Spring Cloud Gateway Quick Recap. With MVC, it also supports forwarding to a local handler through the forward() method. The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. 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. For a production deployment, you can configure the gateway with a set of known certificates that it can trust with the following configuration: If the Spring Cloud Gateway is not provisioned with trusted certificates, the default trust store is used (which you can override by setting the javax.net.ssl.trustStore system property). 1. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. As a result, you can inject request headers and query parameters, for instance, and you can constrain the incoming requests with declarations in the mapping annotation. Bootstrap your application with Spring Initializr. The filter also looks in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR attribute to see if it equals lb. The following headers (shown with their default values) are added: Strict-Transport-Security (max-age=631138519), Content-Security-Policy (default-src 'self' https:; font-src 'self' https: data:; img-src 'self' https: data:; object-src 'none'; script-src https:; style-src 'self' https: 'unsafe-inline)'. Now, lets get a little deeper on setRewriteFunction(). Fails the build upon Checkstyle violations, Checkstyle analyzes also the test sources, Add the Spring Java Format plugin that will reformat your code to pass most of the Checkstyle formatting rules, Add checkstyle plugin to your build and reporting phases. Contributor License Agreement. line length needs to be longer), then its enough for you to define a file under ${project.root}/src/checkstyle/checkstyle-suppressions.xml with your suppressions. If no-one else is using your branch, please rebase it against the current master (or It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. First, you must get the assigned public endpoint for Spring Cloud Gateway and API portal by following these steps: Open your Enterprise tier service instance in Azure portal. At startup, Spring looks for any @Component-annotated class that implements this interface. The following example configures a PrefixPath GatewayFilter: This will prefix /mypath to the path of all matching requests. You can extend an abstract class called AbstractGatewayFilterFactory. The filter also looks in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR attribute to see if it equals lb. The name and argument names will be listed as code in the first sentance or two of the each section. Route: A route is the basic component of a gateway. 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 SetStatus GatewayFilter: In either case, the HTTP status of the response is set to 401. Most examples below use the shortcut way. The pattern is an Ant-style pattern with . 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. So, if the downstream server responded with a X-Request-Red:1234, this would be replaced with X-Request-Red:Blue, which is what the downstream service would receive. status: The HTTP status of the request returned to the client. Spring Cloud Gateway features: Built on Spring Framework 5, Project Reactor and Spring Boot 2.0. A steady rate is accomplished by setting the same value in replenishRate and burstCapacity. To configure per-route timeouts: Predicates and filters are specific to routes. Other IDEs and tools For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. You can add headers to the downstream response by using the header() methods on ProxyExchange. The following example configures a between route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver) and before Jan 21, 2017 17:42 Mountain Time (Denver). Here, well use one thats commonly used by the out-of-the-box filters: AbstractGatewayFilterFactory, a templated base class, where T stands for the configuration class associated with our filter instances. If nothing happens, download Xcode and try again. The algorithm used is the Token Bucket Algorithm. Note that the $ should be replaced with $\ because of the YAML specification. Websocket Sample. 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. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. Other names may be trademarks of their respective owners. The path part of the request URL is overridden with the path in the forward URL. In this tutorial, we'll look at how we use Spring Cloud Gateway to inspect and/or modify the response body before sending it back to a client. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments. The arguments are typically listed in the order that would be needed for the shortcut configuration. If the URL has a lb scheme (such as lb://myservice), it uses the Spring Cloud ReactorLoadBalancer to resolve the name (myservice in this example) to an actual host and port and replaces the URI in the same attribute. As filters are a core concept in SCG, all we need to do to support response processing is to implement a custom one that applies the desired transformation. Spring Cloud Gateway. The RewriteLocationResponseHeader GatewayFilter factory modifies the value of the Location response header, usually to get rid of backend-specific details. Using JsonNode as the input/output type allows us to process any valid JSON payload, which we want in this case. There click on the icon next to the Scheme section. author credit if we do. So, as long we dont do any kind of blocking I/O operation, we can do some complex work inside the rewrite function. statuses: The HTTP status codes that should be retried, represented by using org.springframework.http.HttpStatus. than cosmetic changes). The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). This configuration object provides the setRewriteFunction() method were calling in our code. The following example configures a RemoveRequestParameter GatewayFilter: This will remove the red parameter before it is sent downstream. name can contain a space-separated list of header names. AddResponseHeader is aware of URI variables used to match a path or host. The default is 'B' for bytes. To run your own gateway use the spring-cloud-starter-gateway dependency. SetResponseHeader is aware of URI variables used to match a path or host. The most notable files under the module are: Checkstyle rules are disabled by default. youre working on spring-cloud-contract. m2eclipse eclipse plugin for maven support. