Overview
Spring Cloud Gateway is a Java API gateway built on Spring Framework 6 and Spring Boot 3 (Java 17). It matches requests by path, method, header or host, then applies filters scoped to the route that modify the downstream request and response, such as header changes, path rewrites and circuit breaker. Routes can be defined in configuration or through an API, and can come from a Spring Cloud DiscoveryClient.
Who it is for: Java teams routing HTTP traffic to microservices on Spring Boot
Strengths
- Routes can be defined in configuration or through a Java API
- Route matching is built into Spring Handler Mapping
- Per-route filters cover headers, parameters, path rewrite and circuit breaker
- Spring Cloud DiscoveryClient can supply routes
Weaknesses
- Requires a JVM (Java 17) and the Spring Boot 3 stack
- README covers only building and contributing, no usage or config examples
- No Docker image or compose file detected in the repository
- Not a model or LLM gateway; no AI features described
What it needs
- no GPU
- Needs JDK 17, Maven, Spring Boot 3, Docker (tests needing Redis)
