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.

How to use it ?

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 :

Authorization Code (response type : token) Flow :

=============== =================================================

Request			GET /oauth/authorize
Request Body    response_type=token&client_id=test&redirect_uri=http://localhost:8080/yourapp
				# Submit the login form with an authorized user
Response Code	302 Found
Redirect to 	http://localhost:8080/yourapp#access_token=7ad8f410-d9d4-4106-b8c2-13cc48c0269d&token_type=bearer&expires_in=42634&scope=read%20write

OAuth2 Token Validation Service

An endpoint that allows a resource server to validate an access token. The application client is authenticated via basic auth for this call.

Request			POST /oauth/check_token
Request Body	token=7ad8f410-d9d4-4106-b8c2-13cc48c0269d
Request Headers Authorization: Basic dGVzdDp0ZXN0 => stands for Base64.encode(client_id:client_secret)
				Content-Type: application/x-www-form-encoded
Response Codes  200 OK
Response Body   ::
                {
				    "exp": 1426391913,
				    "user_name": "userTest",
				    "scope": [
				        "read",
				        "write"

				    "authorities": [
				        "ROLE_USER"
				    ],
				    "client_id": "test"
				}

OpenID User Info Endpoint

An OAuth2 protected resource and an OpenID Connect endpoint. Given an appropriate access_token, returns information about a user.

Request Headers Authorization: Bearer 

Response Codes  200 OK
Response Body   ::
               {
				    "password": null,
				    "username": "userTest",
				    "authorities": [
				        {
				            "authority": "ROLE_USER"
				        }
				    ],
				    "accountNonExpired": true,
				    "accountNonLocked": true,
				    "credentialsNonExpired": true,
				    "enabled": true
				}

Thanks

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