SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Spring Boot applications often need to securely validate and authorize requests using JWTs from external identity providers. This skill standardizes the integration pattern for OAuth2 resource servers, reducing boilerplate and misconfigurations.

Core Features & Use Cases

Validate JWTs against a configured issuer and JWKS endpoint.
Map user roles/claims to application permissions and enforce scope-based access.
Support popular providers like Keycloak, Auth0, Okta, and Cognito with customizable claim extraction.
Use case: Protect REST APIs and admin endpoints, while exposing health endpoints publicly.

Quick Start

Configure Spring Security as a JWT-based OAuth2 resource server and test with a sample token.

FAQPage Schema

How do I configure a Spring Boot OAuth2 resource server to validate JWTs?▼

To configure an OAuth2 resource server in Spring Boot, you enable Spring Security to validate JWTs against a configured issuer and jwk-set-uri. This standardizes integration and reduces boilerplate misconfigurations.

Can I use Spring Security OAuth2 resource server with Keycloak, Auth0, Okta, or Cognito?▼

Yes, Spring Security OAuth2 resource server setups support popular providers like Keycloak, Auth0, Okta, and Cognito. It allows customizable claim extraction to map user roles from any of these external platforms.

How do I enforce scope-based access control for REST APIs using JWT claims?▼

You enforce scope-based access by mapping JWT claims to application permissions within Spring Security. This protects REST API routes while allowing you to expose specific endpoints like health checks publicly.

What is the best way to protect admin endpoints while exposing health endpoints in Spring Boot?▼

The best way to protect admin endpoints is configuring Spring Security as a JWT-based OAuth2 resource server. This validates tokens for admin routes while allowing you to explicitly expose health endpoints publicly without authentication.

Do I need a custom claim extraction strategy for OAuth2 JWT validation in Spring Boot?▼

You need a custom claim extraction strategy if your identity provider uses non-standard JWT claims. This mapping strategy allows Spring Security to correctly translate user roles into enforceable application permissions.
