Spring Cloud Gateway

This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency.

There are two distinct flavors of Spring Cloud Gateway: Server and Proxy Exchange. Each flavor offers WebFlux and MVC compatibility.

  • The Server variant is a full-featured API gateway that can be standalone or embedded in a Spring Boot application.

  • The Proxy Exchange variant is exclusively for use in annotation based WebFlux or MVC applications and allows the use of a special ProxyExchange object as a parameter to a web handler method.
