelloController {
def world() {
render "Hello World!"
}
}Each action in the controller is a method or a Closure and it has access to a number of implicit variables and methods.
