Keycloak can serve this use-case pretty well. Once you authenticate
application1 with Keycloak, you will receive accessToken for this
application. This accessToken can then be used to invoke other HTTP
services (like "application2") and retrieve data from them. You just
need to send the obtained accessToken in Authorization header in format
like "Authorization: Bearer your-token".
Also if your application "application2" is used just as "container of
REST data" for other applications and never accessed directly by user
from his browser, you can configure at as "bearer-only" in keycloak
admin console and in keycloak.json of this application.
We have examples exactly for this usecase: "customer-service" uses
accessToken to invoke bearer-only application "database-service" and
obtain data from it. See code here:
