add-gateway

What problem does it solve?

This Skill eliminates the time-consuming setup of an enterprise API gateway by providing a proven blueprint for routing requests and centralizing JWT authentication in a separate Spring Boot gateway project.

Core Features & Use Cases

• Gateway project scaffolding for infrastructure: Creates a standalone Spring Cloud Gateway MVC application with its own build, deployment unit, and routing configuration distinct from domain services.
• JWT validation and identity propagation: Validates JWT at the gateway and forwards authenticated identity downstream via trusted headers for consistent authorization without duplicating JWT validation.
• Spec-driven routing and operational health: Implements path-based routing (e.g., /api/users/, /api/payments/), includes gateway-level health aggregation patterns, and enforces a servlet/WebMvc-compatible test approach.
• Use Case: When you have multiple Spring Boot services and need a single entry point for a frontend, use this Skill to route traffic, validate tokens once, and pass user identity to backend services.

Quick Start

Create a new separate gateway Spring Boot project alongside your domain services, then apply the route configuration, gateway security configuration, identity propagation, and downstream trust filter pattern described in this Skill.
