OAuth2 Authorization Server based on Spring Security OAuth2

This is a basic Authorization server based on Spring Security OAuth2.

The main goal is to show you how to implement an Authorization Server with Spring Security OAuth2.

Checkout the OAuth2 Authorization Server :

- git clone https://github.com/tcompiegne/oauth2-server.git
- mvn install

Start the server :

  mvn jetty:run

Get your tokens :

Many thanks to the Spring Team and particularly Dave Syer for their job to make easy to understand and set up oauth2 infrastructure.
