Spring Boot JWT Authorization and Resource Server

---

Run them

Start authorization server:

cd authorization-server
./gradlew bootRun

Start resource server:

cd ..
cd resource-server
./gradlew bootRun

Both Spring projects have their application.properties files checked-in for simplicity. You can change the ports there. If unchaged the authorization server will run on localhost:8080 and the resource server will run on localhost:8081.

Retrieve JWT token:

curl -X POST -u "testClient:testClientSecret" -d "grant_type=password&username=testUser&password=testUserPassword" http://localhost:8080/oauth/token

Consume secured REST API:

curl -X GET -H 'Authorization:Bearer [JWT_TOKEN]'  http://localhost:8081/hello

This is mostly based on this great Baeldung article:

I ported this example with slight modifications to Kotlin.
