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:
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"
SSL
To configure the project to run on HTTPS as shown in Building REST services with Spring, enable the https
profile. You can do this by uncommenting the appropriate line in the application.properties file of this project. This will change the server port to 8443
. Modify the previous requests as in the following command.
curl -X POST -k -vu clientapp:123456 https://localhost:8443/oauth/token -H "Accept: application/json" -d "password=spring&username=roy&grant_type=password&scope=read%20write&client_secret=123456&client_id=clientapp"
The -k
parameter is necessary to allow connections to SSL sites without valid certificates or the self signed certificate which is created for this project.
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:
curl http://rclarkson-restoauth.cfapps.io/greeting
