title: Oauth2 authentication with Spring boot
body: <p>Hi I am really new to Spring boot and Oauth2. I need to understand how to authenticate Spring boot web service with Oauth2 authentication with refresh token and access tokens. Likewise I need to know how to limit the access of different users (accessing resources) dynamically as well. I have searched in many articles on line and ended up with nothing that I really need to learn. I do not need SSO config with facebook or google. I want to know how to make our own authorization server.</p>
  
  <p>Can anybody please help me to guide or send me a link of a useful tutorial that helps me to learn.</p>
  
  <p>thank you.  </p>
