Demo using JWT in Spring Security

This app demonstrates standalone JWT authorization in Spring Security using OAuth 2.0 Resource Server feature.

Actually it mimics OAuth2's Resource Owner Password Credentials flow.

ACCESS_TOKEN=$(curl -s localhost:8080/oauth/token -d grant_type=password -d username=demo -d password=demo | jq -r .access_token)

TODO_ID=$(curl -s localhost:8080/todos -H "Authorization: Bearer ${ACCESS_TOKEN}" -H "Content-Type: application/json" -d '{"todoTitle": "Demo"}' | jq -r .todoId)
curl -s localhost:8080/todos -H "Authorization: Bearer ${ACCESS_TOKEN}"
curl -s localhost:8080/todos/${TODO_ID} -H "Authorization: Bearer ${ACCESS_TOKEN}"
curl -s -X PUT localhost:8080/todos/${TODO_ID} -H "Authorization: Bearer ${ACCESS_TOKEN}" -H "Content-Type: application/json" -d '{"finished": "true"}'
curl -s -X DELETE localhost:8080/todos/${TODO_ID} -H "Authorization: Bearer ${ACCESS_TOKEN}"
curl -s localhost:8080/todos -H "Authorization: Bearer ${ACCESS_TOKEN}"