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. As part of that process it will look for a Use Git or checkout with SVN using the web URL. Go to File Settings Editor Inspections. Easy to write Predicates and Filters. If you dont have an IDE preference we would recommend that you use Basically, the spring boot gateway provides a simple and effective way to route API's. If you want to customize the predicates or filters used by the DiscoveryClient routes, set spring.cloud.gateway.discovery.locator.predicates[x] and spring.cloud.gateway.discovery.locator.filters[y]. marketplace". If the URI has a scheme prefix, such as lb:ws://serviceid, the lb scheme is stripped from the URI and placed in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR for use later in the filter chain. The key point here is to use the apply() method variant that, instead of taking a configuration object, expects a Consumer for the configuration. There click on the icon next to the Profile section. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. Cloud Build project. projectRoot/src/checkstyle/checkstyle-suppresions.xml. To have Intellij work with Checkstyle, you have to install the Checkstyle plugin. Spring Cloud Gateway includes many built-in GatewayFilter Factories. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. 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. We can route that request to the appropriately versioned backend. The next argument is the received body, already converted to the informed in-class. For example, to reference a filter named Something in configuration files, the filter Spring Cloud Build comes with a set of checkstyle rules. You can configure these timeouts can be configured (defaults shown) as follows: Configuration for Spring Cloud Gateway is driven by a collection of RouteDefinitionLocator instances. Check out all the upcoming events in the Spring community. spring-cloud gateway az spring-cloud gateway route-config Reference Feedback Note This reference is part of the spring-cloud extension for the Azure CLI (version 2.30.0 or higher). Redis) for testing generally The default request size is set to five MB if not provided as a filter argument in the route definition. The reason the filters are divided by the dotted line is that filters can run logic both before and after the proxy request is sent. It is the permissible size limit of the request defined in bytes. Predicate: This is a Java 8 Function Predicate. To enable wiretap, set spring.cloud.gateway.httpserver.wiretap=true or spring.cloud.gateway.httpclient.wiretap=true for the HttpServer and HttpClient, respectively. The redis-rate-limiter.requestedTokens property is how many tokens a request costs. Spring Cloud CircuitBreaker GatewayFilter Factory, 12.4.1. Notice that the returned server is already started and will listen to incoming requests at a random port. Just commit it and push the change. To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. To change the default values, set the appropriate property in the spring.cloud.gateway.filter.secure-headers namespace. Import the spring-cloud-build-tools/src/main/resources/intellij/Intellij_Spring_Boot_Java_Conventions.xml file. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. If the Gateway Handler Mapping determines that a request matches a route, it is sent to the Gateway Web Handler. eclipse. In this scenario, any unauthenticated incoming request will initiate an authorization code flow. Request Rate Limiting. Thank you The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. It is defined by an ID, a destination URI, a collection of predicates, and a collection of filters. The following table describes the structure of each element (each is a route) of the response: The GatewayFilter factories applied to the route. Spring Cloud Gateway is API Gateway implementation by Spring Cloud team on top of Spring reactive ecosystem. Make sure all new .java files to have a simple Javadoc class comment with at least an In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. It uses the Spring WebSocket infrastructure to forward the websocket request downstream. In this case, the rate limiter needs to be allowed some time between bursts (according to replenishRate), as two consecutive bursts will result in dropped requests (HTTP 429 - Too Many Requests). If the URL has a scheme of lb (such as lb://myservice), it uses the Spring Cloud LoadBalancerClient to resolve the name (myservice in this case) to an actual host and port and replaces the URI in the same attribute. OAuth Resource Server. 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. The Spring Cloud CircuitBreaker filter can also accept an optional fallbackUri parameter. 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. Setting this value to zero blocks all requests. The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. Terminology. After the proxy request is made, the post filter logic is run. The gateway can listen for requests on HTTPS by following the usual Spring server configuration. following command: The generated eclipse projects can be imported by selecting import existing projects *) and the replacement /${remaining}. per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 64. Here, you can modify requests and responses before or after sending the downstream request. If you prefer not to use m2eclipse you can generate eclipse project metadata using the To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). It will provide an easy way for routing requests based on number criteria; it will also focus on monitoring and security of an application. Each item defines the name and the arguments of a given predicate. For instance, given a JSON having a field named ssn: We want to replace their values with a fixed one, thus preventing a data leakage: A GatewayFilterFactory is, as the name implies, a factory for filters of a given time. So a request to /hello would be sent to /mypath/hello. conduct. src/main/asciidoc. VMware Spring Cloud Gateway is a commercial VMware Tanzu component based on the open-source Spring Cloud Gateway project. The actual test uses this WebTestClient to drive both the spun SCG and the backend: In this article, weve shown how to access the response body of a backend service and modify it using the Spring Cloud Gateway library. 