This sample demonstrates integrating Resource Server with a mock Authorization Server, though it can be modified to integrate with your favorite Authorization Server. This resource server is configured to accept JWE-encrypted tokens.
With it, you can run the integration tests or run the application as a stand-alone service to explore how you can secure your own service with OAuth 2.0 Bearer Tokens using Spring Security.
To run the tests, do:
./gradlew integrationTest
Or import the project into your IDE and run OAuth2ResourceServerApplicationTests
from there.
By default, the tests are pointing at a mock Authorization Server instance.
The tests are configured with a set of hard-coded tokens originally obtained from the mock Authorization Server, and each makes a query to the Resource Server with their corresponding token.
The Resource Server decrypts the token and subsquently verifies it with the Authorization Server and authorizes the request, returning the phrase
Hello, subject!
where "subject" is the value of the sub
field in the JWT returned by the Authorization Server.
To run as a stand-alone application, do:
./gradlew bootRun
Or import the project into your IDE and run OAuth2ResourceServerApplication
from there.
Once it is up, you can use the following token:
export TOKEN=eyJjdHkiOiJKV1QiLCJlbmMiOiJBMjU2R0NNIiwiYWxnIjoiUlNBLU9BRVAtMjU2In0.IyeWtsTonaiWJdoT13B0M7gpqVxAirVGlfqFI4TOmTRcVHICs_ESezS7fa0ODS9XYdwklTtG7hH39yeeMzr2Zo1Ghh-m36fdoqQrV1Do04rUvuTjqbgyNffeZEGB6rquJ-cyAVjp_Oljy10-Bbnw7CeVGwNBSVo9UCB5j49OlNWhLxFpYARFmOlYpXj-s4Q4JiqV6EvjDAYeohAR4QQmND3qoxR-s2I6SLcIho0sSSpUlhrRiqu2uvWefHDcZJdW2WYWnxLHxhzNu3CfnLiqhhaA_YA_iWXR9FYnPDCf_4q3FgSXcgttXzomFKAx5DwnE_dXvsCvpWxslZMU1UIiLA.MHOrrza2GQ9_5PIv.zU4tfhxT6apWBC3stBwQmGlCQBltWVQe4dFIykybWWBFqxo1bf2BZ37twzoEIFXG9jSYEMH4mvBXPWSvn66t-_jnqLnKTJst2plBjhagGCAoLNWXVKeYNp67o-lKOD_JJQFqsRw4oE05VSgRr14MZeaUBFcU3A_kKxMXOu899DKfXBGJvj75H7lDyd8RUXTb-OSWWfUiJc6Y5AUy1zCZCN9yfDsCXt9heTsZANy92Oou9sMFaXkYzyums5OtkBtLFzyuNMEoNioRehTV-FTuL8tDRB1mNhHObwsBfFbR6M1jJK37pHUXGtko-yZ6NGwxyLtwGh4uU2jzE614rQzuzR8aHaHxOkUs1pBTZ8AcRt41snByOe-KU0adthHxedobFiQQBoQ05DgSU7DO6hsK0uVBDF3eG2KjH4L2lZy-WugloLHhdguUoO9F0zUx15-XZO4EVzmhy8xfH2tSXz98eKzz9Dv0DdGnrBL9cK2MM88N1zoq5u4NdlnE12HvuesB7GKdMwZx1-gTw_pzP81TzcctJWl6ETK09Uc.jk0O8qc4Fvip856stDz05Q
And then make this request:
curl -H "Authorization: Bearer $TOKEN" localhost:8080
Which will respond with the phrase:
Hello, subject!
where subject
is the value of the sub
field in the JWT returned by the Authorization Server.
Or this:

Will respond with:
secret message
In order to use this sample, your Authorization Server must encrypt using the public key available in the sample. Also it must support JWTs that either use the "scope" or "scp" attribute.
To change the sample to point at your Authorization Server, simply find this property in the application.yml
:
spring:
security:
oauth2:
resourceserver:
jwt:
jwk-set-uri: ${mockwebserver.url}/.well-known/jwks.json
And change the property to your Authorization Server’s JWK set endpoint:
spring:
security:
oauth2:
resourceserver:
jwt:
jwk-set-uri: https://localhost:9031/pf/JWKS
If your Authorization Server does not support RSA_OAEP_256 or AESGCM, then you can change these values in OAuth2ResourceServerSecurityConfiguration
:
And then you can run the app the same as before:
./gradlew bootRun
Make sure to obtain valid tokens from your Authorization Server in order to play with the sample Resource Server.
To use the /
endpoint, any valid token from your Authorization Server will do.
To use the /message
endpoint, the token should have the message:read
scope.
