Spring Boot 2.0 OAuth2 JWT example (incl. Auth server & Resource server) in Kotlin

This example makes use of in-memory client credentials and a symmetric signing key shared between both the Auth & Resource servers.

Getting Started

Start up both the applications:

1. ./gradlew :auth-server:bootRun
2. ./gradlew :resource-server:bootRun

Getting a token

Once they have both started, first make a request to the Auth server to get a JWT.

curl http://UserOne:Password@localhost:8080/oauth/token -d grant_type=client_credentials -d scope=write

curl http://UserTwo:Password@localhost:8080/oauth/token -d grant_type=client_credentials -d scope=read

Using the token to access a Resource

Using the access_token you received back from the Auth server, now make the call to the Resource server replacing [TOKEN].

curl http://localhost:8081/resource -H"Authorization: Bearer [TOKEN]"

curl -X POST http://localhost:8081/resource -H"Authorization: Bearer [TOKEN]"