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. other target branch in the main project). Note that the null value is due to an incomplete implementation of the endpoint controller, because it tries to set the order of the object in the filter chain, which does not apply to a GatewayFilter factory object. This method takes three arguments: two classes (in and out) and a function that can transform from the incoming type to the outgoing. If routing to a https backend then the Gateway can be configured to trust all downstream certificates with the following configuration: application.yml. With that in mind, well name our factory ScrubResponseGatewayFilterFactory. require that a local instance of [Docker](https://www.docker.com/get-started) is installed and running. If the new named header already exists, its values are augmented with the new values. The SetRequestHeader GatewayFilter factory takes name and value parameters. It is the name of the query parameter to be removed. This uses the URI templates from Spring Framework. Go to File Settings Editor Code style. To write a custom global filter, you must implement GlobalFilter interface. 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. TLS / SSL. The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. 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. keyResolver is a bean that implements the KeyResolver interface. Add some Javadocs and, if you change the namespace, some XSD doc elements. 1. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchOptionalTrailingSeparator. There, click on the Import Scheme value and pick the Intellij IDEA code style XML option. There, click on the Import Profile and import the spring-cloud-build-tools/src/main/resources/intellij/Intellij_Project_Defaults.xml file. The preceding route matches if the request contained a red query parameter whose value matched the gree. As Spring Cloud Gateway distinguishes between pre and post phases for filter logic execution (see How it Works), the filter with the highest precedence is the first in the pre-phase and the last in the post-phase. This filter takes an optional keyResolver parameter and parameters specific to the rate limiter (described later in this section). To enable the Spring Cloud CircuitBreaker filter, you need to place spring-cloud-starter-circuitbreaker-reactor-resilience4j on the classpath. 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. from the file menu. Hence add the property suggested [spring.main.web-application-type=reactive]. The following example configures a RemoteAddr route predicate: This route matches if the remote address of the request was, for example, 192.168.1.10. 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. the ID of the service from the DiscoveryClient. This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer. To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. The following listing shows the KeyResolver interface: The KeyResolver interface lets pluggable strategies derive the key for limiting requests. The Reactor Netty HttpClient and HttpServer can have wiretap enabled. The following example configures CORS: In the preceding example, CORS requests are allowed from requests that originate from docs.spring.io for all GET requested paths. This predicates matches the Host header that matches the pattern. The gateway maintains a client pool that it uses to route to backends. The Spring Cloud CircuitBreaker GatewayFilter factory uses the Spring Cloud CircuitBreaker APIs to wrap Gateway routes in A burst of 20 is allowed, but, in the next second, only 10 requests are available. It is possible to create a gateway filter named without the. The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. 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. Currently, only forward: schemed URIs are supported. In this tutorial, well look at how we use Spring Cloud Gateway to inspect and/or modify the response body before sending it back to a client. All other trademarks and copyrights are property of their respective owners and are only mentioned for informative purposes. However, you can point to the Spring Cloud Builds GitHub repository (e.g. The spring-cloud-build module has a "docs" profile, and if you switch Typically, there will be a name key and an args key. spring: cloud: gateway: httpclient: ssl . URI variables may be used in the value and are expanded at runtime. Retries are performed after a backoff interval of firstBackoff * (factor ^ n), where n is the iteration. connect-timeout must be specified in milliseconds. If there is a Route object in the ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR exchange attribute, the RouteToRequestUrlFilter runs. For more detailed examples of how to use any of the following filters, take a look at the. The body is cached in a request attribute defined by. For the external controller/handler scenario, headers can be added with exception details. The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. The following examples show how to set up global pre and post filters, respectively: Spring Cloud Gateway provides a utility object called ProxyExchange. