Spring REST Service OAuth

This is a simple REST service built using Spring Boot, Spring MVC, Spring Security and Spring Security OAuth that provides a single RESTful endpoint protected by OAuth2. The REST service is based on the Building a RESTful Web Service getting started guide. This project is built using the new Java-based configuration support, now available in Spring Security OAuth 2.0. Please log any issues or feature requests to the Spring Security OAuth project.

Build and Run

Use Gradle:

./gradlew clean build bootRun

Or use Maven:

mvn clean package spring-boot:run

Usage

Test the greeting endpoint:

curl http://localhost:8080/greeting

You receive the following JSON response, which indicates you are not authorized to access the resource:

{
  "error": "unauthorized",
  "error_description": "An Authentication object was not found in the SecurityContext"
}

In order to access the protected resource, you must first request an access token via the OAuth handshake. Request OAuth authorization:

curl -X POST -vu clientapp:123456 http://localhost:8080/oauth/token -H "Accept: application/json" -d "password=spring&username=roy&grant_type=password&scope=read%20write&client_secret=123456&client_id=clientapp"

A successful authorization results in the following JSON response:

{
  "access_token": "ff16372e-38a7-4e29-88c2-1fb92897f558",
  "token_type": "bearer",
  "refresh_token": "f554d386-0b0a-461b-bdb2-292831cecd57",
  "expires_in": 43199,
  "scope": "read write"
}

Use the access_token returned in the previous request to make the authorized request to the protected endpoint:

curl http://localhost:8080/greeting -H "Authorization: Bearer ff16372e-38a7-4e29-88c2-1fb92897f558"

If the request is successful, you will see the following JSON response:

{
  "id": 1,
  "content": "Hello, Roy!"
}

After the specified time period, the access_token will expire. Use the refresh_token that was returned in the original OAuth authorization to retrieve a new access_token:

curl -X POST -vu clientapp:123456 http://localhost:8080/oauth/token -H "Accept: application/json" -d "grant_type=refresh_token&refresh_token=f554d386-0b0a-461b-bdb2-292831cecd57&client_secret=123456&client_id=clientapp"
