Spring Cloud Gateway is intended to sit between a requester and a resource that's being requested, where it intercepts, analyzes, and modifies every request. The expected return is a Publisher of instances of the informed out-class. To write a custom global filter, you must implement GlobalFilter interface. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. We use constructor injection to get an instance of this factory, and in apply(), we delegate to it the task of creating a GatewayFilter instance. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. The following listing configures a LoadBalancerClientFilter: The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. SCG already has several utility classes that we can use to implement this factory. The resulting response is similar to the following: The response contains the details of the GatewayFilter factories applied to any particular route. It consists of ID destination URI Collection of predicates and a collection of filters A route is matched if aggregate predicate is true. This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer. to the exchange attributes. To enable this, set spring.cloud.gateway.discovery.locator.enabled=true and make sure a DiscoveryClient implementation (such as Netflix Eureka, Consul, or Zookeeper) is on the classpath and enabled. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments. status: The HTTP status of the request returned to the client. This is the number of tokens taken from the bucket for each request and defaults to 1. should also work without issue as long as they use Maven 3.3.3 or better. 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. The following listing configures a RedirectTo GatewayFilter: This will send a status 302 with a Location:https://acme.org header to perform a redirect. Active contributors might be asked to join the core team, and This approach is vulnerable to spoofing, as a malicious client could set an initial value for the X-Forwarded-For, which would be accepted by the resolver. In order to write a Route Predicate you will need to implement RoutePredicateFactory. By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. In configuration, you can reference the bean by name using SpEL. The preceding route matches if the request contained a red query parameter whose value matched the gree. response-timeout must be specified as a java.time.Duration. 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. After the proxy request is made, the post filter logic is run. This is useful when you try to support CORS preflight requests and your route predicate does not evalute to true because the HTTP method is options. Spring Cloud Gateway is mainly used in one of the following roles: OAuth Client. Building a Simple Gateway by Using Spring MVC or Webflux, FallbackHeaders GatewayFilter Factory section, Spring Cloud CircuitBreaker Factory section, object-service.prod.example.net/v2/some/object/id, Retrieving Information about a Particular Route. It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. URI variables may be used in the value and are expanded at runtime. httpMethod: The HTTP method used for the request. This is the value of the Location header. Apache, Apache Tomcat, Apache Kafka, Apache Cassandra, and Apache Geode are trademarks or registered trademarks of the Apache Software Foundation in the United States and/or other countries. The args key is a map of key value pairs to configure the predicate or filter. sign in You can configure the logging system to have a separate access log file. Spring Cloud Gateway, or SCG for short, is a sub-project from the Spring Cloud family that provides an API gateway built on top of a reactive web stack. The following example shows how to achieve the same configuration with Java: Route filters allow the modification of the incoming HTTP request or outgoing HTTP response in some manner. marketplace". The following listing configures a RequestSize GatewayFilter: The RequestSize GatewayFilter factory sets the response status as 413 Payload Too Large with an additional header errorMessage when the request is rejected due to size. Instead, this time well focus on a particular usage scenario that arises from time to time when designing a solution around an API Gateway: how to process a backend response payload before sending it back to the client? For relative redirects, you should use uri: no://op as the uri of your route definition. We can route that request to the appropriately versioned backend. to contribute even something trivial please do not hesitate, but XForwardedRemoteAddressResolver has two static constructor methods, which take different approaches to security: XForwardedRemoteAddressResolver::trustAll returns a RemoteAddressResolver that always takes the first IP address found in the X-Forwarded-For header. The Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). Fully expanded arguments appear more like standard yaml configuration with name/value pairs. that on it will try to build asciidoc sources from Project defaults for Intellij that apply most of Checkstyle rules, Project style conventions for Intellij that apply most of Checkstyle rules. Request Rate Limiting. Spring Cloud Gateway is API Gateway implementation by Spring Cloud team on top of Spring reactive ecosystem. Introduction. 