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). 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. Spring Cloud Gateway Architecture. You can customize the way that the remote address is resolved by setting a custom RemoteAddressResolver. The following maxTrustedIndex values yield the following remote addresses: (invalid, IllegalArgumentException during initialization). The following listing configures a redis-rate-limiter: Rate limits bellow 1 request/s are accomplished by setting replenishRate to the wanted number of requests, requestedTokens to the timespan in seconds and burstCapacity to the product of replenishRate and requestedTokens, e.g. a modified file in the correct place. Spring Cloud Gateway is mainly used in one of the following roles: OAuth Client. See the documentation for @RequestMapping in Spring MVC for more details of those features. available to Maven by setting a, Older versions of m2e do not support Maven 3.3, so once the The expected return is a Publisher of instances of the informed out-class. It adds more detail to each route, letting you view the predicates and filters associated with each route along with any configuration that is available. This handler runs the request through a filter chain that is specific to the request. In another, run a client, connecting through gateway: wscat --connect ws://localhost:8080/echo. The Spring Cloud Gateway has three important parts to it. Signing the contributors agreement does not grant anyone commit rights to the main The following listing configures a filter chain: The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. This strips the service ID from the path before the request is sent downstream. Reference https://www.baeldung.com/spring-cloud-gateway-response-body, ScrubResponseGatewayFilterFactory scrubFilterFactory, SetPathGatewayFilterFactory pathFilterFactory, givenRequestToScrubRoute_thenResponseScrubbed, Spring Data Jpa Multiplebagfetchexception, Bulk Update With Spring Data MongoDB Reactive, https://www.baeldung.com/spring-cloud-gateway-response-body, Keep compatibility with existing clients while allowing the backend to evolve, Masking some fields from the response to comply with regulations like PCI or GDPR. If you use Eclipse Then, by default, the gateway metrics filter runs as long as the property spring.cloud.gateway.metrics.enabled is not set to false. If you need to add ignoredClassPatterns or ignoredResourcePatterns to your setup, make sure to add them in the plugin configuration section of your project: This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. This predicate matches requests that happen after the specified datetime. It comprises of . The weights are calculated per group. It is added to the ServerWebExchange as the ServerWebExchangeUtils.CIRCUITBREAKER_EXECUTION_EXCEPTION_ATTR attribute that can be used when handling the fallback within the gateway application. install wscat. The following example creates a Logback configuration: You can configure the gateway to control CORS behavior. that you have an up to date installation. Spring cloud gateway provides a library for building gateway API on top of java and spring. Kubernetes is a registered trademark of the Linux Foundation in the United States and other countries. This is the full configuration of the shortcut configuration of the Cookie predicate shown above. You can adjust this behavior by setting the spring.cloud.gateway.filter.request-rate-limiter.deny-empty-key (true or false) and spring.cloud.gateway.filter.request-rate-limiter.empty-key-status-code properties. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. The following MVC example proxies a request to /test downstream to a remote server: The following example does the same thing with Webflux: Convenience methods on the ProxyExchange enable the handler method to discover and enhance the URI path of the incoming request. We recommend the m2eclipse eclipse plugin when working with To build the source you will need to install JDK 17. We wont use it here, but its good to know we have this capability. 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 Support for all goodies from the Spring Cloud ecosystem (discovery, configuration, etc.) It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. A utility method (called get) is available to make access to these variables easier. Route matching built into Spring Handler Mapping, Route matching on HTTP Request (Path, Method, Header, Host, etc), Filters can modify downstream HTTP Request and HTTP Response (Add/Remove Headers, Add/Remove Parameters, Rewrite Path, Set Path, Hystrix, etc), Supports Spring Cloud DiscoveryClient for configuring Routes. Spring Cloud Build brings along the basepom:duplicate-finder-maven-plugin, that enables flagging duplicate and conflicting classes and resources on the java classpath. This section details how to retrieve route filters, including: To retrieve the global filters applied to all routes, make a GET request to /actuator/gateway/globalfilters. A route is matched if the aggregate predicate is true. Please report The Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. The following example configures a path route predicate: This route matches if the request path was, for example: /red/1 or /red/blue or /blue/green. response-timeout must be specified as a java.time.Duration. Terms of Use Privacy Trademark Guidelines Your California Privacy Rights Cookie Settings. The resulting response is similar to the following: The response contains the details of the global filters that are in place. Spring Cloud supports Resilience4J out of the box. The resulting response is similar to the following: The response contains the details of the GatewayFilter factories applied to any particular route. You must use $\ to mean $ because of the YAML specification. By default, when a service instance cannot be found in the, By default, when a service instance cannot be found by the. 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.
