15 Implementing an OAuth 2 resource server

This chapter covers

Implementing a Spring Security OAuth 2 resource server
Using JWT tokens with custom claims
Configuring introspection for opaque tokens or revocation
Implementing more complex scenarios and multitenancy

This chapter discusses securing a backend application in an OAuth 2 system. What we call a resource server in OAuth 2 terminology is simply a backend service. While in chapter 14 you learned how to implement the authorization server responsibility using Spring Security, it’s now time to discuss how to use the token the authorization server generates.

In real-world scenarios, you might or might not implement a custom authorization server like we did in chapter 14. Your organization ...