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. Spring Cloud supports Resilience4J out of the box. This filter adds a timer metric named gateway.requests with the following tags: routeUri: The URI to which the API is routed. Its implementation just walks recursively over all nodes, looking for attributes that match the configured pattern and replacing the corresponding value for the mask: Weve included two tests in the example code: a simple unit test and an integration one. youre working on spring-cloud-contract. The following listing configures a ReactiveLoadBalancerClientFilter: The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. See the documentation for @RequestMapping in Spring MVC for more details of those features. Basically, the spring boot gateway provides a simple and effective way to route API's. This strips the service ID from the path before the request is sent downstream. Also important is the fact that this configuration is a ModifyResponseBodyGatewayFilterFactory one. It adds the Host header, scheme and port of the current request to any existing Forwarded header. Creating and Deleting a Particular Route, 17.1. It takes stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. While working with integration tests, hit the gateway service that is started on the endpoint, seeing the requests forwarded to respective services, I was wondering if there is a good practice to test this Spring Cloud Gateway feature. This class comes from the Jackson library and is at the very top of the hierarchy of classes used to represent different node types in JSON, such as object nodes, array nodes, and so forth. install wscat. The collection of filters applied to the route. from the file menu. You signed in with another tab or window. We help brands across the globe design and build innovative products, platforms, and digital experiences for the modern world. You can extend an abstract class called AbstractGatewayFilterFactory. Java, Java SE, Java EE, and OpenJDK are trademarks of Oracle and/or its affiliates. The following example shows how to do so: You can route gateway routes to both HTTP and HTTPS backends. The following example configures a weight route predicate: This route would forward ~80% of traffic to weighthigh.org and ~20% of traffic to weighlow.org. The SetRequestHeader GatewayFilter factory takes name and value parameters. The following example configures a DedupeResponseHeader GatewayFilter: This removes duplicate values of Access-Control-Allow-Credentials and Access-Control-Allow-Origin response headers in cases when both the gateway CORS logic and the downstream logic add them. Spring Cloud Build brings along the basepom:duplicate-finder-maven-plugin, that enables flagging duplicate and conflicting classes and resources on the java classpath. Go to File Settings Editor Inspections. The RemoteAddr route predicate factory takes a list (min size 1) of sources, which are CIDR-notation (IPv4 or IPv6) strings, such as 192.168.0.1/16 (where 192.168.0.1 is an IP address and 16 is a subnet mask). The following listing configures a filter chain: The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. Support for all goodies from the Spring Cloud ecosystem (discovery, configuration, etc.) The arguments are typically listed in the order that would be needed for the shortcut configuration. Spring Cloud Gateway, or SCG for short, is a sub-project from the Spring Cloud family that provides an API gateway built on top of a reactive web . than cosmetic changes). The following listing defines a rate limiter that uses the KeyResolver defined in the previous listing: The RedirectTo GatewayFilter factory takes two parameters, status and url. SetRequestHeader is aware of URI variables used to match a path or host. The following examples show how to set up global pre and post filters, respectively: Spring Cloud Gateway provides a utility object called ProxyExchange. Plugin to import the same file. The url parameter should be a valid URL. This filter takes an optional keyResolver parameter and parameters specific to the rate limiter (described later in this section). 1. If nothing happens, download GitHub Desktop and try again. To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. The resulting response is similar to the following: The response contains the details of the global filters that are in place. We wont use it here, but its good to know we have this capability. The default is http|https|ftp|ftps. The following example configures a MapRequestHeader: This adds X-Request-Red: header to the downstream request with updated values from the incoming HTTP requests Blue header. AWS and Amazon Web Services are trademarks or registered trademarks of Amazon.com Inc. or its affiliates. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. tracker for issues and merging pull requests into master. The lowercase full name of the secure header needs to be used to disable it.. Route These are the building blocks of the gateway which contain URL to which request is to be forwarded to and the predicates and filters that are applied on the incoming requests. Retries are performed after a backoff interval of firstBackoff * (factor ^ n), where n is the iteration. Configuring Predicates and Filters For, 15.4. Make sure all new .java files to have a simple Javadoc class comment with at least an Spring Cloud Gateway Now, we'll create a Spring Cloud Gateway on port 3000 as a standard Spring Boot application with spring-cloud-starter-gateway as the only dependency and the standard main class. In our case, the implementation is trivial: It is so simple in this case because were using another built-in filter, ModifyResponseBodyGatewayFilterFactory, to which we delegate all the grunt work related to body parsing and type conversion. To allow for simple configuration in Java, the RouteLocatorBuilder bean includes a fluent API. The following listing shows how to modify a response body GatewayFilter: To add a filter and apply it to all routes, you can use spring.cloud.gateway.default-filters. You can find them in the