SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Centralizes API routing, security, rate limiting, and observability for microservices behind a single entry point.

Core Features & Use Cases

  • Centralized routing to backend services via Spring Cloud Gateway.
  • JWT authentication/authorization and CORS handling.
  • Redis-backed rate limiting and circuit breaking with Resilience4j.
  • Global logging, traceability, and fallback support for degraded services.
  • Easy extension to add new routes and policies.

Quick Start

Run mvn spring-boot:run from the gateway-service module and test endpoints like http://localhost:8080/api/users.

FAQPage Schema
How do I centralize API routing and JWT authentication for Java Spring Boot microservices?▼

Centralizing API routing and JWT authentication for Java Spring Boot microservices is done by deploying a Spring Cloud Gateway. It acts as a single entry point to manage route configuration, validate tokens, and distribute traffic across backend services.

What is the best way to implement rate limiting in a Spring Cloud Gateway?▼

The best way to implement rate limiting in a Spring Cloud Gateway is by using Redis-backed configurations. Redis manages distributed rate limits efficiently, preventing backend microservices from being overwhelmed by excessive client API requests.

How does circuit breaker integration work with Resilience4j in a microservices gateway?▼

Circuit breaker integration with Resilience4j in a microservices gateway monitors backend service calls and trips a breaker when failures exceed a threshold. This provides fallback support and prevents cascading failures across degraded services.

Can I handle CORS and global logging in a Spring Cloud Gateway setup?▼

Yes, you can handle CORS and global logging in a Spring Cloud Gateway setup. The gateway configures Cross-Origin Resource Sharing policies and applies global logging filters to ensure traceability and observability for all routed API traffic.

Do I need Redis to configure fault tolerance for my Spring Cloud Gateway?▼

You need Redis specifically for distributed rate limiting in a Spring Cloud Gateway. For broader fault tolerance, Resilience4j handles circuit breaking and fallback logic, while Redis ensures rate limits are shared across multiple gateway instances.
