For some usages of the gateway, properties will be adequate, but some production use cases will benefit from loading configuration from an external source, such as a database. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories such as: Redis, MongoDB and Cassandra.

7.1 Fluent Java Routes API

To allow for simple configuration in Java, there is a fluent API defined in the Routes class.

-                .and()
-            .route("test2")
                 .uri("http://httpbin.org:80")

                 .predicate(path("/image/webp"))
                 .add(addResponseHeader("X-AnotherHeader", "baz"))
-                .and()

+            .route("test3")
+                .order(-1)
+                .predicate(host("**.throttle.org").and(path("/get")))
+                .add(throttle.apply(tuple().of("capacity", 1,
+                     "refillTokens", 1,
+                     "refillPeriod", 10,

+                .uri("http://httpbin.org:80")
             .build();
 }

This style also allows for more custom predicate assertions. The predicates defined by RouteDefinitionLocator beans are combined using logical and. By using the fluent Java API, you can use the and(), or() and negate() operators on the Predicate class.

10. Building a Simple Gateway Using Spring MVC

Spring Cloud Gateway provides a utility object called ProxyExchange which you can use inside a regular Spring MVC handler as a method parameter. It supports basic downstream HTTP exchanges via methods that mirror the HTTP verbs, or forwarding to a local handler via the forward() method.

Example (proxying a request to "/test" downstream to a remote server):
