Spring Cloud Feign + OAuth 2.0

This is an example of Spring Cloud Feign and Spring Security OAuth2.

API server
- Spring Boot web server running on port 8081
- Enable request logging (CommonsRequestLoggingFilter)
- Enable OAuth authorization server
- Enable OAuth resource server
- Configure OAuth client ID and secret
- Configure resource owners (theUser1 and theUser2)
- Example REST controller
API client (CLI)
- Spring Boot without web server
- Enable OAuth client access token request logging
- Enable Feign client logging
- Enable Feign client
- Disable Hystrix
- Enable Feign request interceptor for OAuth 2.0 client (OAuth2FeignRequestInterceptor)
- Example REST client for the API server using resource owner password grant
- Example REST client for Twitter API using client credentials grant
API client (web)
- Spring Boot web server running on port 8082
- Enable request logging (CommonsRequestLoggingFilter)
- Enable OAuth client access token request logging
- Enable Feign client logging
- Enable Feign client
- Disable Hystrix
- Enable Feign request interceptor for OAuth 2.0 client (OAuth2FeignRequestInterceptor)
  - Use Client Credentials Grant if not logged in
  - Use Resource Owner Password Grant if logged in
- Configure to renew session on login
- Example REST client for the API server using resource owner password grant
- Example REST client for Twitter API using client credentials grant

Run the client CLI

./gradlew server:bootRun

./gradlew client-cli:bootRun

API client does:

Acquire an access token from the API server
Send a request with the access token to the API server
Acquire an access token from Twitter API
Send a request with the access token to Twitter API

API client:
