Spring Cloud Gateway MVC: Built for Java 21 and Virtual Threads

Track: Frameworks

Abstract

We will provide a brief history of API gateways in Spring Cloud, including Zuul and why we built Spring Cloud Gateway to replace it. Then we will give a short primer on how the gateway routes and filters requests. We will then introduce how Spring Cloud Gateway can work in servlet containers using virtual threads on Java 21. We will compare and contrast this new functionality to the original WebFlux-based Spring Cloud Gateway.