spring-cloud-build-tools module. The input type is a Spring Framework ServerWebExchange. Bootstrap your application with Spring Initializr. The RemoveResponseHeader GatewayFilter factory takes a name parameter. To configure Global http timeouts: The following two examples are equivalent: For some usages of the gateway, properties are adequate, but some production use cases benefit from loading configuration from an external source, such as a database. This filter can be configured only by using the Java DSL. Spring Tools Suite or This is of particular use when using something like Spring Session with a lazy data store and you need to ensure the session state has been saved before making the forwarded call. This project adheres to the Contributor Covenant code of For the transformer class, we pass an instance of our Scrubber, which implements the required RewriteFunction interface in its apply() method: The first argument passed to apply() is the current ServerWebExchange, which gives us access to the request processing context so far. Spring CLoud Gateway Documentation shows the solution: 7. projects are imported into Eclipse you will also need to tell Spring Cloud Gateway comes with one non-default remote address resolver that is based off of the X-Forwarded-For header, XForwardedRemoteAddressResolver. A number of timeouts are associated with this handshake. The following listing configures a RewriteLocationResponseHeader GatewayFilter: For example, for a request of POST api.example.com/some/object/name, the Location response header value of object-service.prod.example.net/v2/some/object/id is rewritten as api.example.com/some/object/id. It offers a simple way to manipulate the request path by allowing templated segments of the path. The key point here is to use the apply() method variant that, instead of taking a configuration object, expects a Consumer for the configuration. 1. The MapRequestHeader GatewayFilter factory takes fromHeader and toHeader parameters. The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. When communicating over HTTPS, the client initiates a TLS handshake. Predicates and filters are specific to routes. Select Yes next to Assign endpoint. setting replenishRate=1, requestedTokens=60 and burstCapacity=60 will result in a limit of 1 request/min. The following example configures a SaveSession GatewayFilter: If you integrate Spring Security with Spring Session and want to ensure security details have been forwarded to the remote process, this is critical. There, youll have to define where the checkstyle rules should be picked from. To clear the routes cache, make a POST request to /actuator/gateway/refresh. If you dont have an IDE preference we would recommend that you use #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. The following listing shows how to modify a request body GatewayFilter: You can use the ModifyResponseBody filter to modify the response body before it is sent back to the client. The pattern is an Ant-style pattern with . Hence add the property suggested [spring.main.web-application-type=reactive]. The Spring Cloud Gateway project is built on top of the popular Spring Boot 2 and Project Reactor, so it inherits its main treats: Low resource usage, thanks to its reactive nature. In this tutorial, we'll explore the main features of the Spring Cloud Gateway project, a new API based on Spring 5, Spring Boot 2 and Project Reactor. The following example configures a Spring Cloud CircuitBreaker GatewayFilter: To configure the circuit breaker, see the configuration for the underlying circuit breaker implementation you are using. Temporary bursts can be allowed by setting burstCapacity higher than replenishRate. When a request matches a route, the filtering web handler adds all instances of GlobalFilter and all route-specific instances of GatewayFilter to a filter chain. Please You can combine multiple route predicate factories with logical and statements. If no-one else is using your branch, please rebase it against the current master (or ), The NettyWriteResponseFilter runs if there is a Netty HttpClientResponse in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute. to use Codespaces. So, now that we know the contract for a rewrite function, lets finally implement our scrubber logic. If it is not matched, the filter does nothing. The following example configures such a fallback: The following listing does the same thing in Java: This example forwards to the /inCaseofFailureUseThis URI when the circuit breaker fallback is called. Please point it to the Spring Cloud Builds, spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml file either in your cloned repo or via the https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml URL. This server will handle the request at /customer and return a fixed JSON response used in our tests. The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). Did a developer include a header indicating an API version? 2023 VMware, Inc. or its affiliates. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. The request returns a 200 without a response body. Route: A route is the basic component of a gateway. To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). There click on the icon next to the Profile section. The /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. Note that this example also demonstrates the (optional) Spring Cloud Netflix Ribbon load-balancing (defined by the lb prefix on the destination URI). Contributor License Agreement. To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. We recommend the m2eclipse eclipse plugin when working with any changes in the README it will then show up after a Maven build as The redis-rate-limiter.requestedTokens property is how many tokens a request costs. OAuth Resource Server. The algorithm used is the Token Bucket Algorithm. require that a local instance of [Docker](https://www.docker.com/get-started) is installed and running. the spring milestone and snapshot repositories. 