Spring REST Service OAuth

This is a simple REST service that provides a single RESTful endpoint protected by OAuth 2. The REST service is based on the Building a RESTful Web Service getting started guide. This project incorporates 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.

Spring Projects

The following Spring projects are used in this sample app:

• Spring Boot
• Spring MVC
• Spring Security
• Spring Security OAuth
• Spring Data JPA

Build and Run

Use Gradle:

./gradlew clean build bootRun

Or 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"

Cloud Foundry Demo

The service is deployed to Pivotal Cloud Foundry and available for testing. Modify the previous commands to point to the following URL:
