Demonstrates using Auth0 with Grails 2 to create a Secured MVC Web Application

Demonstrates using Auth0 with Grails 2 to create a Secured MVC Web Application

This is a companion sample for the Auth0 Spring MVC library. Please refer to that library and documentation for further information specific to the library itself.

Allows you to use Auth0 with Grails 2 in order to create a server-side MVC web apps. Leverages Spring Boot dependencies internally. Validates the JWT from Auth0 in every API call to assert authentication according to configuration. If your application only needs secured endpoints and the ability to programmatically work with a Principal object for GrantedAuthority checks this library is a good fit.

However, if you are already using Java Spring and wish to leverage fully Java Spring Security - with powerful support for Security Annotations, Security JSTL Tag libraries, Fine-grained Annotation level method security and URL endpoint security at the Role / Group level - then see this project Auth0 Spring Security MVC and associated sample Auth0 Spring Security MVC Sample

Please note, we are currently working on Grails Samples to illustrate integration with the Auth0 Spring Security libraries.

Prerequisites

In order to run this example you will need to have Java 7+, and Grails 2 installed.

Check the Grails documentation for details on installing Grails 2. sdkman is one useful tool for this purpose.

Check installed successfully with:

grails --version

FYI only, in creating this sample, the following SDK versions were used:

Grails version: 2.4.5
Groovy Version: 2.4.7
JVM Version: 1.8.0_77

Setup

Create an Auth0 Account (if not already done so - free!).

From the Auth0 Dashboard

Create an application - for the purposes of this sample - app

Ensure you add the following to the settings.

Allowed Callback URL:

http://localhost:3099/callback

Ensure you add the following to the settings.

Allowed Logout URLs:

http://localhost:3099/logout

Add one or more connections to your application - for instance Google Social Connection, or username-password DB connection.

Inside the Application - update configuration information

Enter your:

client_id, issuer, client_secret, and domain information into grails-app/conf/auth0.properties

An example of populated values is shown below (please use your own values):

auth0.domain: arcseldon.auth0.com
auth0.issuer: https://arcseldon.auth0.com/
auth0.clientId: 7JbjgoK7BAuLL4AL6x8pOYfNSiBeZMdW
auth0.clientSecret: dn0p_95MmZKMDoXXXXXXXkE5Uu1Opo9oXXXXaho03P9Q907oHUE

Please note that the configuration for the secured is located inside src/templates/war/web.xml

 <filter>
    <filter-name>auth0Filter</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter>
<filter-mapping>
    <filter-name>auth0Filter</filter-name>
    <url-pattern>/portal/*</url-pattern>
</filter-mapping>

Build and Run

In order to build and run the project execute:

grails run-app

Then, go to http://localhost:3099/.

The Gradle landing page has been left with the sample so you can see the Controllers used, and get general information on the Grails application itself. Since it launches from the root URL it is unsecured and hence available on startup.

To login, go to http://localhost:3099/login - you can click on the LoginController link if you like.