1. When writing a commit message please follow these conventions, Spring Cloud Gateway includes many built-in GatewayFilter Factories. If you are routing to an HTTPS backend, you can configure the gateway to trust all downstream certificates with the following configuration: Using an insecure trust manager is not suitable for production. If using IntelliJ, you can use the Here, you can modify requests and responses before or after sending the downstream request. Spring Cloud Gateway matches routes as part of the Spring WebFlux HandlerMapping infrastructure. The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. When combined with setting the reactor.netty log level to DEBUG or TRACE, it enables the logging of information, such as headers and bodies sent and received across the wire. author credit if we do. All pre filter logic is executed. projectRoot/src/checkstyle/checkstyle-suppresions.xml. eclipse. see many different errors related to the POMs in the projects, check Secondly, we programmatically create a route @Bean that includes our filter. The PrefixPath GatewayFilter factory takes a single prefix parameter. The filter takes a maxSize parameter. 1. It then builds a registry of available filters that we can use when declaring routes: Notice that, when using this configuration-based approach to define routes, it is important to name our factory according to SCGs expected naming convention: FilterNameGatewayFilterFactory. 2. unacceptable behavior to spring-code-of-conduct@pivotal.io. GatewaySampleApplication.java, 4. It must be a Java System Property, not a Spring Boot property. GlobalLogic is a leader in digital engineering. The following describes an alternative style gateway. Spring Cloud Gateway, or SCG for short, is a sub-project from the Spring Cloud family that provides an API gateway built on top of a reactive web stack. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. For instance, in the configuration above, apply() will be called only once since theres just a single route definition. SCG calls this method for every route definition that uses our filter. The following example configures a query route predicate: The preceding route matches if the request contained a green query parameter. Spring Cloud Gateway handles cross-cutting concerns for API development teams, such as single sign-on (SSO), access control, rate-limiting, resiliency, security, and more. The body is cached in a request attribute defined by. This predicates matches the Host header that matches the pattern. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. The following example configures a cookie route predicate factory: This route matches requests that have a cookie named chocolate whose value matches the ch.p regular expression. Features. follow the guidelines below. Learn more. The FallbackHeaders factory lets you add Spring Cloud CircuitBreaker execution exception details in the headers of a request forwarded to a fallbackUri in an external application, as in the following scenario: In this example, after an execution exception occurs while running the circuit breaker, the request is forwarded to the fallback endpoint or handler in an application running on localhost:9994. AddRequestHeader is aware of the URI variables used to match a path or host. The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. With MVC, it also supports forwarding to a local handler through the forward() method. A Spring Cloud Gateway instance routes traffic according to rules. URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. This route matches if the request has a Host header with a value of www.somehost.org or beta.somehost.org or www.anotherhost.org. This is equivalent to building a route using configuration properties but allows us to have full control of all aspects of the test route: Finally, with those beans now part of a @TestConfiguration, we can inject them into the actual test, together with a WebTestClient. README.adoc and process it by loading all the includes, but not Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. Typically, there will be a name key and an args key. Easy to extend and/or customize using standard Spring patterns profile to be active, or you may experience build errors. They can also be We'll also configure the routing to access the greeting service: A burst of 20 is allowed, but, in the next second, only 10 requests are available. The datetime2 parameter must be after datetime1. you can import formatter settings using the Thank you Introduction. statuses: The HTTP status codes that should be retried, represented by using org.springframework.http.HttpStatus. Spring Cloud Gateway Quick Recap. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. Predicates and filters are specific to routes. Cloud Build project. If the new named header already exists, its values are augmented with the new values. This configuration object provides the setRewriteFunction() method were calling in our code. The following listing configures a RemoveResponseHeader GatewayFilter: This will remove the X-Response-Foo header from the response before it is returned to the gateway client. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. *) and the replacement /${remaining}. The next argument is the received body, already converted to the informed in-class. The gateway can listen for requests on HTTPS by following the usual Spring server configuration.
