Spring Cloud Gateway 4.0.6

This project provides a library for building an API Gateway on top of Spring WebFlux. 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.

Features

Spring Cloud Gateway features:

Built on Spring Framework 5, Project Reactor and Spring Boot 2.0

Able to match routes on any request attribute.

Predicates and filters are specific to routes.

Circuit Breaker integration.

Spring Cloud DiscoveryClient integration

Easy to write Predicates and Filters

Request Rate Limiting

Path Rewriting

@SpringBootApplication
public class DemogatewayApplication {
	@Bean
	public RouteLocator customRouteLocator(RouteLocatorBuilder builder) {
		return builder.routes()
			.route("path_route", r -> r.path("/get")
				.uri("http://httpbin.org"))
			.route("host_route", r -> r.host("*.myhost.org")
				.uri("http://httpbin.org"))
			.route("rewrite_route", r -> r.host("*.rewrite.org")
				.filters(f -> f.rewritePath("/foo/(?<segment>.*)", "/${segment}"))
				.uri("http://httpbin.org"))
			.route("hystrix_route", r -> r.host("*.hystrix.org")
				.filters(f -> f.hystrix(c -> c.setName("slowcmd")))
				.uri("http://httpbin.org"))
			.route("hystrix_fallback_route", r -> r.host("*.hystrixfallback.org")
				.filters(f -> f.hystrix(c -> c.setName("slowcmd").setFallbackUri("forward:/hystrixfallback")))
				.uri("http://httpbin.org"))
			.route("limit_route", r -> r
				.host("*.limited.org").and().path("/anything/**")
				.filters(f -> f.requestRateLimiter(c -> c.setRateLimiter(redisRateLimiter())))
				.uri("http://httpbin.org"))
