How is security implemented in Spring Cloud Gateway?
Pattern 1: OpenID Connect Authentication
- Create a Eureka discovery service.
- Create a Spring Cloud Gateway application.
- Create a REST API service.
- Direct the REST API through the Spring Cloud Gateway.
- Create a microservice.
- Secure the Micro Service using OAuth 2.0 Scopes.
- Update the REST API to call the microservice.

What is spring cloud security?
Spring Cloud Security offers a set of primitives to build secure applications and services with a minimum of fuss. Building on Spring Boot and Spring Security OAuth2, we can quickly build systems that implement common patterns like single sign-on, token relay, and token swapping.
How do I use Spring Cloud Gateway with JWT?
Authentication/authorization flow
- Endpoint user registration/registration with username, password and role(s).
- User information is stored in the database.
- The user logs in to the endpoint/login with the username and password that the user used in step 1.
- The user receives JWT (JSON Web Token) upon successful login.
What can Spring Cloud Gateway do?
Spring Cloud Gateway provides a library to build API gateways on top of Spring and Java. It provides a flexible way to route requests based on a set of criteria, as well as focusing on cross-cutting issues like security, resiliency, and monitoring.
Why do we use Spring Cloud?
Spring Cloud provides tools for developers to quickly build some of the common patterns in distributed systems (for example, configuration management, service discovery, circuit breakers, smart routing, micro-proxy, control bus, unique tokens, global locks, election leadership, session distribution, cluster status).
How to secure services with Spring Cloud Gateway?
To protect our services, we will use the Token Relay pattern compatible with OAuth 2.0 and the Javascript Object Signing & Encryption (JOSE) and JSON Web Tokens standards. This will give our users a means to identify themselves, authorize applications to view their profile, and access the secure resources behind the gateway.
How does token relay work in Spring Cloud Gateway?
A token relay occurs when an OAuth2 consumer, such as API Gateway, acts as a client and forwards the access token to the routed service. Let’s create a shopping cart service.
How to remove cookie from Spring Cloud Gateway?
removeRequestHeader(“Cookie”) tells the gateway to remove the users “Cookie” header from the request during the routing operation (because downstream services don’t need this, all they need is the JWT access token ). The following YAML configuration accomplishes the same thing, but without the need for Java code:
What is the filterfactory method in Spring Cloud Gateway?
The filterFactory.apply() method on the route declaration ensures that any exchange destined for the resource server contains a JWT access token.
Is it used by Spring for authentication?
At its core, Spring Security is really just a set of servlet filters that help you add authentication and authorization to your web application. It also integrates well with frameworks like Spring Web MVC (or Spring Boot) as well as standards like OAuth2 or SAML.
What is the responsibility of the Spring Cloud API gateway?
How do I use Spring Security authentication?
The authentication object is stored in the SecurityContext object by the filter for future use.
- An authentication object with authenticated=true if Spring Security can validate the supplied user credentials.
- An AuthenticationException if Spring Security finds that the supplied user credentials are invalid.
What is authentication filter in Spring Security?
A filter that performs authentication for a particular request. If the authentication is successful, the AuthenticationSuccessHandler is invoked and the authentication is set to the SecurityContextHolder; otherwise, AuthenticationFailureHandler is invoked.
What is the difference between Spring Cloud Gateway and ZUUL?
Zuul is based on servlet 2.5 (works with 3.x), using blocking API. Does not support long-lived connections such as websockets. Gateway is based on Spring Framework 5, Project Reactor, and Spring Boot 2 using non-blocking APIs.
What is Spring Cloud Gateway with Spring Security?
We have SCG, UAA, Resource1, Resource2 services. UAA or User Account & Authentication is a PCF authentication and authorization service. In a nutshell, it is AuthServer built with SpringBoot. We are using UAA warfare and deploying it to our local servlet container tomcat.
What is springboot UAA or user account and authentication?
UAA or User Account & Authentication is a PCF authentication and authorization service. In a nutshell, it is AuthServer built with SpringBoot. We are using UAA warfare and deploying it to our local servlet container tomcat. Of course we could have built our own AuthServer, this is just to save time and focus on the purpose of this post.
