Spring Security authentication with Groovy Grails setup

In this recipe we shall first set up Groovy and Grails. We shall then show how to integrate Spring Security with Grails.

Getting ready

• Get Groovy installed from http://groovy.codehaus.org/Download
• Download Grails 2.3 from http://groovy.codehaus.org/Download and unzip it to a folder
• Set environment variable: GRAILS_HOME
• Check for Groovy_HOME
• Check Grails installation by typing grails-version

How to do it…

The following steps are taken to integrate Spring Security with Groovy Grails:

1. Create a directory: Grails Project.

   cd Grails_Project
   grails create-app myfirstapp
   cd myfirstapp
   grails create-controller MyFirstController
   

   This will create a controller which will be available inside the controller package.

2. You can open the generated controller file and view it. It will have package name myfirstapp which Grails has auto generated.

   package myfirstapp
   class MyFirstController {
       def index() { }
   }

3. Update the generated controller file.

   package myfirstapp...
