Resource Server Setup
Configure a Spring Boot application as an OAuth2 Resource Server to protect its API endpoints.
What is a Resource Server?
Welcome to configuring a Spring Security OAuth2 Resource Server! This is a crucial component in modern secure applications.
- A Resource Server hosts protected resources, like your API endpoints.
- It receives access tokens from clients and validates them.
- If a token is valid, it grants access to the requested resource.
Think of it as the bouncer at a club, checking tickets (access tokens) before letting anyone in.
Role in OAuth2 Flow
In the OAuth2 flow, the Resource Server works hand-in-hand with an Authorization Server.
- The client first gets an access token from the Authorization Server.
- Then, the client sends this token to the Resource Server when requesting a protected resource.
- The Resource Server doesn't issue tokens; it only validates them.
This separation of concerns makes your application more secure and scalable.
